Item
Failure to familiarize yourself with all terrain features along your
flight path has been judged by the FAA as a violation of the FARs.
Cross-Country
Student Pilot Experience Requirements
Each flight with a landing at a point more than 50 nautical miles from the
original departure point counts as cross-country time. Once flight must have
landings at a minimum of three points, one of which is at least 100 nautical
miles from the original departure point. FAR 61.109(b)(2) and
61.129(b)(3)(ii). An instrument student must have 50 hours of cross-country
time subsequent to getting the private pilot rating.
Cross-Country Checkride
Test covers pilotage, dead reckoning, radio navigation, diversion to an
alternate and lost procedures. Course must be long enough to check
weight/balance and fuel calculations. PTS is said to allow flight to three
miles either side of course. Altitude within 200'. You should hold to less
than 1/4 mile off-course before making a correction. Radio navigation requires
you to select and identify a navaid, locate your position, intercept and track
a radial/bearing and note station passage. Diversion to an alternate requires
you to pass a knowledge portion during the oral. Altitude and airspeed control
is required as is prompt diversion to alternate with approximate heading,
ground speed, fuel consumption, and ETA. All oral information is covered in
Chapter 7 of AC 61-23B and AC 61-21A.
Lost procedures are usually covered during the oral. There are ways of
creating "lost" situations in flight. Be prepared to demonstrate
sufficient skill and knowledge to select the best course of action.
Airport/Facilities
Directory
You will need a current Airport/Facilities Directory (A/FD). These are
published every 56 days and contains supplemental information about airports
and nav aids that cannot be easily places on sectionals. The FAA does not say
that a pilot must have an A/FD, they do imply that you will be sorry if you
don't.
The Airport/Facility directory has current information on airports,
facilities, frequencies and procedures. GPS information is still to come.
Airports are identified as to type of operation and special procedures
available. Radar facilities and specialty information is listed such as
Doppler radar and FSS facilities. Included are phone numbers
--1/3 of all VOR have direction/altitude restrictions that are spelled out in
the A/FD. Get one before you begin making your cross-country flights. FAR
91.103 prescribes preflight action that can only be taken by having an A/FD.
--Center frequencies are in the back. Once NOTAMS have been published in the
A/FD they are unavailable in routine briefings of NOTAMS you get by asking the
FSS technician.
--Sectional chart changes of frequencies, outages, noise abatement, closures,
that become semi-permanent are only available in the A/FD. This means that
only the latest edition is a valid issue.
--Special Notices section.
The Pilot Operating
Handbook
You will need a Pilot Operating Handbook (POH) specific to the year and
model of the aircraft. You need it to confirm that the airports, runway
lengths, elevations, times and distances are within the performance
capabilities of your aircraft. FAR 91.151 indicates that you must have enough
fuel to fly to your intended destination + 30 minutes day and 45 minutes night
reserve. A fuel stop is not a waste of time, it provides time for you to make
considered decisions and safer options.
Cross-Country Planners:
These computer plans cost several hundreds of dollars. They are optimized
for your aircraft and will be will be direct, efficient and will take all the
available information into the planning.
AOPA now has a Planner (2003)

9. Set your flight standards
10. VFR, Wind velocities, fuel reserves, course tolerance, changing course
options, altitude selection, communications.
11. Plan your checkpoints
12. Spacing, timing, ETAs, checklist emergency options, descent point
13. Plan your worst case situation
14. First, fly the plane, radio options
And More
--Basic VFR uses pilotage with a line on a map, checkpoints and compass
heading.
--Practice with a chart over familiar areas will show you that what you see is
not always on the chart.
--The ability to select useable checkpoints on a route is a basic skill best
taught and learned by practice.
--Checkpoints are best if evenly spaced backwards from destination and on the
left side of aircraft.
--Fly visually between two checkpoints at your cruising altitude and you have
the required compass heading from your compass.
--Get the time between evenly spaced checkpoints and you can get your
estimated time of arrival (ETA) and ground speed.
--Dead (Ded) reckoning is done the same way as pilotage but assumes you have
no visual references.
--Add five minutes for every departure and another five for arrival if flight
is below 5000 feet.
--Pilotage begins with line on the map, the true course, variation correction
gives you magnetic course, wind
correction gives you magnetic heading and the deviation card gives compass
heading.
--Magenta dashed lines on the chart gives the + variation required
--True winds from an FSS are used with true course on map to determine wind
correction angle.
--Pilotage can be done by drawing true vectors of course and wind with a
protractor and ruler just as accurately as with an E6-B
--True airspeed figures are obtained from POH for power setting and altitude
selected.
--In most situations once you are flying you use your magnetic course numbers
written on the chart.
--The assumption is (correctly) that the wind will never be as forecast.
--You must be on your magnetic course to use the wing tip to determine time at
a checkpoint.
--An airport vicinity route will seldom make a big difference in your time en
route.
--Use cruise climb or less if winds are against you. High winds are stronger.
--Climb high to pick up favorable winds.
--Fly to right side of valleys and roads
--Lean your mixture.
--Watch the weather movements and fly a day before or two days after a front.
--Vertical planning is more likely to cause an accident than lateral planning.
--Scud running (down and dirty) requires intimate knowledge of the area.
--Mountain flying tends to be along passes. AWOS is becoming available in
passes.
--Always plan a backdoor option for mountain flying.
--Don't attempt marginal VFR flying at night. The odds are against you.
Planning a
Cross-Country
I have my students get as much on the sectional as they can in the way of
airport frequencies and information. Of all the cockpit papers the sectional
is the most useful to have readily at hand and least likely to get lost. I do
not require a 'conventional log' but I do ask them to make a log of their own
design with all the checkpoints, Altitudes, MC, WCA, MH, ETA/ATA, Fuel use,
etc. Before the flight we transfer all of the practical information on to the
sectional. Then we fly the flight and write the info on the sectional as it
occurs and can be reverenced directly with surface below. After the flight the
information can be written in the log. My intention is to have the information
where it is both available and meaningful.
Pilot judgment is a process, which produces a thoughtful, considered and
pre-planned decision relating to the aircraft's operation along with the
action/inaction to go with that decision. The ability to make the best
decision involves searching for and establishing the relevance of all
available information regarding a flying situation, specifying alternative
courses of action and determining expected outcomes from each. The more
knowledge we have the greater the resources on which we have to draw to
evaluate a situation and specify a course of action.
Plan to navigate in straight lines where terrain and airports make such flight
safe. Often a dogleg near the beginning or end of the flight will permit a
much safer, lower, and airport vicinity routing. Try to minimize flight time
but remember fuel stop time can be avoided by slower flight speeds. Again, a
fuel stop does not waste time. It buys decision making time and provide safer
options. Evaluate fuel remaining at every third checkpoint during a flight.
Compare your estimates with actual consumption every time you refuel.
Of all the cross-country planning decisions, the no-go decision is the most
difficult to make and stick to. We all want to fly. The patience to accept
that the figures just do not add up to equal a safe flight takes some
seasoning to be come part of your planning. Non-pilots seem all to ready to
fly when they have absolutely no comprehension of the hazards involved. You,
the pilot, must recognize that only your judgment, training, and skill can
make the safe decision.
The preliminaries an instructor uses to determine if a student has properly
prepared for a cross-country will cover up to forty different areas. The
questioning will cover the FARs, weight and balance, route selection,
checkpoint selection, altitude selection, radio procedures, weather and all
else needed to file and fly a flight plan. Additional areas include procedures
knowledge, use of references, aircraft manual use, maintenance records,
required paper work, chart reading, fuel consumption, speed computation and
decision making.
BEGINNING:
1. Locate destinations on sectional
2. Draw multiple lines /// between points
3. Starting from destinations try to locate checkpoints that are evenly spaced
so that only the first point after departure is uneven. (This makes ETA easy)
Z-marker instead of straight lines might be a better way for writing
information along course line..
Timing
Checkpoints
Timing is essential. However, the workload can be greatly reduced by
selecting visual/VOR checkpoints
that allow for evenly spaced distances between points. You work backwards from
your destination working along the True Course line. With a bit of effort you
can get points that allow similar spacing distances ranging from 10 to 20
miles along the route. Only your distance from departure airport to first
checkpoint would be at variance.
The advantage of this should be obvious. Once you have the time between the
first and second checkpoint
after departure you can easily determine your ETA for the remainder of the
trip. ETA changes can be made
as wind affects the times.
One of the best benefits of this method is that it is likely to make you study
the route more carefully than you would otherwise. Once you have made this
method work you will never try any other method other than GPS.
Key Elements of Cross-Country Planning
Preflight preparation and planning is the foundation of safe flying. The
failure to recognize the importance of a comprehensive preflight is an
invitation to in-flight difficulties. Primary consideration is the condition of
the pilot. It takes only one 'risk element' to make a flight no-go.
0.5. Aircraft papers
--Airworthiness certificate
--Registration certificate
--POH or FM on aircraft
--Weight and balance papers
1. Charts
--The line on the cart represents true course
--The sectional has 8-miles to the inch so a ruler can be used to mark
checkpoint distances from the straight-line
destination back to the departure either in 8 or 16 mile segments as desired.
Quick and easy. Use visual
checkpoints to the left of course where possible and VORs left or right when
the intercept angle is 60-degrees
or greater.
-- WAC charts are 16 miles to the inch.
--WAC charts have limited communications and airport information but are
useful on longer flights.
--The use of out of date charts or WAC charts for local navigation is a
hazardous practice.
--Any flight within the boundaries of an area chart requires possession of
that area chart in the aircraft.
--Carrying a current AF/D will give you considerable information not available
on charts.
2. Route
--The temptation to fly direct air routes is great. However, the economies of
direct route often expose the flight to
unnecessary hazards.
--Select alternate routes.
--Review minimum enroute altitudes.
--Fly low to study terrain clearance. Use this knowledge when flying at night.
--By flying small ifr (I follow roads) or an airport vicinity route you
increase your options.
--A slight bend in your route will allow you to avoid over flying high peaks,
desolate areas or large bodies of water.
3. The Aeronautical Information Manual
--Answers most airspace questions
4. NOTAMS
--Ask the FSS for all NOTAMS for the route you are taking. This applies to
information for all NAVAIDS and
airports.
5. Weather
--What you are looking for is any information that will affect the go/no go
decision
6. Navigation Log
--Computed from true course to magnetic course to compass course with wind
correction angle to get true
heading to magnetic heading to compass heading for each straight leg of the
route.
--get all NOTAMS related to navaids for the route. Put radar frequencies on
chart of each area.
6.5 Avionics
--Confirm latest VOR check
--FCC station license
--Com frequencies in and squelch checked
--Navigational frequencies in
--ELT check within five after the hour
7. Flight Plan
--Filing is not required by FAR but it is both a good operating practice and
to be expected on a PP checkride.
Along with filing you should know the proper radio procedures for contacting
an FSS. how to open, extend,
make a position report, and all the methods to close a flight plan. The FSS
often has difficulty handling a
DUATS flight plan. An FSS may have up to twelve different frequencies so you
must know how to get the
proper frequency from a sectional. On occasion the transmitter frequency
(122.1) will be different from the
VOR receiver frequency.
8. Aircraft Manual or Pilot's Operating Handbook
--Here you will find the operating limitations, performance capabilities,
normal and emergency procedures and many other performance suggestions.
Considerable testing has been used to develop the takeoff, landing, distance,
fuel consumption and weight/balance charts that insure safe operation. Knowing
how to use these charts and V numbers is an integral part of flight planning.
--Know your aircraft performance figures for the planned route.
--Plan into every stop and departure for delays.
--Review the airworthiness requirements as they apply to the route and time of
the flight.
9. Takeoff Planning
--The takeoff is the second most dangerous single phase of flying. The hazards
of the takeoff extend from the
inability or failure of the aircraft to perform, the deficiencies of the
airport, the obstructions beyond the runway
and the deficiencies of lighting or navaids used leaving the airport.
9.1Gross Weight
--The takeoff distance and climb capability is based on data from the POH.
Every increase in weight makes the
takeoff longer and the climb rate lower. Takeoff distance varies with the
square of the weight. Gross weight
is defined as the empty weight of the aircraft plus its useful load.
--Gross weight directly affects stall speed and takeoff velocity
--A 10 percent increase in takeoff weight gives:
--A 5 percent increase in the speed needed for liftoff
--A 9 percent decrease in acceleration capability
--A 21 percent increase in required liftoff distance
--Any weight above maximum allowed gross weight makes the aircraft unairworthy
--A pilot who ignores or is ignorant of his takeoff weight is negligent.
9.2Balance
--Any aircraft load must be arranged to fall within allowable center of
gravity limits
--An improperly loaded aircraft out of the C.G. limits will have poor handling
qualities.
--A forward CG can overload the nosewheel and cause an uncontrollable
condition
--A forward CG will decrease performance
--A forward CG will make the stall speed higher
--An aft CF will decrease static and dynamic longitudinal stability
--A stall with an aft CG will be sudden and violent
--An aft CG will dangerously affect recovery from a stall
--An aft CG will allow the elevator to overstress the aircraft and cause
structural failure
9.5 Pre-takeoff Check
--Time check
--Mixture check
--Flap check
--Transponder code in and on
10. Altitude
--Density altitude is the combined effect of pressure, altitude and
temperature.
--Aircraft instruments are calibrated under standard conditions for sea level
59 degrees Fahrenheit and 29.92
inches of mercury
--Air temperature and air pressure normally decrease with any increase in
altitude
--Density altitude is computed by correcting for pressure and temperature
variations from standard
--Higher density altitudes reduce engine power, propeller efficiency and wing
lift
--Density altitude can increase takeoff requirements by 25 percent for every
1000' of elevation
--POH takeoff charts require you to use pressure altitude and temperature
figures accurately.
--For best performance the air/fuel mixture must be properly leaned.
--Humidity affects engine performance more than anything.
--Add 10% to your performance figures in high humidity situations.
--At high densities use the same usual indicated airspeeds. True air speed
changes.
--Be sure to lean the engine for best power at density altitudes above 5000
feet.
--Plan for early morning and late afternoon departures.
--If ever in doubt about density altitude effects, stay on the ground.
11. Wind
--A headwind that is 10-percent of your liftoff speed will lower T.O. distance
by 19-percent
--The same amount of tailwind will increase T.O. distance by 21-percent
--Regardless of the wind the indicated airspeed for takeoff will be the same.
--Failure to select the proper runway is a major cause of takeoff accidents
--A 90-degree crosswind is effectively the same as a calm wind.
12. Runway
--Acceleration and braking is affected directly by surface condition
--Manual information is for level, dry and hard surfaces
--Any slope, gradient, composition or condition other than level, dry, and
hard makes a difference
--Runway gradient is maximum difference in runway centerline elevation divided
by its length
--Maximum runway grade and longitudinal grade change is 2 percent
--Runway length must be increased 20-percent for each 1 percent of upslope
--A one-percent upslope raises takeoff requirements by two to four percent
--An uphill into the wind takeoff is preferred to a down slope and downwind
takeoff
--Known effect of water, snow, sand, gravel, mud and grass is hard to
determine
--Each pilot must make his own decision but doubling is a minimum requirement
--Dry short grass on firm ground requires 107 percent of book figures.
--If power loss occurs on takeoff, land straight ahead
13. Ground Effect
--Drag is reduced close to the ground due to restricted airflow around the
wing.
--Ground effect makes it possible for an aircraft to lift off the ground and
not be able to climb.
--Leaving the ground in ground effect at too high an angle means that the nose
must lowered to regain
flying speed. With insufficient altitude to do this a crash is certain.
--It is best to lift off in ground effect and stay close to the ground to
accelerate
Spacing
Departure and Destination Checkpoints
A. Some compromise between a good checkpoint and equal spacing may need to
be made. Usually a slight change in distance can make this system work.
Likewise, it is important that the distances be measured only by using the
scale along the vertical lines of longitude. The checkpoints are not required
to be evenly spaced but it does make fuel and time estimates easier. It is
more important that checkpoints be easily identified.
B. Three identifiable elements to confirm point
C. Use a 60-degree+ VOR radial as backup for points. 60 degree angle or
higher.
D. Preferably on pilots side of course line
E. Located so as to account for visibility, speed and conditions.
F. Use VOR to/from departure/destination
--1. Account for altitude/range/obstructions
--2. Possible malfunction/ident required
--3. Double check OBS/compass/heading indicator
--4. Enter essentials on log and sectional
G. Fly an airport vicinity route. Avoid desolate areas.
H. Start with FULL tanks. Use the POH to figure fuel consumption.
Refuel to FULL at each stop and compare your estimates with actual. Start to
revise POH figures to fit actual fuel used as you make other flights until you
get more realistic estimates.
Cross-Country
Radio Preparation
X-Country preparation
Take a bottle of water (2) and some snack food. Except for STS there are no
places to eat planned. Willows is a possible if you must. Be sure to
amend/extend flight plan if you stop.
Take cell phone and call me when on the ground if you feel like it.
Write time on chart that you reach each checkpoint.
Don't be afraid to let go of the yoke and hold heading with rudder.
Hold chart so that the course line on the chart is pointed over the nose.
Fold chart so that it is about 8" wide with the course line in the
middle.
Hold chart up to check and write on it.
Looking down will cause you to descend and turn.
At each stop review the radio work for the next leg.
Write out flight plan forms ahead of time.

transponder code... write it down, say it back and put it into transponder.
Ident if asked.
You do not need to ask if you change course or altitude; just tell specialist
what you are doing. Any time you become concerned, just ask him to verify your
position and course. Make course corrections as he suggests. If he ignores you
for a period of time call and ask for 'radio check'. As you cross the hills
advise center that you are descending to 2800 and request frequency change. He
will tell you that radar service is terminated and to squawk
VFR (1200). Acknowledge with aircraft numbers.

Optional-
Enter VOR frequencies and radials to course line through nearby airports as
pre-planning for emergency diversion. Mark on sectional. Use large Z markers
along course line to put data.
--Make a scratch log of the checkpoints, distances, times
--The distance between checkpoints becomes greater as speed and visibility
become greater.
-- The distance between checkpoints is made identical beginning from your
destination. The distance to your first checkpoint will vary. Using this
system makes ETAs much easier to figure in your head.
--Next to each checkpoint make a large 'Z' with an arrow at each end. Write
the distance in each direction on the arms of the Z.
--Get as much essential information from your work sheets and logs on to the
sectional as is practical.
--Design your own log sheet using ideas from other sources. Your own log is
going to be more practical and useful when you have designed it to fit into
the way you do your planning and the information you will need. Like a
checklist this will take five revisions to develop a functional log. Start
with everything and then begin to eliminate.
-- Checkpoints, magnetic courses, radio frequencies, altitudes, and pattern
altitudes should be transferred to the sectional.
--You can adjust your ETA at every checkpoint. If the flight planned will not
work don’t hesitate to make changes.
--Know the airspace along and beside your route. Know the upper and lower
limits of any airspace you may be crossing over or under. Make airspace a part
of your planning.
--Make your checkpoints so that half checkpoints can be used if poor
visibility should occurs. You want to be able to see from checkpoint to
checkpoint.
--Know where the other airports are along your route.
--Know where your your ARrOW papers are in the aircraft.
--Know how to use to estimate distance and bearings on a sectional.
--Use power and re-trim when in slow flight.
--Use Post-Its to make finding your private pilot required logbook entries.
Make a scratch radio frequency card
--Orally review on a tape recorder communications with ground, tower, FSS,
radar, and flight watch
--Mark sectional to show initial call up points
--What if...plans
Mark sectional for fuel stops/tank changes, compass course pattern altitudes,
and required altitudes
--A. Plan for headwinds and higher fuel consumption
--Prepare a checkpoint checklist (see page three)
heck airport operation hours for lights, fuel, food, etc.
Night Before a

Preflight Weather
Weather does not care about your priorities or even your decisions. Collection
of weather information begins several days before the flight and continues
until reaching destination. Three days prior you get an Outlook Briefing from
either FSS or DUATs. Then comes the Standard Briefing a few hours before the
flight with an Abbreviated Briefing just prior to the flight. The pilot must
convert this information into a go/no go decision. Always wait for Briefer to
complete his order of information before asking questions.
Information from You
1. Aircraft identification and type
2. Your qualifications
3. Pre-solo as student with instructor
4. Student solo with/without instructor
5. Type of flight
6. Local
7. Between airports
8. Cross-country
9. Night
10. Departure point and route
11. Times involved (use local but learn to think Zulu)
12. Ask for 48 hour outlook for forward planning of next flight
NOTAMS
The Notice to Airmen Publications is now issued every 28 days. NOTAMS have
hundreds of obscure items that must be sifted to find what is important. What
is important to you is your departure point, route, and destination. Temporary
flight restrictions are important if they include your route. NOTAMs Ds and
FDCs will be published in the A/FD and in a biweekly Notices to Airmen.
NOTAMS can be added, changed, or deleted without notice. The NOTAM briefing of
a short flight to another airport will not protect you under FAR 91.103 for
your return flight. The FAA uses the potential endangerment factor to
determine grounds for a violation. If they want you, they can and will get
you.
Some briefings are more complete than others. If you know about the weather
and route you can get an abbreviated briefing that will take only a couple of
minutes. A standard briefing covers an entire region and can take fifteen
minutes or more. If you are going any distance beyond 50 miles you should ask
for NOTAM Ds. If you use DUAT get a route briefing since it will include NOTAM
Ds. Have the briefer check FDC NOTAMS for your route for flight restrictions.
To get a partial DUAT printout: High light, File print, selection
--Simply asking for Notices to Airmen (NOTAMS) is not enough.
--The information for all 5,600 airports receives full distribution.
--Yearly notices exceed 148,000 with 1,400 active on a given day.
--Taxiway information may be a NOTAM L for local distribution and runway
information may be NOTAM D for distant distribution.
--DUAT does not do NOTAM L.
--When a FSS briefer checks NOTAMs, he is referencing NOTAM Ds. for your
route. The NOTAM-D is for distant airports.
--NOTAM Ls are limited in FSS distribution and are not of 'vital' importance.
The NOTAM-L is for local airports.
--Flight Data Center NOTAMS (FDC) are regulatory. FDC NOTAMs are for navaids.
ATC Delays and flow control advisories
--FSSs do not provide published of special notices unless specifically asked
for them.

Abbreviated
Weather Briefing
1) Call FSS and ask for a briefing. One trick to know here is that unless you
know what magic words to say, you'll get a full briefing; this isn't
necessarily bad, but if all you want to know is one piece of data, it's
tedious. What you need to say is, "I'd like an abbreviated briefing; I
need current conditions at XYZ". This is an update of prior briefing
2) Get a (free) account on DUAT. Instructions how to do that are in the AIM.
This will give you access to all the same weather you would get from FSS. Many
people find this more convenient.
3) Look in the AFD -- there may very well be a local number you call to hear
the ATIS audio broadcast over the phone.

2. What about convection, Z-level, and fog?
3. What will warn you of worsening conditions?
4. What is my best escape route.
5. Mr. Briefer do you have any alternate suggestions?
6. Mr. Briefer, would you go flying with me?
Avoiding Convection
--Depart real early in the morning.
--Don't fly when thunderstorms exist at night.
--If caught, slow to Va, prepare cockpit and belts, lights on, wings level, no
autopilot, no turns, fly instruments

More
1. Briefing, synopsis, present, forecast, AIRMETS, SIGMETS, PIREPS, NOTAMS and
phone call to destination.
2. Don't fly into possible ice or deteriorating conditions.
3. Don't fly if you can anticipate being in unfamiliar regions.
Now That You
Have the Weather:
1. Is he weather above my 'personal' minimums?
2. How old is the weather information. Can I get some 'real-time?"
3. If the weather sours what are my alternatives. Always plan for alternatives
at both ends of the flight.
4. What winds can I expect and plan for takeoff, enroute, landing?
5. Do I have the pilot\aircraft capability to avoid problems?
6. Does the flight look like a 'good' one?
7. Once en route, how do things look?
8. VFR pilots have more difficulty with low ceilings than storms. Low ceilings
are sneaky. They don't become a problem until its too late.
9. For long flights you should record your ETAs in Zulu time since that will
enable you to compare the ETAs with the time of the weather forecasts.
Morning of a
Cross-Country
1. Call the FSS
Update weather information - get surface winds-NOTAMS. The briefer has a
limited time. He is required to follow a given procedure. Any mistakes will be
on the conservative side. You have to hear the rehearsed speech before a
meaning exchange of information can begin. The briefer gives you all the bad
news first. The general weather synopsis is of questionable value for local
flights. The FAA briefer is an aeronautical mother-in-law. Plenty of advice on
how to do something without having to deal with the consequences. A good
briefing depends on the skill and experience of the flight service specialist.
You are not required to be a weather expert. However, you must have the
ability to take the information presented and make the go-no-go decision. Very
often FSS information seems designed to keep us from flying instead of giving
information sufficiently complete, accurate and understandable enough to make
possible an intelligent decision. Even a student must learn to make
intelligent weather decisions.
Questions:
1. Describe your experience level and ask the FSS specialist, "If you
were at my level of experience would you go??"
2. Is the weather improving (we only fly into improving weather) at a rate
faster/slower than forecast?
3. Pilot reports?
4. Turbulence or winds of 30 kts?
5. Severe weather etc. Is there a SIGMETS/AIRMETS
6. Base go/no go decision on the actual conditions reported.
7. Leave yourself an optional way out.

E-6B
Dalton's original Model B calculator name was not part of the famous US Army
Air Corps "E-6B" designation. The "E" prefix followed the
arbitrary naming of the USAAC "E-1", an earlier Dalton circular
computer that ironically really was the Model B with additions. (Ten years
later, an "E-1" was a pair of flight trousers. What a fickle Army!)
The "6" was also more or less random.
And there was an "E-6A" prototype... I have a picture of it. Production (1940) models became the "E-6B". (Please note the hyphen position. Later copycat companies corrupted the name on purpose.)
One compelling theory is the above naming sequence was deliberately perused
to result in a useful inside joke: British navigation devices were (and are)
designated as "6B" items.
Kevin Darling
Flight Computer Historian
The E-6B was more created than invented by Phillip Dalton in the early 1930s.
It was initially called "The Dalton Dead reckoning Computer" . The
exact derivation of E6B is not known but the E-6B has become the generic name
for a vast number of similar devices, which include a circular slide rule and
a sliding wind angle ground speed plotter. The Dalton E-6B was developed from
a large shipboard device for handheld use aboard aircraft. My first E-6B,
which is still in the family, is from WWII and made of solid brass with
enameled engraving. A quality piece. Plastic E-6Bs became common later in the
war. Aluminum and cardboard came later as the E-6B became obsolete with the
advent of electronic E6Bs.
With practice the E-6B can be operated with one hand on both sides once the
forecast wind has been plotted. The E6B is a circular slide rule that has
numerous markings for changing from different forms of measurement. The
numerical scales allow relatively rapid solution of proportional problems. The
best use of the E6B can be achieved only when you fully understand how
proportions work. There are two time scales on the inner circles with
distance, and measures on the outside.
The simplest analogy is to use the sun, a man, his shadow, a tree, and its
shadow. These can be used to form a proportion since we know the shadow of a
man when made a ratio (fraction) to the height of the man will have the same
ratio as the (unknown) height of the tree to its shadow. There are 8 different
ways these numbers can be arranged as a proportion and 32 different
combinations to use three of them to find the fourth.
3 = 4 is a proportion made up of two ratios. They are equal when
6 8 the multiplied product of the diagonal numbers are equal.
3 x 8 = 24 and 6 x 4 = 24
Given any three of the numbers you can find the fourth by simply multiplying
the two diagonals and dividing by the remaining
number.
Given the 3, 8 and 6 we can find the four by (3 x 8)/ 6
To be able to use the E6B you must understand how these combinations
exist as time, distance, gallons, Every problem that gives three numbers even
with one of them 'understood' is a proportion solvable by the E6B. In addition
the E6B user must confirm that an answer is reasonable. The outer scale of the
E6B is a measure other than time. The middle scale is time in seconds or
minutes, the inner scale is time in hours/:minutes.
A problem that asks how far can you go at 90 miles an hour in twenty minutes
has two numbers given and that is the E6B speed index or 60 minutes. As a
beginner, you would do well to arrange the numbers as a proportion before
doing it on the E6B. As with the shadow analogy we started with, like or
related terms must either go one above the other or across the top or bottom
of the proportion. Any other arrangement will not give a 'reasonable' answer.
There are many ways this can be done but using the E6B format limits our
choices.
We have two time numbers. 60 minutes (1 hour) and 20 minutes. They are on the
middle scale. The distance of 90 miles 'goes' with the 60 minutes so the scale
is rotated until 90 is above the 60. The sought for missing number is a
distance on the outer scale above the 20 minutes.
When I was teaching an Adult Education ground school some thirty years ago I
always introduced the E-6-B by reviewing proportions and wind vectors.
I used a blackboard protractor and yardstick for the
wind-course-track-airspeed-groundspeed problem and solutions. I found that
doing this, as an introduction was valuable. The wind vector diagram makes it
possible to use the 'test of reasonableness' to your solution. It is possible
to get the wind arrow backwards on the E-6-B and get an unreasonable solution.
I also reviewed the making of proportions with the classes. You always have
three numbers to put in the proper
relationship in the __= __ equation. Placing them incorrectly will give the
incorrect answer. There are eight different ways to place the three numbers
that will give the correct solution. Knowing and practicing this on paper
makes the E-6-B more understandable.
Not teaching/knowing this basic system of navigation is a modern-day flight
training weakness.
More E-6B
The E-6B was more created than invented by Phillip Dalton in the early 1930s.
It was initially called "The Dalton Dead reckoning Computer" . The
exact derivation of E6B is not known but the E-6B has become the generic name
for a vast number of similar devices which include a circular slide rule and a
sliding wind angle ground speed plotter. The Dalton E-6B was developed from a
large shipboard device for handheld use aboard aircraft. My first E-6B, which is

The E6B is a circular slide rule that has numerous markings for changing from different forms of measurement. The numerical scales allow relatively rapid solution of proportional problems. The best use of the E6B can be achieved only when you fully understand how proportions work. There are two time scales on the inner circles with distance, and measures on the outside.
New E-6B Lesson:
Another area of mathematics you will be working with is proportions.
Sometimes a proportion is written as: A is to B as C is to D or A:B::C:D
It is easier to write proportions as a group of numbers again on a balance board. You need two numerators and two denominators. In a proportion problem you are given only three of the numbers and are asked to find the fourth. Sometimes, as in percentage, you are given only two of the numbers and are expected to know the third number (100) needed to do the mathematics required to find the fourth. In aviation the number 60 is shown as an index on the E-6B. Most of the operations on the E-6B are proportions and you can check the reasonableness of your soloutions very easily on paper.
Rule: a = c A single fraction can be called a
b d ratio. Two equal fractions on each
side of an equal sign are called a proportion.
You have done this many times in finding equivalent fractions.
1 = 3
2 6
Rule: the product of the numbers diagonal from each other across the equal sign must be equal for the fractions to be equal. 1 x 6 = 2 x 3
I'm going to take a moment now to show you that this single problem can be written eight different ways, as a proportion. The bold number is the number we need as an answer.
1 = 3 or 3 = 1 or 2 = 6 or 6 = 2
2 6 6 2 1 3 3 1
1 = 2 or 2 = 1 or 3 = 6 or 6
= 3
3 6 6 3 1 2 2 1
No matter how it is written the product of the diagonal numbers will always equal 6. Knowing this, if one of the numbers is missing we can find it. Pretend the darker number is missing in each problem above.
The purpose of this is to show you that, as long as related (having the same name) elements of a proportion or percentage problem are not placed on the diagonal, where the numbers go is not important.
Procedure:
On top of a line we put the two given. Using each of the numbers that are
diagonal from each other problems above we with a x (multiplication sign)
between them. Below the line we will put "Lonesome George". The number
without a companion diagonal.
2 x 3 or 6 x 1 or 1 x 6 or 2 x 3
1 3 2 6
1 x 6 or 2 x 3 or 1 x 6 or 2 x 3
2 6 3 1
What this does is make each proportion easy to solve.We can take the shortcut of canceling or go through all the steps of factoring, commuting, and making identity elements.

6. WHAT.IF PLAN
1. Don't get into the airplane without pointing the way you plan to fly.
Cross-country Lessons
--1.Flying through Travis uses 2/3 frequencies.
--2. Spacing checkpoints evenly is a compromise between availability and
visibility.
-- 3. A VOR behind a hill is no good.
--4. Pilotage works but only if you have good checkpoints and you stay on the
correct course.
--5. Dead reckoning works if you are lucky.
--6. Figuring the 45 entry is not easy now and it won't get any easier. Draw a
picture.
--7. You always want to fly too close to a small, strange field.
--8. Writing MH when you mean MC may be the source of a problem.
--9. When flying over a strange mountainous area you should have excess altitude
in order to see the lakes in the valleys.
--10. The lake you see does not 'have to be' the lake you want for a checkpoint.
--11. The radio of a helicopter on downwind and base can sound same as an
airplane but is much harder to see.
--12. Fatigue is insidious. Slow the aircraft to think things over when arriving
at a strange airport on a straight in approach. --13. A straight in approach is
harder to judge than a full pattern.
--14. Being low in the first place makes an airport even harder to find.
--15. Some airports require you to fly close to mountains for making the 45
entry. (Petaluma)
--16. When the aircraft makes strange noises...stop to check.
--17. Fly a larger pattern at strange airports. (Sonoma Valley) The problem of
trees is mostly psychological. Some airports are hard to find even when you know
where they are.
--18. You must make a note on your takeoff checklist to open a flight plan. You
must remember to note the time a flight plan should be closed. You can always
close early if you want to.
--19. You can fly through a Class D airspace just as easy as you can over it.
Just communicate.
--20. If you stop for fuel or a lunch add at least an extra hour to your trip
time.
--21. Accept long car rides and weather delays as a necessary factors in
becoming an old pilot.

Suggestions
Take
a bottle of water (2) and some snack food. Except for STS there are no places to
eat planned. Willows is a possible if you must. Be sure to amend/extend flight
plan if you stop. Take cell phone and call me if you feel like it.
--Write time on chart as you reach each checkpoint.
--Don't be afraid to let go of the yoke and hold heading with rudder while you
look at chart.
--Hold chart so that the course line on the chart is pointed over the nose.
--Fold chart so that it is about 8" wide with the course line in the
middle.
--Hold chart up to check and write on it.
--Looking down will cause you to descend and turn.
--At each stop review the radio work for the next leg.
--Write out flight plan forms ahead of time. Be sure to allow for time on the
ground

Ident if asked. You do not need to ask if you change course or altitude; just
tell specialist what you are doing. Any time you become concerned, just ask him
to verify your position and course. Make course corrections as he suggests. If
he ignores you for a period of time call and ask for 'radio check'.
As you cross the hills advise center that you are descending to 2800 and request

California to Illinois
Using the DigAV-Viewer and planner (Out of Business), I have plotted
my trip from Concord to P-ville on my handy-dandy new toy via airways. It tells
me that my route is 90 nm longer than a direct' line' route. Over forty of the
90 occur in Missouri from St Joe to P-ville. When I first ran it up, a notice
appeared to tell me that the route was 8.8% longer than the great circle. Route
via airways is 1675 nm which would make the great circle 1527.6 nm. or 147.4 nm
less. I ran a line between the two airports and it came up with 1540 nm with my
toy. This is a difference of 135 nm. Where you get 'killed' is the comfort and
fuel stops. P-ville is to be my sixth stop. Weather and all other factors
permitting, we sleep over in Nebraska and arrive Sat p.m. It's hard to ride the
jet stream in a C-172.
My toy will give all data required for a DUATS flight plan with long/lat,
distance, altitude, true/mag headings in both directions for each waypoint along
with a weather overlay. I presently have 38 waypoints but will probably cut some
corners bringing it down to the mid-twenties. I will be able to place a plane on
my route that will keep track of mileage flown and remaining as well as altitude
of the terrain below. I have printed out a route strip sectional map just in
case my laptop dies. I also have printed out all the frequencies from the
sectional legends so we can contact ATC when we want to. We have both a LORAN
and a GPS with up-to-date data bases. Food, water, emergency kit, flashlights,
clothes, basic tools, and still well under gross. Completely servicing aircraft
this week.
Money Well Spent for
Flight Planning
Not a flight plan form but a planner...I would call it a VFR version of the
Jeppesen and Flight Soft programs which cost hundreds of dollars more. I have no
commercial or other interest in this planner other than to say I was able to
keep my cockpit clutter down to a single sheet of paper and some WAC charts. I
demonstrated its capabilities at least forty times on my 3702 mile journey and at
the fly-in. I used a laptop but found it not functional in the cockpit. Laptop
lighting not bright enough.
On my entire flight to and from Pickneyville I used this new product to see if I
could recommend it to my students and the group. For $100 it does a great deal.
There is much I have yet to use like direct DUATS filing and weather overlay. I
have not entered my aircraft performance into the program but believe it can be
done. It comes as a CD with all 37 sectionals of the U.S. You have access to
airport information, airways, navaids, and special use airspace. It can be
updated free now but may cost in the future. I used AF/D's to get my radio and
airport information.
What it does:
Using the entire U.S. you can select any two points as departure and arrival.
Your straight line can be used like a rubber band by changing the cursor from a
hand (pointer) to a pencil to an eraser. The hand will drag any screen in any
direction and will identify any airway, airport, fix, or airspace while giving
sequence of leg, altitude, direction, and distance. Put the finger on any part
of the screen and it gives terrain altitude. Put it on an airway and it gives
the airway number, both true and magnetic direction for your direction of
flight, distance, NAVAID frequency and name.
The Pencil will stretch the course line any which way in an instant. It will not
move the map. The eraser will remove any fix on the course line causing the
course line to snap back to a direct route. Once you have selected your course
line, regardless of the length and direction, you can select several scale
settings to see detailed terrain, airports, airways, MOAs, or sectional displays
of any part of the route. You can read directly any and all of the information
that exists on a sectional. The program automatically overlaps the sectionals
from side to side and sectional to sectional seamlessly. Any flight can be made
and filed directly as a DUATs flight plan. The way I used it required that I
type out the plan as follows:

This meant that I needed only one piece of paper, 4 WAC Charts and four AF/Ds. I

Planning the Long
Cross-Country
The longer the flight the more comprehensive must be the planning. You
must plan for delays caused by weather, fueling, aircraft and personnel. Any
flight over 400 miles should expect to meet less than VFR weather, a fuel stop,
a kidney stop, or something unexpected. You should never fly far enough to have
fuel become a concern. With weather briefing weather up to six-hours old when
given, a flight of four hours really means you are flying with antiquated
weather information. This problem should be reduced by periodic contact with
Flight Watch.
The pilot should maintain a pilotage track on the charts and verify by use of
LORAN or GPS.
Radio contact should be maintained with ATC even if the flight is made below
radar coverage altitudes. You can always give position reports and then get back
on radar when possible.
Fuel Consumption Check
One very valuable planning process is to develop an actual fuel burn test at
a planned altitude. Load the aircraft to planned trip weight. This test is
relatively easy if you have the ability to select from multiple tanks. Do your
takeoff and climb to cruise altitude from one tank. Fly full cruise from another
tank. You might even fly a maximum range flight from another tank. I am presently
considering a flight to Anchorage, AK. As part of the planning we will takeoff
and climb on one tank to a cruise altitude of 7500 and then change tanks. By
checking the fuel use from the tank we will get an estimate of what to expect in
climb. Then again we will fly cruise at altitude while leaned for an hour on a
tank and use that consumption for our cruise estimate. Descents will vary
considerably so our conservative estimates will exceed required reserves.
For normal flights below 5000' where you climb at Vy and descend at cruise I
have found that I can just add five minutes to cruise time and fuel use.
Making an Airport
Compass Chart (Olympia, WA)
Beautiful! Butt the bottom of an old Seattle sectional up to the top a Klamath
Falls sectional and glue the edges together.
Use a string as a 10 to 12 inch compass to draw a circle the size of a medium
Pizza Use Olympia as the center. Paste the Pizza on to a piece of cardboard. Cut
out the Pizza to your favorite size.
You are doubly fortunate to have a VOR on the field. Also you have a compass
rose as well around the airport. Use the rose to locate all the radials every 30
degrees around the outer edge of the Pizza and write in the numbers. Mark the
10-degrees in between the cardinal headings.
You can string a rubber band through the center and tie it at the outer edge.
This will give you any magnetic course you need. With regular use the Pizza
directions will become second nature.
I use the backside to write out the radio procedures for any arrival in 30
degree slices of Pizza. I know what to say just by flipping the Pizza over. I
make a 15-mile call-up, a 5-mile callup and a 2-mile report that varies with the
active runway. All an unfamiliar pilot with this aid needs to do is know where
he is and flip over the Pizza and read the proper call-up.
It appears you have runways 27/9 and 35/17.
From the North
For 17...
--A 15 mile callup might be, "Olympia tower Cessna 1234X-ray Boston Harbor
at 2700 with Alpha request straight in 35 will report two-mile final."
(shoreline) for 9...
--A 15 mile callup might be, "Olympia tower Cessna 1234X-ray Boston Harbor
at 2700 with Alpha request left base for 9 will report two-mile base for 27...
--A 15-mile callup might be, "Olympia tower Cessna 1234X-ray Boston Harbor
at 2700 with Alpha request right base for 27 will report two-mile base for 35...
--A 15-mile callup might be, "Olympia tower Cessna 1234X-ray Boston Harbor
at 2700 with Alpha request direct entry to left/right downwind 35 will report
abeam the tower.
--The pilot 'wins' when the tower response is. "34x-ray approved as
requested" Try it, you'll like it. No punctuation in radio talk.
Quick Cross-Country
Planner
Some ways for planning a cross-country.
1. Check AF/D, or AOPA's Airport Directory) for information.
2. Use sectional charts to get a sense of the route, terrain and airspace
involved.
3. Select checkpoints for the route as near identical intervals as possible.
4. Use plotter to get true course for the route.
5. Using plotter, determine length of each segment.
6. Use POH to get airspeeds, time-to-climb, fuel burn and range.
7. Use E6B to calculate magnetic course. Wind will never be as forecast.
8. Draw magnetic course on sectional.

Opinion on
Cross-Country Planning
One of the things you may find as your experience grows is that you become more
adept at dealing with changes of mission, equipment, route, weather etc.
When I first learned to drive a car, I used to hate starting off on a journey
without knowing exactly where I was going to park at the other end. If I lacked
that knowledge, I would drive badly. It's not the sort of issue that crosses my
mind these days...
With the best will in the world, flying always seems to deny the opportunity to
plan exactly when one needs it.That used to stress me, as it appears to stress
you. Now I think (perhaps unwisely) that I'm better at understanding what's
important and what's not in the planning process, so I can adapt the process to
the time available. That's much more difficult when you're starting out.
I'm a great fan of the Graeme Edwards line "It's not the plan that is
important, it's the planning". Try planning
some routes, regardless of whether you intend to fly them or not. You may learn
a great deal.

Cross-Country Lessons
I have two types of dual cross-country flying lessons.
--Type one is where I assist in the planning and everything goes as planned.
--Type two is where the student does all the planning and I help by causing
problems to arise during the course of the flight.
Cross-Country Problem
Areas
Frequently problems are caused by:
--Selection of incorrect flight altitude
--Poor selection of visual checkpoints
--Poor cockpit organization of materials
--Failure to anticipate radio requirements
--Losing track of times between checkpoints
--Failure to locate checkpoints and verify route
--Difficulty planning strange airport arrival
--Knowing when and how to ask for ATC help
Planning the ETA
--Use your DME, GPS or ask ATC.. or…
--Take average cruise speed and divide INTO 60
--Have this as one of your constants on the lap board.
150 kts = .4; 10 miles takes 4 minutes
120 kts = .5 10 miles takes 5 minutes (Best IFR speed for learning if able)
105 kts = .57 10 miles takes just short of 6 minutes
100 kts = .6 10 miles takes six minutes
90 kts = .6.7 10 miles takes just short of seven minutes.
85 kts = .7 10 miles takes seven minutes
--By knowing this speed factor factor for your airplane you have all you need to
get ETAs.
--Timing is a good procedure for every phase of flight and approach
Student Effort
Everything you are doing is correct. ( Traditional flight planning with
deviation, variation, wind correction angle and ETAs) However, it is pretty much
an exercise in futility. No one flys within 3-degrees of an course/heading for.
more than two minutes.
Winds are never as forecast. True course is the line on the map. Magnetic course
is the direction you fly and altitude according to hemispheric rule. This is the
number to put on your sectional.
Look at my web site about how to select checkpoints backwards from your
destination in even spaces except for the first one on departure. Plan to be at
cruise altitude and speed. Fly to the first checkpoint and line up toward your
second checkpoint. Note actual wind correction required and time to checkpoint.
Fly a constant heading that takes you there. Adjust heading and time as required
for all subsequent checkpoints. Adjust ETA as required for remainder of trip.
Aiport arrival is on entering the pattern. Good enough for government work is
+/- three minutes.
GPS has made all such planning and figuring of value only as a back-up. Good
training when used in conjunction with moving map GPS.

A Better Method for Folding Charts
You might want to try the following link.
http://www.catskillhikes.com/mapfold.html
It shows the method described below.
First, unfold the chart and lay it flat. Now, fold the chart the long way. In
other words, fold it so it is still 3+ feet long, but only 10 or so inches
high. Still with me? Now, starting at the left side, fold the chart along the
creases in alternating directions. So, make the first fold "over",
the next fold "under", etc. If anyone is still with me, your should
now be able to open your chart to any location the same as you would open a
book. This is great for east/west flights. Like I said, it means you only get
one side of the chart...but if you buy two copies of the chart, then you
always have one ready to go for the side you are on. And it is SO much easier
to keep track of in flight.
Kevin Thorley
Allen,
Open an old sectional out until one flat sheet.
Suggest you run a sample marker line diagonally across the entire chart
Fold it into half lengthwise. Crease
Start at the left end and accordion fold all the way to the right side.
You can now use the folds like pages of a book to follow the line.
You never need more than two of the folds open at a time.
At the halfway point you flip the book over.
Try it, you'll like it.
To do a complete sectional you will need two of them. One for each side.

Teaching the E6-B
Hi,
My name is David Kwapinski and I am a aviation student at the University
of North Dakota. I am doing a presentation on the E6-B. I was wondering if you
could explain a little more on how it got the designation E6-B. Something about
the army? I am confused. If you could give me an explanation that would be
perfect. Thank you for your time. David Kwapinski
Dave,
Several years ago the son of the inventor filled me in a bit but I don't
remember the details. As best I can remember the inventor was in the Navy.
He did several versions until his final version he called the E6-B. I can't
recall just why it was called that. After the expensive brass ones came aluminum
and then plastic near the end of WWII. You should be aware that most of the
problems done on the time distance side of the E6-B are proportions. A person
who is uncertain in using the E6-B should work the proportions on paper to make
certain the reasonableness of his E6-B answer. A good way to introduce the E6-B
would be by displaying a series of proportion problems and their solutions. Then
follow up the process using the E6-B. True skill in using the E6-B is
demonstrated by using only one hand.
During the war I had a solid brass one that I gave to my son but it has since
disappeared. At one
point a marked improvement was made about 1980 by making some cutouts that
allowed you to
make 45 entries into patterns but the FAA thought it made the process too easy
and prohibited its
use while taking examinations. End of progress.
The wind side of the E6-B is best explained by drawing wind triangles. You need
to have a ruler,
protractor or plotter and a relatively large piece of paper. Since wind speeds
are in knots, it is best to do speed and distance in knots as well. Make a line
on the paper with every 1/16 inch as a nautical
mile. Select a direction and speed for the line. You could do all of these on a
sectional as well.
From the far end of the line use a protractor to draw the line that
proportionally gives velocity and
direction of the wind.
From the start of your airspeed line draw a line to the free end of the wind
vector. This line tells you
your ground speed and wind correction angle Odds are on that no one in your
group will have ever drawn a wind triangle so one instructional idea would be to
bring (borrow, steal) enough rulers and protractors for every two students. Set
up a problem that you already have drawn and solved for the class to do in
pairs. Walk them through it. One step at a time.
The value of this is that the E6-B can be done incorrectly several different
ways. Ability to draw and
understand the basics of a wind triangle give the pilot a test of
'reasonableness' to his E6-B solution.
You could set up a problem and ask each pair to time how long it takes to get
their first solution as
to ground speed and wind correction angle. Do three other problems and
have each pair try to
improve their time and accuracy with different winds and flight headings. You
may find that the wind triangle can be just as fast as the E6-B and puts the
problem on the chart at the same time.
Some examiners use this as a part of their commercial checkride.
What I am giving you is the basis for a presentation as I would do it to a group
of would-be pilots. I am showing you the basics needed to understand the E6-B.
It is a circular slide rule on one side and an overlay of a sectional direct
flight with wind on the other. Your presentation using how to solve proportions
and wind triangles will do more to explain the E6-B than actually using it. He
who teaches learns twice.
Plotter
The first aircraft plotter was invented by a Naval officer named Weems. He
adapted the much
larger shipboard plotter into a plastic model which was like a ruler with an arc
of 180-degrees
in the center. The ruler itself had measures for the WAC and sectional charts in
both nautical
and statute miles. A post-WWII improvement was to make a rotating azimuth dial
with arrows
indicating the route direction. Until recently all plotters were of a plastic
that would be destroyed
by heat. Protect any plotter from the sun.
After the expensive brass ones came aluminum and then plastic near the end of
WWII. You should be aware that most of the problems done on the time distance
side of the E6-B are proportions. A person who is uncertain in using the E6-B
should work the proportions on paper to make certain the
reasonableness of his E6-B answer.
A good way to introduce the E6-B would be by displaying a series of proportion
problems and their solutions. Then follow up the process using the E6-B.
True skill in using the E6-B is demonstrated by using only one hand. The
electronic E6-B need not be faster than the whiz-wheel.
Three related elements are always given with one element unknown. Think of a
tree (T)and its shadow (S) relative to a pole of known height. (H) find the
height of the tree. This is only one eight possible equations. See if you can
come up with the other seven. You always multiply the diagonals and divide by
the diagonal of lonesome George to get the value of lonesome George. T
equals_? (Lonesome George) Think 1/3 = 2/6 and arrange the numbers in
eight different but P H correct ways where the diagonals give the same
product.
The wind side of the E6-B is best explained by drawing wind triangles. You
need to have a ruler,
protractor (plotter) and a relatively large piece of paper. Since wind speeds
are in knots, it is best to do speed and distance in knots as well. Make a line
on the paper with every 1/16 inch as a nautical
mile. 16 per inch etc until you get one-hour's worth. Six inches = 96 knots TAS
Select a direction
and speed for the line as TC. (No variation or deviation) You could do all of
these on a sectional
as well. From the far end of the line use a protractor to draw the line that
proportionally gives velocity and direction of the wind. in knots and True
direction. Forecast winds are always True. Airport winds are always Magnetic. Do
all speeds in Knots From the start of your airspeed line draw a line to the free
end of the wind vector. This line tells you your ground speed and wind
correction angle. To this you must add/subtract variation and deviation.
Odds are on that no one in your group will have ever drawn a wind triangle so
one instructional idea
would be to bring (borrow, steal) enough rulers and protractors (plotters)for
every two students. Set up a problem that you already have drawn and solved for
the class to do in pairs. Walk them through it. One step at a time. The value of
this is that the E6-B can be done incorrectly several different ways. Ability to
draw and understand the basics of a wind triangle give the pilot a test of 'reasonableness'
to his E6-B solution.
You could set up a problem and ask each pair to time how long it takes to get
their first solution as
to ground speed and wind correction angle. Do three other problems and have each
pair try to
improve their time and accuracy with different winds and flight headings. You
may find that the wind triangle can be just as fast as the E6-B and puts the
problem on the chart at the same time.
Some examiners use this as a part of their commercial checkride. Important to
note that wind direction and velocity is NEVER as forecast. Be prepared to make
wind correction adjustments while en route..
