How to use the E6B Flight Computer dial
When doing calculations, the rotating dial will represent
the time and the face/dial the units (distance, pounds,
gallons, etc.)
¤ Let’s try an example:
You’re in your car on the freeway traveling at 60 miles-
per-hour. You’ve been traveling for 2.5 hours. How far
have you gone?
¤ Solution:
Turn the rotating dial so that the red numeral on the
dial (which represents 1 hour) is directly over the “60”
indicator triangle on the face at 12 o’clock (which
represents the 60 miles traveled in 1 hour). Directly
below the numeral 25 (2.5 hours) on the dial you should
see the numeral 15 on the face. The 15 represents the
significant digits of the answer and we must decide
whether there should be none, 1 or 2 zeros after the 15.
10
The E6B Flight Computer is based on the principle of the slide rule. The unit of measurement is the base
10 logarithms (log10). These instructions cover only the basics of using the E6B Flight Computer
dial/slide rule. A more complete description may be found in your public library or on the internet.
How to read the scale
The most important technique to master is reading the scale. The numbered tick marks can represent a
range of values. For example, on the scale on the face of the watch, the numeral 30 to the left of the
letters “NAUT” can represent 30, or 300 or 3000 or 3.0. The nine tick marks between the 30 and 35 each
represent 1/10 of the distance between 30 and 35, or 300 and 350, or 3000 and 3500, or 3.0 and 3.5. So
for 3.0 and 3.5 each one of the tick marks represents .05; for 30 and 35, 0.5; for 300 and 350, 5; for
3000 and 3500, 50. You can see it is important that you keep track of the range that each interval
represents.

You can probably guess how many, because 15 miles in 2.5 hours is obviously too little and 1500 is
obviously too much. So the answer must be 150 miles.
¤ Let’s try another example:
Again, you’re going down the freeway at 70 miles-per-hour. You’ve been traveling at that speed for
110 minutes. How far have you traveled?
¤ Solution:
Turn the dial so that the numeral 60 (which represents 60 minutes) on the dial is right above the
number 7 (which represents 70 miles-per-sixty minutes). Now find the numeral 11 on the dial and
look directly below it on the face. You will note that the 11 is between the numerals 12 and 13 on the
face. We must now interpolate. First we must decide whether the numerals 12 and 13 on the face
represent 12 and 13, 120 and 130, 1200 and 1300, etc. It’s obvious that 12 is too little and 1200 is
too big, but sometimes it’s not so obvious. So here’s another method.
At 70 miles-per-hour (70 miles in 60 minutes), you would
have to travel over 14 hours to go further than 1000 miles.
14 hours is 840 minutes. So the answer must have more
than 2 and less than 4 digits. In other words, it must
have 3 digits until you get above 14 hours or 840 minutes.
After using the Flight Computer for a while these
mental estimates will become second nature (i.e. intuitive).
Now that we’ve done the mental calculation, we know that
the answer must have 3 digits. Therefore 12 must
represent the number 120 and 13 must represent the
number 130. Since there are nine ticks between the 12 and
13, there are ten divisions between them. Since they
represent the difference between the numbers 120 and
130, which is 10, each tick must represent 1. Since the
numeral 11 on the dial is above the eighth tick after

12.

the 12 on the face, it represents 8. Therefore the distance traveled in 110 minutes at 70 miles-per-
hour is 120 + 8 or 128 miles.
How to calculate distance and fuel usage
Now that you know a few of the basics, you can start using the Flight Computer to estimate your
distance or fuel usage in relation to time. Simply select the numeral on the dial that represents the
time interval and set the dial so that number is directly above the numeral on the face represents the
number of miles, kilometers, nautical miles or pounds of fuel traveled or used in that time period. Then,
as time passes, you locate the lapsed time on the dial and look directly below it for the approximate
distance traveled, fuel usage, etc. How to convert basic units
The Flight Computer is provided with red arrows on
the face for converting to and from nautical miles,
statute miles and kilometers. The Red arrow above
the “A” in “STAT” on the face is for statute miles.
The red arrow above the “U” in“NAUT” on the face is
for nautical miles.
The red arrow above the “H” in MPH is for
kilometers.
To convert, for example, 13 KM. to statute and
nautical, move the dial so that the numeral 13 on
the dial is directly above the red arrow over the
“H” in “MPH” on the face. The statute miles in
13 KM. is found on the dial directly above the red
arrow above the “A” in “STAT” on the face, which is
the numeral 8.1.
Thus 8.1 statute miles equals 13 KM. If you look
directly above the red arrow above the “U” in “NAUT”
you will see the numeral 7.05. This is the number of
nautical miles in 8.1 statute miles and 13 KM.

The example below converts 20 gallons of oil (petroleum) to pounds. The Conversion Table shows
1 gallon = 7.35 pounds, so setting the on the dial over 7.35 and looking under 20 on the dial
shows 147 pounds on the watch face scale.
10
NOTE!
Use the Flight Computer only to
estimate fuel usage and travel distance.
Do not rely on it for navigation purposes.
Its purpose is to allow you to keep track
of approximate fuel usage or distance
traveled over time and to estimate
equivalent kilometers, statute and or
nautical miles. Any other use is outside
the design parameters of the Flight
Computer and is not recommended.
Other conversions
You can also do other conversion calculations on the Flight Computer. You can, for example, convert
pounds of aviation gasoline, kerosene, or JP-4 to gallons. You can also convert from gallons to pounds.
Simply move the dial so that the is over the numeral on the face that represents the number of 10
pounds in 1 gallon of that type of liquid (see the conversion table on next page), find the number of
gallons you’re converting on the dial and look directly below that at the corresponding number on the
face. That is the number of pounds!
