BEFORE USING YOUR E6B
Sporty's E6B Flight Computer requires three 1.5V AAA
batteries (not included) for operation. New batteries should
be installed in the battery compartment located in the top
rear of the computer. Make sure that battery polarity is
aligned correctly.
An opaque plastic film has been placed over the display
screen to protect your E6B during shipping. This film is
easily removed by peeling up one corner and pulling
gently.
This manual is designed to offer an introduction to the
operation of the E6B. For each calculation, a sample
problem has been given.
In order to save power, the display screen automatically
turns off approximately 4 minutes after the last keystroke.
However, the internal clock and timer will continue to run. If
the timer is counting down, it will not shut off for
approximately thirty minutes.
This multi-function computer is authorized and acceptable
for use during FAA and Canadian written tests. All memory
is erased by removing and reinstalling the batteries. NOTE:
This also removes clock settings. References: FAA
Advisory Circular 60-11B and FAA Order 8081D, Conduct
of Airmen Written Tests, April 10, 1989.

labels for specific problems. Below this are lines of text
representing display prompts, labels, and aviation
functions. Aviation functions available on the E6B will
remain visible whenever the power is on. The display

X
1 2 3 -
0 • =+
Your E6B performs all of the standard arithmetic functions
with the keys shown above, (addition, subtraction,
multiplication, and division). These functions as well as any
conversions can be performed at any time, even while
performing an aviation function. The E6B will display up to
six digits of the answer.
The =key should be used to compute any arithmetic
function
AVIATION FUNCTIONS
The aviation function menu is displayed on the bottom of
the screen. Your E6B will automatically save computed
values from one aviation function to another. To override
this option, key in new value when prompted. The E6B will
save true airspeed, groundspeed, time, and fuel per hour
functions. It will also save cumulative weight and balance
totals.

CONVERSIONS
Conversions are displayed above the appropriate key, and
are listed on the next page. All conversion functions are
keyed into the computer in the same manner. For example,
to convert decimal hours to hours, minutes and seconds:
Input 4 . 2 6 2 5
PressCONV
9
Press 6
The answer, 04:15:45, will appear on the display.
There are no conversion keys for kilometers to statute
miles or statute miles to kilometers. To convert from
kilometers to statute miles, first convert kilometers to
nautical miles, then nautical miles to statute miles.
To convert statute miles to kilometers, first convert from
statute miles to nautical miles, then nautical miles to
kilometers.
NOTE: Conversions may be made at any time and during
any other function. For example, if a calculation prompts
for temperature in Celsius and only Fahrenheit is available,
the Fahrenheit can be entered and converted without
exiting the calculation.

THE CLOCK FUNCTION
The E6B has three clocks that run simultaneously. They
are labeled as ZULU (#1), HOME (#2) and LOCAL (#3).
To display clocks (repeat to cancel):
Press CLK then press 0
11
To set 11:25:00 on ZULU clock:
Press CLK then press 1
Key in 11 then press :
Key in 25 then press CLK to start clock
To set hours for HOME and LOCAL clocks:
Press CLK then press 2(for HOME)
or 3(for LOCAL).
To synchronize minutes and seconds on clocks, press:
CLK 1 CLK

ADDING AND SUBTRACTING TIME
Time can be entered into the E6B in either decimal hours
or as hours, minutes and seconds. To enter in decimal
hours, simply key in a normal decimal number. For
example, entering 2.75 hours is the same as entering
02:45:00.
To key in time in hours, minutes and seconds mode, the
:key must be used. For example, to enter 3 hours,
14 minutes and 25 seconds:
Key in 3then press : and key in 14
Press :and key in 25
The display will read 03:14:25
To key in 5 hours even:
Key in 5and press :
The display will read 05:00:00
To key in 15 seconds:
Key in 0then press :twice and key in 15
The display will read 00:00:15
Time can be added in either mode; times from different
modes can also be added without converting.
For example, to add 3.45 hours and 2:45:00:
Key in 3.45 and press +
Key in 2:45 and press =
The display will read 06:12:00.
12

TIMER FUNCTION
The timer can be used in either a count down or count up
mode.
To enter TIMER mode, press TIMER
Once in TIMER mode, the TIMER key acts as a
start/stop button. The timer is set to count up.
To change counting direction, press CONV TIMER
The timer can be cleared by pressing:
C CLK TIMER
To input a time other than 00:00:00:
Press Cthen input a time in hours, minutes,
seconds (HMS) or decimal format then press CLK
TIMER . To count up, press TIMER
To count down, press CONV TIMER
Upon reaching zero in count down mode, the timer will
count time since zero was reached. To denote this, a
negative sign will appear to the right of the timer. The
count down timer can be used as a reminder of when to
switch fuel tanks, to fly a non-precision approach (LEG
TIME function) or measuring ground speed from one
checkpoint to another checkpoint (GS).
Any function requiring time to be entered, the timer may be
used by pressing TIMER ENTER when prompted
for time. The timer can be set to 00:00:00 or another time
and then count up or down in these calculations.
Activating the count down timer will keep the screen from
turning off until approximately thirty minutes without use.

PRESSURE AND DENSITY ALTITUDE
(P-D/ALT)
This function will compute the pressure and density altitude
given the indicated altitude, barometric pressure (altimeter
setting in inches), and true temperature in Celsius. In this
example, indicated altitude is 10,000 feet, the barometer is
29.94 inches, and the temperature is 5°C.

Since it is one of the most important aviation calculations,
this function flashes on the main menu when the computer
is turned on. It calculates fuel requirements given time and
fuel per hour consumption. In this example, flying time is 3
hours 15 minutes and fuel per hour consumption is 14
gallons.

CROSSWIND, HEADWIND AND TAILWIND
(X/H-WIND)
This function computes the crosswind component and
headwind or tailwind component given wind direction, wind
speed and runway number. In this example, the wind is
from 270° at 20, and the runway number is 30. Note that
the runway number, not heading, is asked for, and
therefore 30 should be entered, not 300.
