BEFORE USING YOUR E6B-F

Sporty's E6B-F Flight Computer requires two 3V Lithium

batteries model number CR2032 Sporty’s Product number

2098A (not included) for operation. New batteries should be

installed in the battery compartment located in the lower 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-F 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-F. 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.

SPECIAL FUNCTION KEYS

ON Turns power on and resets E6B-F to main menu.

OFF Turns display screen off.

TIMER Starts and stops timer function.

ENTER Selects menu function and enters data input.

=Totals regular calculator functions.

CONV Converts keys to alternate functions.

CLK Controls display and setting of clocks.

C Clears current input line.

Controls function menu cursor. The function on

which cursor is located will blink. Arrows return

computer to main menu when in an aviation function

mode.

+/- Changes negative to a positive and positive to a negative.

A negative number will be denoted by a minus sign near

the upper right hand corner of the number. For example,

to input -17:

Press 1 7 +/-

And the screen will read 17.-

ARITHMETIC FUNCTIONS

7 8 9

4 5 6 X

1 2 3 -

0 • =+

Your E6B-F 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-F 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-F will automatically save computed values

from one aviation function to another. To override this option,

key in new value when prompted. The E6B-F will save true

airspeed, ground speed, time, and fuel per hour functions. It will

also save cumulative weight and balance totals.

CONVERSIONS

Conversions are displayed above the appropriate key. All

conversion functions are keyed into the computer in the same

manner. For example, to convert decimal hours to hours,

minutes and seconds:

Input4 . 2 6 2 5

Press CONV

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.

CLK CLK1

CLOCK FUNCTION

The E6B-F 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

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:

ADDING AND SUBTRACTING TIME

Time can be entered into the E6B-F 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.

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 again

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
