Depress KYBD key. (SELECT field blinks.)
Enter Y (yes) for mode selection. N may be entered to
arm the system but without entering the Route-Se-
quence-Consecutive mode, or to exit the Route-Se-
quence-Consecutive mode if the system is currently in
that mode. An entry of Y or R indicates a choice of Y-flying
in the forward order, or R-flying in reverse order.
NOTE
If an entry is changed after Y or R is entered
for selection, and N must be entered for the
selection then it may be changed to Y or R.
The sequence must be flown from the begin-
ning waypoint. No target destinations or des-
tinations with target motion may be included
as Route Sequence Consecutive waypoints.
f. Procedure for Displaying Distance/Bearing/Time
Information.
(1)
Set MODE switch to MGRS (LAT/LONG or
GPS LDG may also be used).
(2)
Set DISPLAY switch to DIS/BRG/TIME.
(3)
Observe that the distance-to-go in kilome-
ters (to the fly-destination), bearing, and time-to-go ap-
pears on the bottom two lines of the display. (Distance is
in nautical miles when MODE switch position is LAT/
LONG.) Bearing-to-destination is displayed in hours,
minutes, and tenths of a minute.
(4)
The display of the second line depends on
the current steering mode as follows:
(a)
Direct-To Steering (default): Fly-to des-
tination number and ICAO identifier are displayed. Ex-
ample: 58:BANDO
(b)
To-To Steering: TO-TO-:XX TO YY
where XX is the To-To start-of-leg destination number,
and YY is the To-To fly-to destination number.
(c)
Route-Sequence Steering (both con-
secutive and random): RT-RANDOM: XXTOYY where
XX is current Route-Sequence fly-to destination number,
and YY is the next destination number in the sequence.
Approximately 10 seconds before overflying the fly-to
destination, the system automatically pickles to the next
destination, and the new fly-to number blinks for 10 sec-
onds then stops blinking.
g. Procedure for Displaying Present Position and
GPS Altitude
(1)
Set the MODE switch to MGRS (LAT/LONG
or GPS LDG may also be used). Set the DISPLAY switch
to PP and observe present position display.
(2)
To display present position variation and
GPS altitude depress the ENT key. Present position vari-
ation may be entered by depressing the KYBD key to
select the variation field. A variation is entered and the
ENT key is depressed.
h. Target Store (TGT STR) Operation
Two methods may be used for target store operation.
Method 1 is normally used when time is not available to
preplan a target store operation. Method 2 is used when
time is available and it is desired to store a target in a
specific location.
Method 1 (uses location 90-99)
(1)
Depress the TGT STR key while flying over
target.
(2)
Present position and variation are automati-
cally stored in the target destination location which was
displayed in the target store field immediately prior to
depressing the TGT STR key.
Method 2 (uses locations 00-69 and 90-99)
1. Set MODE switch to MGRS or LAT/LONG
position, depending on coordinate from de-
sired.
2. Set display switch to WP/TGT position.
3. To access P, depress the LTR LEFT key
followed by the 6 key. Another way to ac-
cess P, is to display waypoint 99 then de-
press the INC key or display waypoint 00
then depress the DEC key.
4. Depress KYBD key when overflying poten-
tial target. Observe that display freezes and
kybd is displayed in the bottom right corner
of the display indicating keyboard mode.
The destination number is now under key-
board control indicated by a blinking field.
CAUTION
Do not depress ENT key while destination
is set to P.
5. If it desired to store the target enter the two
digit destination number and depress the
ENT key.
6. If is not desired to store the target , set the
DISPLAY switch momentarily or perma-
nently to another position.
i. Procedure for Entering Landing Mode
(1)
Set the Fly-to destination by setting the DIS-
PLAY switch to either XTK/TKE/KEY or DIST/BRG/
TIME. Directly enter the two digit destination number or
use the INC or DEC keys.
(2)
Set MODE switch to GPS LDG.
(3)
The DISPLAY switch continues to function
as before. To switch between metric and English units,
depress the ENT key.
