(3) Depress the ENT key. Observe that a menu
of special steering functions appears.
(4) To select the Route-Sequence-Consecutive
display depress key 3. Observe that RT SEQ CONSEC
now appears in the display, followed by starting and ending
destination numbers, and mode selection.
(5) To enter keyboard depress the KYBD key.
(START field blinks.) To enter starting destination 32 depress
leys 3, 2.
(6) Depress KYBD key. (END field blinks.) Depress
keys 3, 5 to enter destination 35.
TM 1-1520-240-10
3-3-31
(7) 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-Sequence-
Consecutive mode, or to exit the Route-Sequence-
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 beginning
waypoint. No target destinations or destinations
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 kilometers
(to the fly-destination), bearing, and time-to-go appears
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 destination
number and ICAO identifier are displayed. Example:
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 consecutive
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 seconds
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 variation
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 automatically
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 desired.
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 access
P, is to display waypoint 99 then depress
the INC key or display waypoint 00
then depress the DEC key.
4. Depress KYBD key when overflying potential
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 keyboard
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 permanently
to another position.
i. Procedure for Entering Landing Mode
(1) Set the Fly-to destination by setting the DISPLAY
switch to either XTK/TKE/KEY or DIST/BRG/
