l JTIDS manually initiated BIT shall not be
performed without a fault indication by
either background BIT or startup BIT.
Manual BIT operation with no posted
fault(s) can give false indications of
JTIDS WRA/SRA failures.
3. Select JTIDS mode - DATA XL or NORM.
This will power up the JTIDS part of the system.
19.6.4.2 Initialization
1.. MFD3 - Select JTIDS own-aircraft data page
and ACK all computer messages.
2. DEU - Select DOWNLOAD then ENTR (initiates
MCS download of DSU JTIDS load to the
JTIDS system).
3. MFD3 - Verify DSS LOAD on own-aircraft
data page changes to IN PROG (2 to 3 seconds)
and finally to OK (6 to 8 seconds).V erify noneo f
the following JTlDS computer messages are displayed.
a. JTIDS NOT AVAIL - Verify JTIDS is
powered up and communicating on the bus.
b. NO LOAD -NEED DSS - Verify DSU installed
and powered up.
c. NO LOAD - DSS FAIL - DSS fail; try to
clear failure.
d. LOAD ERROR- JTIDS - Bad JTIDS load;
net operations will be effected.

4. MFD3 (own-aircraft data page) - Verify correct
crypt0 period. To change crypt0 period:
a. DEU - Select JTIDS COMM page, toggle
CRYPT0 option switch to 0 or 1, then press
ENTR.
b. MFD3 (own-aircraft data page) - Verify
crypt0 period selected.
c. JTIDS MODE switch - Cycle MODE
switch from NORM or DATA SIL to STRY
then back to NORM or DATA SIL.
Note
Cycling the JTIDS MODE switch is required
to direct the DPG to accesst he desiredc rypt0
variables. If the MODE switch is not cycled,
the DPG will continue to access the previous
crypt0 variables while displaying the desired
crypt0 period on the own-aircraft data page
and net entry will not occur.
19.6.4.3 Synchronization. Thefollowingstepsare
required to synchronize JTIDS with the network.
1. Verify/select desired JTIDS antenna.
2. MFD3 (own-aircrattdatapage) - Verify JTIDS
time is i6 seconds of net time (GOES time, NTR,
or any participant in the net).
3. DEU (time entry, JTIDS COMM page, TIME
pushbutton) - Enter hours, minutes, seconds,
and select ENT.
4. MFD3 (own-aimmft data page) - Verify correct
time.
5. MFD3 (own-aircraft data page) - Verify NET
ENTR - NS (net entry not started), IN PROG
(attempting sync or course achieved), OK (synchronization
complete/fine synchronization
achieved).
6. DEU (net entry, JTIDS MODE page) - Press
NET ENTR pushbutton and ENT.
7. MFD3 (own-aircraft data page) - Verify NET
ENTR - IN PROG. Changes to OK synchronization
complete (3 to 5 minutes normal mode, 7 to
10 minutes data-silent mode).
Note
Course sync can be verified by verifying
the display of PPLI messages on TSD,
TID, JTIDS data readout pages, or IRST
summary page. JTIDS must be selected on
the DATA LINK control panel to process
PPLI messages.
8. DATA LINK control panel - Verify/select
JTIDS for JTIDS tactical functions.
19.6.4.4 JTIDS Shutdown. If network operations
are anticipated within 24 hours:
1. JTIDS MODE switch - STBY.
If network operations are not anticipated within 24
hours:
1. JTIDS MODE switch - OFF.
Note
Under no circumstances should the JTIDS
MODE switch be left in DATA SILENT or
NORM for greater than 90 seconds without
electrical power on the aircraft. Doing this
will deplete the battery and require it to be
charged by maintenance personnel. Clypto
variables cannot be accepted or maintained
if the battery is depleted.
19.7 IN-FLIGHT VISUAL COMMUNICATIONS
Communications between aircraft are visual whenever
practicable. Flight leaders shall ensure that all pilots
in the formation receive and acknowledge signals
when given. The visual communication chapters of
NAVAIR OO-80T-113t,h e Aircraft Signals NATOPS
Manual, should be reviewed and practiced by all pilots
and RIOs. Common visual signals applicable to flight
operation are listed in Figure 19-14.
19.8 GROUND HANDLING SIGNALS
Communications between aircraft and ground personnel
are visual whenever practicable, operations permitting.
The visual communication chapters of
NAVAIR 00-8OT-113 should be reviewed and practiced
by all flightcrew and groundcrew personnel. For ease
of reference, visual signals applicable to F-14
deck/ground handling arelisted on Figure 19-15. During
night operations, flashlights or wands shall be substituted
for hand and finger movements. Refer to NAVAIR
OO-80T-103fo r aircraft arming and sating hands ignals.
