DMA is to give the RIO an evaluation of the working
status of tactical modes. An acronym for each mode is
displayed on the TID and a pass (J), fail (X), degraded
(O), or unevaluated indication is presented with each
acronym.
The symbols that appear on the displays and the corresponding
modes or fonctionnamed for thebasic DMA
arc as follows:
1. PDS - Pulse Doppler search.
2. RWS -Range while search.
NAVAIR 0%F14AAD-1
3. TWS -Track while mm.
4. PDSl-r -Pulse Doppler shlgle-target uack
5. MRL - Manual rapid lock-on.
6. PAL - Pilot automatic lock-on.
7. PSI-r-Pulse singl&tget track.
8. RGSTT - Range-gated sin@etar@t track.
9. VSL - Vertical scan lock-on.
10. PLM - Pilot lock-on mode.
11. PS - Pulse search.
‘2. GM-Ground map.
13. AGR - Air-to-ground ranging.
14. BIT-Built-m test.
For a more detailed description of the pass/fail status
of ORT, CDM, or IRT, the maintenance display format
(described in paragraph 38.5.2.1.4) is called up on the
TID by depressing the pushtile adjacent to MAINT
DISP (on the DD BIT menu). The DMA display format
is restored by reselecting the pushtile adjacent to
MAINT DISP.
Note
After a tactical mode is entered, the DMA
display format cannot be restored.
38.5.2.1.4 Maintenance Display Format. The
maintenanced isplay is obtainedb y depressingt he DD
BIT menu pushtile adjacent to MAINT DUP. It can be
selected during displays test, a tactical radar mode, or
special test. It can also be obtained bytransitioning from
the DMA display (described in paragraph 38.5.2.1.3).
The maintenance display provides test pass or fail
status to the RIO. If no faults are detected, an RDR
PASSED indication is displayed near the top of the TID,
no WR.4 designators are displayed, and a checkmark
appears adjacent to the appropriate test (see Figure
38-29). If a failure is detected, an RDR FAILED indication
is displayed near the top of the TID, and the
WRAs recommended for replacement, along with the
associated DPs, are displayed on the TID (see Figure
38-30). The WRA designators and their corresponding
common names are listed in Figure 38-26.

Detected failures are isolated to a maximum of six
WRAs. A maximum of 10 DPs are displayed adjacent
to the test that was performed: ORT, IBIT (radar test,
displays test), or CM.
Values for DS and PP for HPRF and LPRF modes
are. displayed on the TID along with the AIM-54 or
AIM-7 channel being tested.
38.8.2.1.8 Test-Target BIT. The test-target tiction
is an end-to-end test of the radar system, initiated
and evaluated by the RIO. It can be used to quickly
verify that the radar system is capable ofdetecting, pmcessing,
and displaying reasonably sized targets. It is
available in and can be used to check the operation of
I low, medium, or high PRF tactical modes.
To initiate the test target, the DD MFK pushtile is
used to select the BIT menu. The test target is selected
by depressing the button adjacent to TEST TGT. The
test-target menu is displayed on the DD (see Figure.
38-31). The test target can be injected in two places
dependingo n RIO switch activation. By depressingth e
pushtile adjacent to RDM TGT, the target is injected
through the radome radar test horn and is received and
processedth rough the antennaa rmy. By depressingth e
pushtile adjacent to RCVR TGT, the target is injected
directly through the receiver, thus bypassing the antenna.
To terminate test target BIT, the pushtile adjacent
to the enabled test target injection location is reselected.
The RIO can now select any tactical mode by de
pressing the DD pushtile for the desired mode. The radar
test target will be processed and displayed on the DD
and TID just as any newly detected target in the mode
