the exception of some mamud switch settings, such as
those on the SHC, which are not software controllable.
BIT execution can be either automatic or operator
initiated. Upon application of aircmtl radar power, ORT
is automatically initiated. The RIO either switches the
SHC from OFF to CMPTR (to start CDM execution),o r
STBY or XMIT (to start ORT execution). Afler powerup,

CDM/ORT is not aborted, ORT requirea nominally 3.5
minutes to complete and CDM requims nominally 2.5
minutes to complete.

Figure 38-25. Test-m-ProgressD isplay
The test-m-progressd isplay is presentedo n the TID
(seeF igure 38-25).T he WRA unit designatorsb link for
those units that are undergoing test. Approximately 3
minutes after radar turn-on, an XMT acronym at the top
of the TID prompts the RIO to switch to XMT, if the
SHC switch is in STBY. The RIO has 25 seconds to
respond Failure to do so within the allotted time results
in bypassing the system transmitter test. If the RIO responds
in time, the transmitter test is executed and the
transmitter subsystem unit group blii, indicating that
testing is in progress. At the completion of ORT (and
CDM) DhL4 is presented on the TID. This display pmvides
an evaluation of the working status of the tactical
modes. If the RIO desires more detailed information, the
maintenance display can be selected by depressing the
DD pushtile adjacent to MAINT DEP. This display
provides test fail or pass status, the detected malfunctioning
WRAs, and the associated DPs. DPs provide
specific detailed information on the faults detected
within a particular unit. In order to get back to the DMA
display, the pushtile adjacent to MAINT DISP is
reselected.
38.5.2.1 BIT Display Formats. BIT displays provide
feedback on test progress, required RIO actions,
pass/fail status, detected faults, and maintenance action
recommendations. These displays include the test in
pmgress, BIT menu, degradedm ode assessmentm, aintenance
display, test target, CM, TCS test, DD BIST,
displays test (static and dynamic), and special test.
38.5.2.1.1 Test-in-Progress Display. The testin-
progressT ID display is presentedu pon initiation of
ORT, CDM, or IRT (see Figure 38-25). This display
provides status on WRA testing progress, OBC, continuous
monitor failures, missile channel selection, and
the DPs from previous ORT, CDM, IRT, or CM tests (if
power was not interrupted to the radar). The appropriate
WRA reference designators blii for units undergoing
test.W RA designatorsa ndt heir correspondingc ommon
names are listed in Figure 38-26.
At the completion of ORT, CDM or IRT, the degradedm
ode assessmenfto rmat (describedin paragraph
38.5.2.1.3) is displayed on the TID.
38.5.2.1.2 BIT Menu Display Format. The DD
BIT menu is presented at the completion of ORT or
CDM, and provides allowable RIO BIT test selections
(see Figure 38-27). The RIO can initiate the following
tests t?om this menu: displays test, radar test, TCS test,
special test, or test target. These tests are initiated by
depressingth e pusbtile adjacentt o the desiredt estn ame
on the DD. A highlighted box appears around the test
name on the DD to indicate that a test has been selected.
Tests cannot be initiated concurrently.
