Preliminary - Subject to Change Without Notice
6. KAC 1052 Antenna Coupler Built-In-Test
The antenna coupler design incorporates provisions for
monitoring its own operation to detect any condition or
occurrence that the operator (a flight crew member) might
observe and interpret as a reason for requesting a
maintenance action.
These maintenance observations are stored in non-volatile
memory within the antenna coupler so they can be retrieved
with appropriate test equipment.
If the maintenance observation is serious enough to
indicate Antenna Coupler
communicated to the receiver/exciter for reporting to the
HF controller.
The BITE tests that shall be performed at system turn-on,
at pilot activation or continuously are summarized in
Table 1003.
