SPZ--8000 Digital Integrated Flight Control System
TST (Test) -- The TST position selects the radar test mode. A test
D
pattern is displayed to verify system operation. TEST is displayed
in the mode field. For test patterns and fault code descriptions, see
the self--test section of this appendix.
UNLESS THE SYSTEM IS IN FORCED STANDBY, THE
TRANSMITTER
MICROWAVE ENERGY IN TEST MODE. REFER TO THE
MAXIMUM PERMISSIBLE
PARAGRAPHS IN THIS APPENDIX, AND FEDERAL AVIATION
ADMINISTRATION (FAA) ADVISORY CIRCULARS, TO PREVENT
POSSIBLE DAMAGE TO THE HUMAN BODY.
FSBY (Forced Standby)
Forced standby is an automatic, nonselectable radar mode. As an
installation option, the system can be wired to the weight--on--wheels
(WOW) switch. If this is done, the RTA is in forced standby mode when
the aircraft is on the ground. In forced standby mode, the transmitter
and antenna scan are both inhibited, the display memory is erased, and
FSBY is displayed in the mode field. When in forced standby mode,
pushing the range select buttons simultaneously restores normal
operation.
The forced standby mode is a safety feature that inhibits the transmitter
on the ground to eliminate the X--Band microwave radiation hazard.
FORCED STANDBY MODE MUST BE VERIFIED BY THE
OPERATOR TO ENSURE SAFETY FOR GROUND PERSONNEL.
