ERR# TEXT MESSAGE(S)
DESCRIPTION OF ERROR
46 Trim mon 5 -- MET failed
Preflight test failed due to improper response of the MET latent switch monitor.
The monitor did not detect a DN switch in the absence of an ARM. This indicates
a probable failure in the MET monitor of the flight computer. Manual Electric
Trim and Autotrim operation is disallowed.
47 Trim mon 6 -- MET failed
Preflight test failed due to improper response of the MET latent switch monitor.
The monitor failed a valid trim down command with ARM. This indicates a probable
failure in the MET monitor of the flight computer. Manual Electric Trim and
Autotrim operation is disallowed.
48 Trim mon 7 -- MET failed
Preflight test failed due to improper response of the MET latent switch monitor.
The monitor did not detect and ARM switch without an UP or DN input. This indicates
a probable failure in the MET monitor of the flight computer. Manual Electric
Trim and Autotrim operation is disallowed.
49 Trim voltage over certified value
Preflight test failed due to improper motor drive voltage from the trim servo.
Check that trim servo is proper flavor for the certification. Manual Electric
Trim and Autotrim operation is disallowed.
50 Trim voltage below min
Preflight test failed due to lack of response of the trim motor voltage. This
indicates a possible failure of the trim servo or interconnect. Manual Electric
Trim and Autotrim operation is disallowed.
51 Trim servo disable failed
During preflight test, the trim servo disable output did not inhibit the trim
servo. This preflight test step fails the trim monitor, outputs maximum trim
command, and verifies that the trim voltage is less than 2.5 volts. Manual
Electric Trim and Autotrim operation is disallowed.
52 Failed trim interrupt of acc mon
During pre--flight test, a failure of the autotrim monitor did not disable the
accelerometer monitor for > 5 seconds. This preflight test step fails the
autotrim and the acceleration monitors. At 3 seconds and at 5 seconds, from
the start of the failure of the autotrim and acceleration monitors, the software
verifies that the acceleration monitor fail output has not failed. The software
verifies at 11 seconds that the acceleration monitor fail output has failed.
Pitch Axis operation is disallowed.
