autotrim not working properly... did ground test with Jason. Elev trim tab only moves in 1 direction when in ALT HOLD mode. Works fine in normal AP mode and trim tab direction is correct
Jason suspected TT pitch servo micro swich. Had another one at hangar so I swapped it out and redid ground test. No joy... exact same test results. Wiring, connection or trim module issue? Jason is thinking on it.
Got a real bad ADSB flight report... looks like GNS 530W GPS position info is not being transmitted properly. checked numerous things in 530 config; Jason called Garmin
