in the computation of attitude
information; Attitude may be
degraded.
HDG SOURCE FAIL
The Remote Magnetometer has
failed or is no longer communicating
via SkyView HDX network.
CPU TEMP CRITICAL
The SkyView HDX Display internal
temperature is too high. The display
may shut down at any time to
prevent permanent damage unless
immediate action is taken to cool it
down.
CROSS CHECK ATTITUDE
While in flight, IAS has become
invalid (likely due to icing or
obstruction), and all GPS sources
have failed. The attitude indication
should be considered unreliable.

Compass needs calibration
NO ADSB OUT: GPS LOST
The GPS source that provides GPS
position to the Transponder for
ADS-B Out transmission is offline.
