When the GDU 620 attitude monitors have detected an AHRS malfunction, or
the inability to actively monitor the AHRS, a “Check Attitude” annunciation will
be displayed on the PFD and the autopilot will automatically disconnect.
NOTE: If an optional GAD 43 Adapter is installed and there is an AHRS
malfunction, the “Check Attitude” annunciation will appear on the
PFD. If it appears the autopilot will disengage and the pilot should
IMMEDIATELY control the aircraft by reference to the standby attitude
indicator.
