Cross Check Attitude
Presented when the EBD AHRS internal integrity monitor determines that attitude is potentially
degraded. When a CROSS CHECK ATTITUDE annunciation is presented, the pilot should cross check
attitude, airspeed, and altitude indications with other sources of primary ight information.
Figure 6-16
Check Pitot Heat
The CHECK PITOT HEAT annunciation accompanies the ATTITUDE FAIL annunciation and is
presented when the software detects an obstruction in the pitot system that could potentially
degrade the attitude solution. This annunciation is removed when the detected condition is
resolved, which would be followed by an automatic AHRS reset. A GPS is required for this monitor
to be enabled.
