SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS AUDIO & CNS FLIGHT MANAGEMENT AVOIDANCE Appendix A System Annunciation Comment Attitude and Heading Reference System is aligning. Display system is not receiving attitude information from the AHRS. AHRS calibration incomplete or configuration module failure. This annunciation is seen only when the autopilot is engaged. The annunciation indicates an AHRS monitor has detected an abnormal flight parameter, possibly caused by strong turbulence. In this case, the situation should correct itself within a few seconds. If there is an actual failure, a yellow "X" soon appears over the Attitude Indicator. 'GPS LOI' Indicates Loss of Integrity of GPS information. GPS information is either not present or is invalid for navigation use. Note that AHRS uses GPS inputs during normal operation. AHRS operation may be degraded if GPS signals are not present (see AFM). If GPS integrity is subsequently restored, system displays 'GPS INTEG OK' annunciation. Display system is not receiving valid ISA information from air data computer. System Annunciation Comment Display system is not receiving airspeed input from air data computer. Display system is not receiving vertical speed input from the air data computer. Display system is not receiving heading input from the AHRS.
