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 red “X”
soon appears over the Attitude
Indicator.
GPS information is either
not present or is invalid for
navigation use. Note that
AHRS utilizes GPS inputs
during normal operation.
AHRS operation may be
degraded if GPS signals are not
present (see AFM).
Display system is not receiving
airspeed input from air data
computer.

between the PFD and MFD can
cause this annunciation.

Indications
A red ‘X’ through any other
display field (such as engine
instrumentation fields)
indicates that the field is not
receiving valid data.
