Comments
The #1 AHRS is using the backup GPS path.
Primary GPS path has failed. The system should
be serviced when possible.

mode. The system should be serviced.
The #1 AHRS earth magnetic field model is out
of date. Update magnetic field model when
practical.
The #1 AHRS is not receiving true airspeed from
the air data computer. The AHRS relies on GPS
information to augment the lack of airspeed.
The system should be serviced.
The #1 AHRS and #2 AHRS magnetic model
database versions do not match.
SBAS not available. The system is calculating
the VNAV profile using BARO VNAV.
Use LNAV minima when approach is
downgraded or may use LNAV/VNAV minima
with Baro-VNAV.
The system notifies the pilot the loaded
approach is not active. Activate approach when
required.
Special use airspace is ahead of aircraft. The
aircraft will penetrate the airspace within 10
minutes.
