Figure 1-12 AHRS Operation
Loss of GPS, magnetometer, or air data inputs is communicated to the pilot by
message advisory alerts (refer to Section 6 for specific AHRS alert information).
Any failure of the internal AHRS inertial sensors results in loss of attitude and
heading information (indicated by red “X” flags over the corresponding flight
instruments).
A maximum of two GPS inputs are provided to the AHRS. If GPS information
from one of the inputs fails, the AHRS uses the remaining GPS input and an
alert message is issued to inform the pilot. If both GPS inputs fail, the AHRS
will continue to provide attitude and heading information to the PFD as long as
magnetometer and airspeed data are available and valid.
If the magnetometer input fails, the AHRS continues to output valid attitude
information and GPS Track information is used; however, the heading display
on the PFD is flagged as invalid with a red “X,” “TRK” in magenta is annunciated
to the right of the Track value, and the Track value color is changed from white
to magenta.
