Index
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 output
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.
NOTE: In this case the magnetic standby compass and GPS ground track
can be used to keep the aircraft on the desired heading.
Failure of the air data input has no effect on the AHRS output while AHRS is
receiving valid GPS information. Invalid or unavailable airspeed data in addition
to complete GPS failure results in loss of all attitude and heading information.
1.1.13 Secure Data Cards
The G500 System uses Secure Digital (SD) cards to load and store various
types of data. For basic flight operations, SD cards are required for Terrain,
Obstacle, FliteChart, SafeTaxi, and ChartView database storage as well as
Jeppesen aviation and ChartView database updates. The Navigation Database
update card is generally inserted in the upper SD card slot for database updates
and then removed. Other database cards are normally located in the lower SD
card slot.
NOTE: Ensure the GDU 620 is powered off before inserting or removing
an SD card.
NOTE: Refer to A-1 for instructions on updating the aviation database.
