AIR DATA INPUT FAILURE
Failure of the air data input has no affect on the AHRS output while AHRS is receiving valid GPS information.
A failure of the air data input while the AHRS is operating in Reversionary No-GPS Mode results in invalid
attitude and heading information on the PFD (as indicated by red ‘X’s).
GPS RECEIVER OPERATION
Each Integrated Avionics Unit (IAU) contains a GPS receiver. Internal system checking is performed to
ensure both GPS receivers are providing accurate data to the PFD. When both GPS receivers are providing
accurate data, the GPS receiver producing the better solution is used by the system. Information collected by
the specified receiver (GPS1 for the #1 IAU or GPS2 for the #2 IAU) may be viewed on the AUX – GPS STATUS
Page.
Viewing GPS receiver status information:
1)
Turn the large
FMS
Knob on the MFD to select the Auxiliary (AUX) Page Group (see this section for information
on navigating MFD Page Groups).
2)
Turn the small
FMS
Knob to select the AUX – GPS STATUS Page (third page in the AUX Page Group).
3)
To change the selected GPS receiver:
Press the desired
GPS
Softkey.
Or
:
a)
Press the
MENU
Key.
b)
Turn the
FMS
Knob to highlight the receiver which is not selected and press the
ENT
Key.
GPS sensor annunciations are most often seen after system power-on when one GPS receiver has acquired
satellites before the other or one of the GPS receivers has not yet acquired an SBAS signal. While the aircraft
is on the ground, the SBAS signal may be blocked by obstructions causing one GPS receiver to have difficulty
acquiring a good signal. Also, while airborne, turning the aircraft may result in one of the GPS receivers
temporarily losing the SBAS signal. If no failure message exists, check the AUX – GPS STATUS Page and
compare the information for GPS1 and GPS2. Discrepancies may indicate a problem.
