Single GPS Failure Conditions:
1. Place a shroud over the GPS antenna for GIA1
to prevent signal reception. Verify loss of signal
on MFD AUX page 3.
2. Check for desired results.
3. Remove shroud from the GIA1 GPS antenna
and allow GPS 1 to reacquire satellites.
4. Place a shroud over the GPS antenna for GIA2
to prevent signal reception. Verify loss of signal
on MFD AUX page 3.
5. Check for desired results.
6. Remove shroud from the GIA2 GPS antenna
and allow GPS 2 to reacquire satellites.
GPS Failure – For each of the specified GPS failure
conditions, the following shall remain valid on the
PFD throughout the procedure:
9 Attitude and Heading from AHRS.
9 Airspeed, Altitude, Vertical Speed, and OAT from Air

(SW v0321.19 or earlier)
Dual GPS Failure Conditions:
1. Cover both GPS antennas. Verify loss of
signal on MFD AUX page 3.
2. Check for desired results.
3. Remove shrouds from GPS antennas.
4. Allow both receivers to re-acquire satellite
signals before continuing.
Dual GPS Failure – For a dual GPS failure, the following
shall occur:
9 GPS CDI is removed.

verify the TAWS AVAILABLE aural alert is given.
Verify that the system returns to normal navigation mode
(GPS CDI restored, DR annunciation removed, & GPS
