It is possible to safely continue flight, even if the PFD failure cannot be corrected in flight, by
referencing the remaining instruments. It may, none the less, be prudent to land at the nearest
airfield.
NOTE
Following information is still available when the PFD fails:
Attitude:
Natural horizon
Altitude:
GPS altitude, Transponder altitude, ground visibility
Heading/Track:
Compass, GPS ground track
Airspeed:
GPS ground speed, stall warning
3.13.5 Magnetometer Failure
1.
AHRS
circuit breaker
RESET, if tripped
NOTE
In the event of a magnetometer failure a red X will be displayed over the course display. If the
GDU 620 is receiving a valid GPS ground track signal, the magnetic heading display will be
replaced with the GPS ground track. The GPS ground track is displayed in magenta.
3.13.6 Complete Navigation System Failure
1.
AHRS
circuit breaker
(see 3.1.1)
RESET, if tripped
2. Navigation
Compass, GPS
NOTE
In the event of a complete navigation system failure (magnetometer and GPS ground track) a
red X will be displayed over the course display and the markings on the compass rose
disappear.
