EGPWS LINE MAINTENANCE MANUAL

3.8.4 GND LANDING FLAP DISCRETE OR FLAP OVERRIDE

Type:

Supplied by Flap or Flap selector handle switch. This input can be paralleled with, or used

 

exclusively by a Flap Override Switch if an alternate source of Flap Position is used.

Signal Status: Landing Flaps or Not Landing Flaps

Fault monitoring: Indication of landing flaps selected for more than 60 seconds at airspeeds above 250 knots will result in a flap switch fault which will cause a GPWS INOP indication.

Note: This can be caused either by a flap switch fault or by the Flap Override switch being left in the on position.

Level 6 Audio readout

3.8.5 +28V LANDING FLAP OR FLAP OVERRIDE DISCRETE

Type:

Supplied by Flap or Flap selector handle switch. This input can be paralleled with, or used

 

exclusively by a Flap Override Switch if an alternate source of Flap Position is used.

Signal Status:

Landing Flaps or Not Landing Flaps

Fault monitoring: Indication of landing flaps selected for more than 60 seconds at airspeeds above 250 knots will result in a flap switch fault which will cause a GPWS INOP indication.

Note: This can be caused either by a flap switch fault or by the Flap Override switch being left in the on position.
