- Radio Altimeter.
Does GPWS ‘look ahead’?
No
Operating range of GPWS in feet?
Ground to 2500ft
What does TAWS stand for>
Terrain Awareness Warning System
What is the mnemonic for the different modes of GPWS?
Send - Sink Rate
The - Terrain closure
Drunk - Dont’ Sink
To - Terrain (Gear, Flaps, Terrain)
Go - Glide Slop
Buy - Bank angle, Call outs
Wine - Windshear
The GPWS provides…
visual and audible warning signals to a pilot when the aircraft’s proximity to the terrain poses a potential threat to its safety.
Mode 1: is ?, what is the alert ?, what is the warning ? Does it use baro or rad alt?

Warning: Whoop Whoop Pull Up
Baro altitude
Mode 2A: is ?, what is the alert ?, what is the warning ? What about the configuration?
Excessive Terrain Closure Rate
Flaps not in landing configuration
Alert: Terrain Terrain
Warning: Whoop Whoop Pull Up
