A. General
(1) Warning modes The serial digital data and discrete data inputs are interfaced and used in different combinations to monitor aircraft situation awareness with respect to the terrain. The following functions are implemented within the Enhanced GPWS: Mode 1 - Excessive rate of descent Mode 2 - Excessive closure rate with terrain Mode 3 - Descent after takeoff and minimum terrain clearance Mode 4 - Unsafe terrain clearance Mode 5 - Descent below glide slope Terrain Awareness and Display (TAD) Terrain Clearance Floor (TCF)

(2) Aural alert messages Each mode computes and compares aircraft behaviour with a corresponding alert envelope. If the alert envelope is penetrated, visual and aural alerts are generated. The aural message is broadcast through the cockpit loud speakers. The messages are as follows:
MODE AURAL ALERTS VISUAL ALERTS
1 SINK RATE GPWS
1 PULL UP GPWS
2 TERRAIN GPWS
2 TERRAIN TERRAIN GPWS
2 PULL UP GPWS

4 TOO LOW GEAR GPWS
4 TOO LOW FLAPS GPWS
5 GLIDE SLOPE G/S

TCF TOO LOW TERRAIN GPWS
Each of these alerts inhibits the automatic call out.
