provides “TOO LOW TERRAIN” or “TOO LOW FLAPS” depending on airspeed. Mode 4C provides “TOO LOW TERRAIN”. EGPWS alert lights are illuminated during these alerts.

2.2.5 MODE 5 - DESCENT BELOW GLIDESLOPE

Mode 5 provides audio and visual alerts for excessive glideslope deviation when the aircraft descends below the glideslope beam on front-course ILS approaches. Two levels of alerting are provided. If the aircraft is below 1000 feet AGL and gets to or exceeds 1.3 dots glideslope deviation (fly-up), a ‘soft’ (reduced volume) “GLIDESLOPE” is enunciated. Exceeding 2 dots below 300 feet AGL provides a hard (full volume) “GLIDESLOPE” enunciation. EGPWS alert lights are illuminated during these alerts.

2.2.6 MODE 6 - ADVISORY CALLOUTS (OPTIONAL)

The EGPWC can be programmed to enunciate Mode 6 Advisory Callouts based on menu selectable options. Mode 6 includes Altitude Awareness, Minimums/Approaching Minimums, and Bank Angle type callouts as defined for each EGPWS model (refer to an applicable Interface Control Document or Installation Design Guide). The menu selected Advisory Callouts are defined and enabled in the installation configuration. If Altitude Callouts are not enabled, only (DH based) “MINIMUMS” callouts will be provided. The MK XXII offers a tail strike advisory for helicopters.

Only aural callouts are provided for Mode 6. EGPWS alert lights are NOT illuminated for Mode 6 callouts. The following table identifies all of the Mode 6 Callouts that are available and the applicability to each model.
