Mark V and Mark VII EGPWS Pilot’s Guide EGPWS Honeywell is constantly striving to improve the EGPWS database in content, resolution, and accuracy. Notification of a Database database update is accomplished by Service Bulletin. Continued Database updates are distributed on PCMCIA data cards and downloaded via a card slot in the front panel of each EGPWC.
Mark V and Mark VII EGPWS Pilot’s Guide BASIC FUNCTIONS: MODE 1 Mode 1 provides alerts for excessive descent rates with respect to altitude AGL and is active for all phases of flight. Excessive This mode has inner and outer alert boundaries as illustrated Descent in the diagram and graph below.
Mark V and Mark VII EGPWS Pilot’s Guide MODE 1 If a valid ILS Glideslope front course is received and the aircraft is above the glideslope centerline, the outer (sinkrate) Continued boundary is adjusted to desensitize the sinkrate alerting. This is to prevent unwanted alerts when the aircraft is safely Glideslope capturing the glideslope (or repositioning to the centerline)
Mark V and Mark VII EGPWS Pilot’s Guide MODE 2A Mode 2A is active during climbout, cruise, and initial approach (flaps not in the landing configuration and the aircraft not on glideslope centerline). If the aircraft penetrates the Mode 2A caution envelope, the aural message “TERRAIN, TERRAIN”...
Mark V and Mark VII EGPWS Pilot’s Guide MODE 2A The graph below shows how the upper boundary of the Mode 2 alert envelope varies as a function of the aircraft speed. As Continued airspeed increases from 220 knots to 310 knots, the boundary expands to provide increased alert times at higher airspeeds.
Mark V and Mark VII EGPWS Pilot’s Guide MODE 2B Mode 2B provides a desensitized alerting envelope to permit normal landing approach maneuvers close to terrain without unwanted alerts. Mode 2B is automatically selected with flaps in the landing configuration (landing flaps or flap over-ride selected) or when making an ILS approach with Glideslope and Localizer deviation less than 2 dots.
Mark V and Mark VII EGPWS Pilot’s Guide MODE 2B During an approach, if the aircraft penetrates the Mode 2B envelope with either the gear or flaps not in the landing Continued configuration, the aural message “TERRAIN, TERRAIN” is generated and the EGPWS caution lights illuminate. If the aircraft continues to penetrate the envelope, the EGPWS warning lights illuminate and the aural message “PULL UP”...
Mark V and Mark VII EGPWS Pilot’s Guide MODE 3 The aural message is enunciated twice for each 20% degradation in altitude. Upon establishing a positive rate of Continued climb, the EGPWS caution lights extinguish and the aural alert will cease. If the Aural Declutter feature is disabled, the warning is enunciated continuously until positive climb is established.
Mark V and Mark VII EGPWS Pilot’s Guide MODE 4A Below 1000 feet AGL and above 190 knots airspeed, the Mode 4A aural alert is “TOO LOW TERRAIN”. This alert Continued is dependent on aircraft speed such that the alert threshold is ramped between 500 feet at 190 knots to 1000 feet at 250 knots.
Mark V and Mark VII EGPWS Pilot’s Guide MODE 4B Below 245 feet AGL and less than 159 knots (185 knots for Boeing 747-8) airspeed, the Mode 4B aural alert is “TOO Continued LOW FLAPS”. For turboprop and selected turbofan aircraft, the “TOO LOW FLAPS”...
Mark V and Mark VII EGPWS Pilot’s Guide MODE 4C Mode 4C is based on an EGPWS computed Minimum Terrain Clearance (MTC) floor that increases with Radio Altitude. It Continued is active after takeoff when the gear or flaps are not in the landing configuration.
Mark V and Mark VII EGPWS Pilot’s Guide MODE 5 Mode 5 provides two levels of alerting for when the aircraft descends below glideslope, resulting in activation of EGPWS Excessive caution lights and aural messages. Deviation The first level alert occurs when below 1000 feet Radio Below Altitude and the aircraft is 1.3 dots or greater below the beam.
Mark V and Mark VII EGPWS Pilot’s Guide MODE 5 • The upper altitude limit for the alert is modulated with vertical speed. For descent rates above 500 FPM, the upper Continued limit is set to the normal 1000 feet AGL. For descent rates lower than 500 FPM, the upper limit is desensitized (reduced) to a minimum of 500 feet AGL.
