EGPWS

Brand: Honeywell Bendix/King

The Mark V EGPWS, exceeding the FAA TSO - C151b requirements for TAWS, provides protection against Controlled Flight Into Terrain (CFIT) and windshear. The system achieves this objective by accepting a variety of aircraft parameters as inputs, applying proprietary alerting algorithms, and providing the flight crew with aural alert messages, visual annunciations, and displays in the event that the boundaries of any alerting envelope are exceeded.

EGPWS incorporates many features not found in some competing systems such as pin-selectable altitude callouts, envelope modulation, geometric altitude algorithm, turn extrapolation, auto display pop-up, auto tilt of weather radar, and the ability to host Honeywell's Runway Awareness and Advisory System.

Features

• World wide terrain, obstacle and airport database
• Man-made obstacles database - offers protection against radio and TV towers, tethered balloons, etc.
• Optional internal GPS card
• Geometric altitude computations - overcomes barometric altimetry limitations, operations in QFE areas or areas requiring compensation for cold weather.
• “Peaks” display - provides display of the highest and lowest elevation terrain within the display range
• Runway clearance floor - provides protection against inadvertent landings below airport runway thresholds
• Vertical situation display - provides altitude awareness in relation to the terrain as well as an aircraft trend vector
• Radar autotilt - allows the EGPWS to provide terrain elevation data to compatible radars for controlling the tilt of the radar antenna during its scan
• Envelope modulation - provides terrain “fine tuning” at airports with difficult approaches around significant terrain to increase safety and decrease potential nuisance alerts
