  • Page 10: Description And Operation

    EGPWS LINE MAINTENANCE MANUAL DESCRIPTION AND OPERATION 2.1 GENERAL SYSTEM DESCRIPTION The purpose for the Enhanced Ground Proximity Warning System (EGPWS) is to help prevent accidents caused by Controlled Flight Into Terrain (CFIT), obstacles, or severe windshear. The Enhanced Ground Proximity Warning Computer (EGPWC) accepts a variety of aircraft sensors and system inputs and applies alerting algorithms to provide the flight crew with aural messages and visual annunciations when the boundaries of alerting envelopes are exceeded.
  • Page 11: Enhanced Ground Proximity Warning Computer (Egpwc)

    Proximity Warning Computer (EGPWC). The MK V and MK VII EGPWC are digitally controlled computers housed in a 2 MCU ARINC 600-6 form factor chassis intended for Air Transport type aircraft. Installation configuration is defined by program pin strapping in the aircraft.
  • Page 12: Mode 5 - Descent Below Glideslope

    EGPWS LINE MAINTENANCE MANUAL 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.

  • Page 14: Mode 7 - Windshear Detection (Optional For Mk V/Vii Only)

    The TCF function is enhanced in all fixed-wing models (beginning with release –210-210 for the MK V/VII) with the addition of a Runway Field Clearance Floor (RFCF) alerting function. RFCF is based on current aircraft location, destination runway center point position, and Geometric Altitude or altitude Above Sea Level (ASL) relative to the destination runway.
  • Page 15: Terrain Alerting And Display (Optional)

    The EGPWS Runway Database consists of data records for all airport runways offered for the coverage provided by the Terrain Database. For the MK V and MK VII, all hard surface runways in the world 3500 feet or greater in length are supported.
