EGPWS LINE MAINTENANCE MANUAL 2 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 b

EGPWS LINE MAINTENANCE MANUAL 2.1.1 ENHANCED GROUND PROXIMITY WARNING COMPUTER (EGPWC) All EGPWS functions are processed by a single Line Replaceable Unit (LRU) called the Enhanced Ground 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. The MK VI and MK VIII EGPWC are d

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. Two levels of alerting are provided. If the aircraft is below 1000 feet AGL and gets to or exceeds

EGPWS LINE MAINTENANCE MANUAL 2.2.6.1 EXCESSIVE BANK ANGLE CALLOUT The Bank Angle Callout feature provides callout enunciation for excessive bank angles based on altitude and bank angle limits defined by aircraft type. It is intended to enhance situational awareness during intentional or unintentional maneuvering, and for protection against wing or engine strikes when close to the runway. When the bank angle limit is reached, the aural callout “BANK ANGLE, BANK ANGLE” is given. Follow-o

EGPWS LINE MAINTENANCE MANUAL When an aircraft penetrates either the TCF or the RFCF alert envelope, the aural message “TOO LOW TERRAIN” will occur. This aural message will occur once when initial envelope penetration occurs, and one time thereafter for each 20% degradation in either Altitude (AGL) or Altitude (ASL) depending on which envelope was violated (TCF or RFCF respectively). EGPWS cockpit alert annunciations remain illuminated until the alert envelope is exited. The TCF and RFCF

EGPWS LINE MAINTENANCE MANUAL The Obstacle Database (in MK V and MK VII -204-204 and later, and MK VI, MK VIII and MK XXII) is a separate file included within the terrain database. Both files are loaded into the EGPWS in the terrain database PCMCIA card. The obstacle database is accessed by the EGPWC application software only if obstacle alerting is enabled by installation configuration. The obstacle data is processed by the EGPWS in the same fashion as terrain, and is presented on the d

EGPWS LINE MAINTENANCE MANUAL installation does require that the EGPWS has a source of GPS data, software -230-230 or later, Terrain Database version 454 or later, and the Reloadable Customer Definitions (RCD) is loaded. When enabled, Altimeter Monitor operates automatically, without any action required from the flight crew. Altimeter Monitor availability can be verified by performing an EGPWS self test.

EGPWS LINE MAINTENANCE MANUAL 2.3 SYSTEM MAINTENANCE 2.3.1 MAINTENANCE PHILOSOPHY The EGPWS is an “on-condition” only maintenance system. No scheduled maintenance is required. This is accomplished by both continuous Built-In-Test (BIT) and event initiated test functions. Event initiated test refers to both power-up tests and manually activated Self-Tests. Results of these functions are indicated by system status indicators and messages so that the systems functionality can be assessed
