EGPWS LINE MAINTENANCE MANUAL MK V & MK VII EGPWC (left) and MK VI, MK VIII, MK XXII EGPWC (right) Figure 1-1 - Enhanced Ground Proximity Warning Computers 1.3 REFERENCE DOCUMENTS The following documents are identified as additional EGPWS references: MK V and MK VII: 965-0976-603 ..Product Specification for the EGPWS (MK V and MK VII)
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.
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.
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.
EGPWS LINE MAINTENANCE MANUAL MODEL CALLOUT DESCRIPTION VIII XXII 500 TONE Provides 2 second 960 Hz tone at descent below 500 • • feet SMART “FIVE HUNDRED” At descent below 500 feet (only) during non-precision • • • • • approach “FIVE HUNDRED”...
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.
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.
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.
2.2.17 ALTIMETER MONITOR (OPTION FOR MK V AND MK VII ONLY) The Altimeter Monitor function offers significant safety enhancements for aircraft equipped with Honeywell’s MK V or MK VII Enhanced Ground Proximity Warning Systems (EGPWS). Honeywell’s Altimeter Monitor is a software enhancement hosted in the EGPWS Unit.
Configuration Monitor is a software enhancement hosted in the EGPWS Unit. Takeoff Flap Configuration Monitor uses GPS position data, Flap angle inputs, and the Honeywell EGPWS Database to provide aural alerts that supplement flight crew awareness of improper flap setting when the aircraft is aligned on a runway prior to takeoff.
EGPWS LINE MAINTENANCE MANUAL 2.2.21 LAMP FORMAT The EGPWS contains two different caution/warning lamp illumination formats as described below. Lamp Format 1 provides EGPWS warning (red) and caution (amber) alert lamp drive logic such that: • Only a Mode 5 “Glideslope” alert will activate the caution lamp output (amber). •...
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.
220.127.116.11 FRONT PANEL PCMCIA INTERFACE For the MK V and MK VII, a PCMCIA card slot is provided in the front panel. For the MK VI, MK VIII, and MK XXII the PCMCIA interface utilizes an external PCMCIA interface called a “SmartCable” connected to the front panel Test Connector.
Self-Test aural is heard over the cockpit speaker, cockpit interphone system, or through the headphone jack on the EGPWC front panel (MK V and MK VII only). Details of these Self-Test levels are provided in Fault Isolation Section 3.
EGPWS LINE MAINTENANCE MANUAL FAULT ISOLATION (TROUBLESHOOTING) 3.1 GENERAL The troubleshooting methods provided in this section identify system and sensor or subsystem faults to the lowest level possible. Additional fault isolation in the installation or associated sensors or subsystem should be performed using the aircraft installation and wiring diagrams and other supporting documentation in accordance with established maintenance procedures.
Action: removing or replacing the EGPWC for repair (see Removal/Installation section) Enunciation: “AIRCRAFT CONFIGURATION DATA BASE CRC FAILED” (MK V or MK VII only) Probable Cause: EGPWC internal configuration database error. Pull power to the EGPWS for one minute and cycle power to clear all potential faults before...
EGPWS LINE MAINTENANCE MANUAL POSSIBLE SELF-TEST PREAMBLE RESULTS Enunciation: “CONFIGURATION MODULE NOT PROGRAMMED” (MK VI, MK VIII, MK XXII only) Probable Cause: The Configuration Module is not programmed. Action: Program the Configuration Module. See Maintenance Practices section. Enunciation: “CONFIGURATION MODULE NOT COMPATIBLE” (MK VI, MK VIII, MK XXII only) Probable Cause: The Configuration Module is not compatible with the EGPWC h/w or s/w or it’s faulty.

EGPWS LINE MAINTENANCE MANUAL TABLE 3-4: LEVEL 2 SELF-TEST - EXTERNAL FAULTS THE FOLLOWING EXTERNAL FAULTS ARE AVAILABLE IN LEVEL 2 SELF-TEST: Enunciation: “<BUS> Inactive” Example: GPS BUS 1 Inactive Input source not powered or a wiring problem exists between source LRU and the Probable Cause: EGPWC.
EGPWS LINE MAINTENANCE MANUAL THE FOLLOWING EXTERNAL FAULTS ARE AVAILABLE IN LEVEL 2 SELF-TEST: Description: SELF-TEST INVALID (WinVIEWS ONLY) Probable Cause: Electrical short at the Self-Test input. Action: Verify wiring from the Self-Test discrete. Enunciation: “MOMENTARY TERRAIN SELECT 1 (or 2) INVALID” Probable Cause: Electrical short at the Terrain Select inputs.
EGPWS LINE MAINTENANCE MANUAL TABLE 3-5: GENERAL FAILURE CODE IDENTIFIERS For example, if the Computed Airspeed from Air Data Computer #1 is failed (i.e., SSM = Fail Warning), the following messages would be enunciated: “CURRENT FAULTS” “EGPWC OK” “EXTERNAL FAULTS” “AIR DATA BUS 1 COMPUTED AIRSPEED FAULT”...
(see Maintenance Practices) or replaced (see Removal/Installation section). If the unit is a MK V or MK VII with integral GNSSU (-060 part number), and external faults are indicated on GPS signals (e.g., GPS BUS 1 LATITUDE FAULT), an internal fault may exist. In this case both fault lights will be on and the message INTERNAL GPS FAULT will also be indicated.

4.2.2 LOADING A DATABASE A database is loaded into the EGPWC via the PCMCIA card slot in the front panel in the MK V and MK VII. In the MK VI, MK VIII, and MK XXII a “Smart Cable” data-loader is connected to the Test connector on the front panel.
For the MK V or MK VII, ensure the notch on the bottom of the PCMCIA Card is in the down position. Push the card in carefully until the PUSH TO EJECT button on the front Panel is fully extended. This will be when the face of the button is nearly level with the rear of the inserted PCMCIA Card.
9. Remove the PCMCIA Card, For the MK V or MK VII, depress the PUSH TO EJECT button on the EGPWC front panel. For the MK VI or MK VIII, and MK XXII, carefully grasp the card and pull from the Smart Cable.
EGPWS LINE MAINTENANCE MANUAL 4.4 PROGRAMMING THE CONFIGURATION MODULE (MK VI, MK VIII, MK XXII ONLY) Programming the EGPWS Configuration Module is accomplished using WinVIEWS on a PC connected to the EGPWC via the RS-232 interface. Prior to this activity, the necessary and desired configuration should be determined based on the MK VI, MK VIII, or MK XXII Installation Design Guide referenced in Section 1.3.
EGPWS LINE MAINTENANCE MANUAL 4.4.1 CONFIGURATION MODULE REPROGRAMMING (MK VI, MK VIII, MK XXII ONLY) Reprogramming the EGPWS Configuration Module is accomplished similar to the programming process above.
