APPENDIX E - Interface Description Document
1 INTRODUCTION
1.1 Part
Number
This document is the Interface Description Document for the MK VI and MK VIII Enhanced Ground Proximity Warning
System (EGPWS). The EGPWS computer (EGPWC) for these systems are identified by Honeywell part numbers:
965-1180-0XX
MK VI EGPWC With upgraded CPU
965-1190-0XX MK VI EGPWC With upgraded CPU and internal GPS
965-1210-0XX: MK VIII EGPWC With upgraded CPU
965-1220-0XX: MK VIII EGPWC With upgraded CPU and internal GPS
Differences, where they exist, between the different part numbers, are highlighted within this document.
The EGPWC 10 digit part number will identify the configuration of the EGPWC as follows:
965-1ABC-DDD (example 965-1180-020)
A = 1 (MK VI) or 2 (MK VIII)
B = Functionality of hardware (with or without internal GPS or Upgraded CPU). Refer to part number list above for
details.
C = MK VI or MK VIII EGPWC hardware (including boot code). C = 0 as hardware part numbers roll.
DDD = Application Software (including Configuration Software)
The Terrain Database (including the Envelope Modulation Database) Version is not identified in the 10-digit part number
but with a separate identifier on the nameplate.
All modification changes not affecting form, fit or function will be identified via “mod dots”.
The digits identifying the Application software will match the respective version number of the Application software.
1.2 Purpose
