1.1 Part Number
This document is the Product Specification for the Enhanced Ground Proximity Warning System (EGPWS), Honeywell part
numbers:
965-1176-xxx: MKVI EGPWC
965-1186-xxx: MKVI EGPWC with Internal GPS
965-1206-xxx: MKVIII EGPWC
965-1216-xxx: MKVIII EGPWC with Internal GPS
Differences, where they exist, between the different part numbers, are highlighted within this document.
The 965-1176-xxx series part number MKVI EGPWCs are intended for turboprop aircraft that provide a mixture of limited
analog and digital interfaces. Display support includes several weather radar indicators and limited EFIS support. The terrain
database included with the EGPWC is regional. See Figures 1.3.2-2, -3 and -4 for regions.
The 965-1186-xxx series part number MKVI EGPWCs include an internal GPS-PXPRESS card and are otherwise as 965-
1176-xxx.
The 965-1206-xxx series part number MKVIII EGPWCs are intended for regional turboprop and turbofan aircraft that
provide a mixture of limited analog and digital signal interfaces. Display support includes several weather radar indicators
and limited EFIS support. The terrain database included with the EGPWC is global.
The 965-1216-xxx series part number MKVIII EGPWCs include an internal GPS-PXPRESS card and are otherwise as 965-
1206-xxx.
In order to minimize complexity, the EGPWC utilizes a 10 digit part number. This 10 digit part number will identify the
configuration of the EGPWC, which affects form, fit, or function as seen by the pilot. This part number is defined as follows:
• 965-1ABC-DDD (example 965-1176-001)
• A = 1 (EMVI) or 2 (EMVIII)
• B = 7 (EMVI without internal GPS) or 8 (EMVI with internal GPS) or 0 (EMVIII without internal GPS) or 1 (EMVIII
with internal GPS
• C = MK VI or MK VIII EGPWC Hardware (including boot code). C = 6, 7, 8, 9 as hardware part numbers roll.
• DDD = Application software (including configuration software)
• Terrain Database(including the Envelope Modulation Database)- Version not identified in 10-digit part number but with
a separate identifier.
• Modifications - All modifications will be identified via “mod dots”. No mod dots will be skipped.
The digits identifying the application software will match the respective version number of the application software.
See section 6.10.11 for details on configuration management.
