1.5 Description o f Equipment
The MK VI/MK VIII EGPWS is a rack mount ground proximity warning (GPWS) and terrain awareness and
warning (Class A TAWS) computer. Some of the system features include:
♦ Basic Ground Proximity Warning Modes 1-5
♦ Mode 6 Altitude Callouts and Bank Angle alert
♦ Terrain Clearance Floor
♦ Terrain and Obstacle Awareness alert and display
♦ Terrain map with runways >= 2000 feet in length (optionally >= 3500 feet in length on the MK VIII EGPWS)
♦ Internal GPS card (MK VI 965-1190-0XX and MK VIII 965-1220-0XX only)
♦ Front loading updateable database (requires Smart cable)
♦ External Configuration Module (with a Real Time Clock for use with Internal GPS)
♦ Internal heater blanket for operation outside of the heated area of the aircraft
♦ Fixed Gear operation
1.5.1 MK VI EGPWS Computer
The MK VI EGPWS computer is available under P/N 965-1180-0XX without internal GPS and P/N 965-1190-
0XX with internal GPS. The MK VI EGPWS computer is intended for small turboprop aircraft that provide a
mixture of analog and digital interfaces. The type of supported displays is limited and does not typically include
EFIS displays (Collins ProLine II and Bendix EFIS 40/50 are supported). The terrain database included with the
MK VI EGPWS computer is regional having three separately defined databases for the AMERICAS (North &
South America), ATLANTIC (Europe/Asia/Africa), and PACIFIC (Asia/Australia).
1.5.2 MK VIII EGPWS Computer
The MK VIII EGPWS computer is available under P/N 965-1210-0XX without internal GPS and P/N 965-1220-
0XX with internal GPS. The MK VIII EGPWS computer is intended for regional turboprop and small turbofan
aircraft that provide a mixture of analog and digital interfaces. The type of supported displays is limited and
includes some EFIS displays. The terrain database included with the MK VIII EGPWS computer is global.
1.5.3 MK VI/MK VII I EGPWS Configuration Module
The MK VI/MK VIII EGPWS Configuration Module is available under P/N 700-1710-020. The MK VI/MK VIII
EGPWS use a Configuration Module installed in the aircraft wiring to store aircraft/EGPWS interface
configuration and includes a Real Time Clock for EGPWS installations using internal GPS. The Configuration
Module is read by the EGPWS only during power up. The configuration is copied into Non Volatile Memory
(NVM) of the EGPWS. The Configuration Module is programmable via an RS-232 interface with the EGPWS.
The contents of the Configuration Module can also be read back via the same RS-232 interface. An optional
Configuration Module is available under P/N 700-1710-001 for non-Internal GPS operation only.
The 700-1710-020 Configuration Module includes a GPS Real Time Clock (RTC) counter and position memory
to aid in GPS initialization. A capacitor will keep the position memory retained and clock current for
