3.5.2 System Response to Power Interrupts
On application of power to the EGPWC, the computer will perform a power up BIT test to assure proper system performance
prior to initiation of normal operation. The time delays before commencing normal operation will be as defined in the tables
below. The EGPWC system response to power interrupts will be as follows:
Power interrupt duration System Response Maximum Delay to Normal Operation
T < 200 msec. No effect Not applicable
T ≥ 200 msec.
Cold start 20 seconds Max

3.6.1 Packaging
The MKVI and MKVIII EGPWC are packaged in a similar form factor chassis to the MKVI GPWS except with an additional
50 pin front panel interface connector, an additional 15 pin front panel test connector, an additional TNC connector for the
GPS antenna interface and new status LEDs. The outline length and width are the same but the height is 0.2” taller, this
allows the existing mounting interface to be used. The part number appearing on the front panel identification plate for the
MKVI EGPWS (w/o internal GPS) is 965-1176-0xx. For the MK VI with Internal GPS this is 965-1186-0xx which identifies
the hardware part number and application software version. (MKVIII without and with Internal GPS are 965-1206-0xx and
965-1216-0xx respectively). Additionally the installed database is identified on the front panel.
