Product Specification
HIF-2121/R5 CAGE CODE: 97896 SCALE: NONE SIZE: A DWG NO: 965-1176-601 REV: D SHEET 133
In addition, the EGPWC ATP performs a “final” check to ensure that the internal CCAs and software are correct for the
indicated EGPWC part number.
6.10.11.4 Production Configuration Management
The application software, Envelope Modulation database and terrain database will be loaded into the EGPWC at the 965
production level. The loading will be done via PCMCIA card(s). The PCMCIA card(s) will contain the upload list and
appropriate “canner” output. These files will be listed in the appropriate VDD and/or drawing which describes the
programming of the PCMCIA card(s).
Boot code must be present prior to PCMCIA loads. If boot code resides in the EGPWC it can be updated with a PCMCIA
load of boot software.
The other software loaded at the 965 production level can be loaded via separate PCMCIA cards or via one PCMCIA card.
For future software updates (i.e. new configuration software) a separate PCMCIA card may be required so that just the new
software (i.e. configuration software) can be loaded into fielded units. However, for production it will be most desirable to
have all of the other software components loaded via one PCMCIA card.
6.10.12 Present Status Output Format
Present status information includes software and database versions, a listing of internal and external faults (if they exist),
configuration item options selected. When requested this data will be output to the user. The present status is output once
and then not updated, unless another request for present status is submitted.
EGPWS present status information is output in a manner that is consistent with the self-test output and the output of EGPWS
Flight history information. Refer to section 6.10.2.2 for a description of possible faults.
When requested, the EGPWS will output present status information in the following order (each item is described in detail in
the following subsections) and format:
1) Software & Database Version Numbers
2) Current Faults,
a) Internal Faults (if any exist),
i) Internal Fault 1
ii) Internal Fault 2 (etc.)
b) External Faults (if any exist),
i) External Fault 1
ii) External Fault 2 (etc.)
3) System Configuration
a) Selected Options (A/C Type, Voice Menu, Callout Menu, etc)
b) Other options selected (deviations from the default configuration).
