Flight History Retrieval Process | Honeywell EGPWS guide

Flight History Retrieval Process

•Flight History information is stored in the EGPWS in a specific area of the non-volatile memory

•Data can be downloaded via PCMCIA or CF card

-Card must be programmed with special instruction file

-Process similar to terrain database upload, requires < 5 minutes

-Cards available upon request from Honeywell Engineering

-Data is encrypted

•Decoding of encrypted information is done by Honeywell ell

using proprietary tools, tools are not distributed

•If unit is damaged:

-Circuit boards can be placed in donor units or fixtures

-Memory chips can be removed and data retrieved via chip reader

Honeywell can accept data directly from chip reader

Occasionally memory chips are damaged and unreadable
