6.10.13.3 Ground History Output Format
Ground history is described in section 6.10.3.4.
When requested, the EGPWS will output ground history information in the following order and format:
“GROUND HISTORY:”

“GPWS COMPUTER FAULTS:” (if any exist),
Internal Fault 1
Internal Fault 2 (etc.)
“GPWS EXTERNAL FAULTS:” (if any exist),
External Fault 1

If no Ground history events exist, the EGPWS will output “NO EVENTS” on the line immediately following “GROUND

The Ground history event text will be one of the following identifiers: “GPW INOP”, “Mode 6 INOP”, “Bank Angle INOP”,
“TA&D INOP”, “Envelope Modulation INOP”, “Present Status”, or “Self-Test, Level 1”.

<Alert Event 1> < Operating Time >
<Alert Event 2> < Operating Time >
etc.
“FLIGHT LEG” <the next most recent leg number with a warning>
<Alert Event 1> < Operating Time >
etc.
NOTE: For a specific flight leg, <Alert Event 1> and <Alert Event 2> may be the same type of alert if that type of alert
