SECTION 4
Operational
Availability
Monitors are operationally available anytime the EGPWS is
powered and the following conditions are met:
• The software for the Monitor functions have been loaded
and enabled into an EGPWS (with software version -230-
230 (or later) and a minimum of Terrain Database version
454 if RAAS or any of the Stabilized Approach Monitors
are enabled, otherwise Terrain Database Version 435 or
later is required);
•
The aircraft is on or approaching an airport in the runway
database; and
• Monitors are functional (e.g.,
available and not faulted, GPS position accuracy meets
minimum requirements, there are no internal EGPWS
faults).
Monitor operational availability is integrated into the existing
EGPWS fault monitoring and self-test functions. Consistent
with approved EGPWS self-test design, the loss of Monitor
functions is indicated on-ground only during an EGPWS self-
test. There is no automatic annunciation of the loss of Monitor
functionality. The audio self-test messages are as follows.
Monitor Self-Test Audio Messages:

Level 1 Self-Test.
“Approach Monitor INOP”

function is inoperative. Annunciated on ground
during Level 1 Self-Test.
