Loss Of Valid Egpws Data; No Data Received - Honeywell Bendix/King KMD 550 Pilot's Manual Addendum

LOSS OF VALID EGPWS DATA

If another page of the KMD 550/850 is being viewed and the EGPWS
data becomes invalid the following message will be displayed.
This may indicate that the EGPWS no longer has a valid GPS position. It
could also indicate a problem with the EGPWS unit or the installation
wiring. Note that the Terrain Icon is displayed with a red circle and slash
through it to indicate that the EGPWS is no longer functioning properly.

NO DATA RECEIVED

If the KMD 550/850 is not receiving any data from the EGPWS sensor
then the following screen will be displayed. This could indicate that
power is not being provided to the EGPWS (e.g. a pulled breaker), a bad
wiring connection between the display and the EGPWS sensor, or a
failed EGPWS unit.
