3. EGPWS System Test
A. General
(1) The system test does an internal EGPWS check and a check of system interfaces.
(2) This test uses GPS data. The airplane must be moved to a position where the GPS
antennas have a clear view of the GPS satellites.
(3) Various systems interface with the EGPWS. Some systems send data. Some systems
send a single discrete signal.
(4) The systems that send data have verbal error messages. In this procedure, you do a
check of these signals when you turn a system off and hear an aural message
annunciated.
(a) Some systems supply two sources and are redundant. You turn one system off and
hear an aural message. The EGPWS will still function with data from the redundant
system. Then, you turn the second system off and look for the INOP light on the
ground proximity warning module to come on.
