Note that during normal operations, the crew would only be
exposed to the five routine advisories for the entire period
between push-back at the departure airport and taxi-in at the
destination airport. The five advisories alone have the
potential to address many classic runway incursion scenarios.
RAAS annunciations are heard over the same aircraft audio
systems that presently provide EGPWS audio caution and
warning alerts in the flight deck. The volume of RAAS
messages is controlled by the EGPWS and the RAAS
message volume level is based on the expected flight
operation for each message.
As mentioned above, RAAS operates automatically, without
any action required from the flight crew. The EGPWS circuit-
breaker disables all EGPWS functionality including RAAS.
The EGPWS Self-Test push-button (if available) allows the
crew to verify the operational availability of all EGPWS
