SECTION 5
RAAS advisories 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
advisories is controlled by the EGPWS - the RAAS message
volume level is based on the expected flight operation for
each advisory. RAAS employs three relative audio volume
levels:
Audio Levels
:
Audio Level
High The Taxiway Take-Off Advisory is issued at the
EGPWS caution and warning alert volume level plus
3 dB.
Medium Distance Remaining advisories and cautions are
issued at the same volume level as EGPWS
cautions and warnings.
Low All other in-air and on-ground advisories (excludes
Distance Remaining and Taxiway Takeoff
Advisories) are issued at the same volume level as
the EGPWS cautions and warnings volume level
* other volumes levels selectable by RAAS configuration
