Q. How do I know what units are being used for the
RAAS distance related advisories?
A. This information is provided during the EGPWS self-test
audio message or on the RAAS status message on the
terrain display.
Q. How does RAAS account for temporary runway closures?
A. RAAS does not include knowledge of prevailing
Notice to Airmen (NOTAM) and therefore factors
such as closure of runways is not reflected by
advisories. Crews are assumed to be cognizant of
Information Service (ATIS) data. Similarly, data on
newly constructed runways or changes to length of
existing runways may not necessarily be included in
the RAAS runway database.
Q. Why does RAAS provide an On Taxiway advisory on
some runways?
A. The runway is not yet in the RAAS database, Crews are
always required to use conventional means to ascertain
and confirm position of runways.
Q. Why doesn't RAAS always provide an approaching
runway advisory when I am at the hold-short line?
A. The Advisory is always provided at a fixed distance from
the runway edge at groundspeeds below 10 knots, and in
some cases the hold-short lines are not painted at positions
that correspond to ICAO standards. RAAS does not have
knowledge of ground markings. In RAAS RCDs with part
numbers ending -400 or later, a Pilot Point of View
(PPoV) distance compensation was added between the
nose of the aircraft and the runway edge.
Q. I received a Flaps Flaps alert while taxing on a runway
to my exit ramp, what caused this?
A. The Takeoff Flap Configuration Monitor will provide a
Flaps Flaps alert if aligned with the runway and Flaps
are not in takeoff configuration, 5 minutes after landing.
