Section 6 Operational Availability - Honeywell EGPWS MK V Pilot's Manual

SECTION 6
Operational RAAS is operationally available anytime the EGPWS is
powered and the following conditions are met:
Availability
• The software for the RAAS functions have been loaded and
• The aircraft is on or approaching an airport in the RAAS
• RAAS is functional ( e.g., all external signals are available
RAAS operational availability is integrated into the existing

enabled into an EGPWS (with a minimum of software
version -218-218 (or later) and Terrain Database 435). For
RAAS with software version -230-230 (or later) Terrain
Database 454 (or later) is required;
runway database; and
and not faulted, GPS position accuracy meets minimum
RAAS requirements, there are no internal EGPWS faults).
EGPWS fault monitoring and self-test functions. Consistent
with approved EGPWS self-test design, the loss of RAAS
functions is indicated on-ground only during an EGPWS self-
test. There is no automatic annunciation of the loss of RAAS
functionality on most aircraft. The audio self-test messages
are as follows.
RAAS software enabled, functioning, has good position
information, and is at a validated airport. Feet will be
annunciated in the gender voice option (male or female)
selected for RAAS.
RAAS software enabled, functioning, has good position
information, and is at a validated airport. Metres will be
annunciated in the gender voice option (male or female)
selected for RAAS.
RAAS software enabled, but the system either has no
position information, the accuracy of the position
information is insufficient to allow RAAS to function, or
the aircraft is at an airport that has not been validated
for RAAS in the EGPWS Terrain Database.
RAAS software enabled, but the advisories have been
inhibited with the activation of an external discrete.
RAAS software enabled and functioning, but RAAS has
detected a Rejected Take-Off condition. To clear this
message, the aircraft must be taxied off the runway
area.
RAAS software enabled but function is inoperative.
