WARNING: IF STALL WARNING OCCURS DURING AN RA
MANEUVER, IMMEDIATELY ABANDON THE RA AND
EXECUTE STALL RECOVERY PROCEDURES. TCAS
II WILL CONTINUE TO PROVIDE RAS DURING STALL
WARNING AND RECOVERY PROCEDURE.
WARNING:
IF HIGH SPEED BUFFET IS ENCOUNTERED WHEN
INITIALLY RESPONDING TO AN RA, RELAX PITCH
FORCE AS NECESSARY TO REDUCE BUFFET, BUT
STILL CONTINUE TO MANEUVER.
NOTE: - The consequences of not following an RA may result in
additional RA's in which aural alert and visual annunciations
may not agree with each other.
- Using every available means, clear the airspace into which
you are going to maneuver. If needed, promptly and
smoothly adjust the airplane’s pitch to fly into the green
rectangle (if displayed), and fly out of the red trapezoidal
shaped avoidance zone(s). This should require no more than
0.75g to 1.25g maneuver (+-0.25g).
- Exaggerated responses to TCAS RAs are not desirable or
appropriate because of the other potential traffic conflicts
and ATC consequences. From level flight, proper response
to a TCAS RA typically results in an overall altitude deviation
of 300 to 500 ft to resolve a traffic conflict.
- If a CLIMB RA is issued with the airplane in the landing
configuration, a normal go-around should be initiated
including the appropriate thrust increase and configuration
change.
- Compliance with TCAS resolution advisories is required
unless the pilot considers it unsafe to do so.
- The pilot should promptly return to the previous ATC
clearance after the TCAS voice message "Clear of Conflict"
is announced.
- An immediate smooth response to a RA is required to obtain
maximum separations. TCAS II algorithms are based on the
pilot initiating the initial maneuver within 5 seconds of the RA
and within 2 1/2 seconds for additional corrective RA's
(increases or reversals). Any delay in responding to RA's will
reduce the separations provided.
