The following voice messages annunciate enhanced TCAS maneuvers when the initial
TCAS RA does not provide sufficient vertical separation. The tone and inflexion must
constate increased urgency.
"INCREASE DESCENT, INCREASE DESCENT"
:
(descend at the rate depicted by the green (fly to) arc on the TCAS VSI). Received
after DESCEND" advisory, and indicates additional descent rate required to achieve
safe vertical separation from a maneuvering threat aircraft.
INCREASE CLIMB, INCREASE CLIMB" :
(climb at the rate depicted by the green (fly to) arc on the VSI). Received after CLIMB"
advisory, and indicates additional climb rate required to achieve safe vertical
separation from a maneuvering threat aircraft.
CLIMB-CLIMB NOW, CLIMB-CLIMB NOW" :
(climb at the rate depicted by the green (fly to) arc on the TCAS VSI). Received after a
DESCENT" resolution advisory and indicates a reversal in sense is required to
achieve safe vertical separation from a maneuvering threat aircraft.
DESCEND-DESCEND NOW, DESCEND-DESCEND NOW" :
(descend at the rate depicted by the green (fly to) arc on the TCAS VSI).
Received after a CLIMB" resolution advisory and indicates a reversal is required to
achieve safe vertical separation from a maneuvering threat aircraft.
All TCAS aural alerts are inhibited :
- below 1100 ft AGL when aircraft is climbing.
- below 900 ft AGL when aircraft is descending.
