FCTM A318/319/329/321 SUPPLEMENTARY INFORMATION
If a TA is generated:
. The PF announces: «TCAS, I have controls».
. The PF flies and announces the bearing and distance displayed on his ND.
. The PNF looks outside to get visual contact.
No evasive maneuver should be initiated, only on the basis of a TA
If a RA is generated:
. The flight crew must always follow the TCAS RA orders in the correct
direction, even:
— If they contradict the ATC instructions
— At the maximum ceiling altitude with CLIMB, CLIMB or INCREASE CLIMB,
INCREASE CLIMB TCAS RA orders
— If it results in crossing the altitude of the intruder.
. The PF disconnects the AP, and smoothly and firmly follows the Vertical
Speed Indicator (VSI) green sector within 5 seconds, and requests that both
FDs be disconnected.
Note: Both FDs must be disconnected once APs are disconnected:
— To ensure autothrust speed mode
— To avoid possible confusion between FD bar orders and, TCAS aural
and VSI orders
. The PNF disconnects both FDs, but will not try to see intruders.
. The PF will avoid excessive maneuvers, and keep the Vertical Speed outside
the red area of the VSI and within the green area. If necessary, the PF must
use the full speed range between Valpha max and Vmax.
. The PNF must notify ATC.
. The flight crew should never maneuver in the opposite direction of the RA,
because TCAS maneuvers are coordinated.
