When the alpha floor protection is triggered, the A/THR triggers TOGA on all engines. The FMA displays A FLOOR, that changes to TOGA LK, when the aircraft angle-of-attack has decreased. TOGA/LK can only be deselected by turning the A/THR off.
The SRS pitch mode ensures the best aircraft climb performance. Therefore, the procedure requests following the SRS pitch bar and possibly full aft stick, in order to follow the SRS orders and minimize the loss of height.
The high angle-of-attack protection enables the PF to safely pull full aft stick, if needed, in order to follow the SRS pitch order, or to rapidly counteract a down movement. This provides maximum lift and minimum drag, by automatically retracting the speed brakes, if they are extended.

OPERATIONAL RECOMMENDATIONS
TAKE-OFF
Predictive windshear ("WINDSHEAR AHEAD" aural warning), if available
If predictive windshear aural warning is generated on the runway before take-off, take-off must be delayed.
If a predictive windshear aural warning is generated during the takeoff roll, the Captain must reject the takeoff (the aural warning is inhibited at speeds greater than 100 kt).
If the predictive windshear aural warning is generated during initial climb, the flight crew must:
? Set TOGA
? Closely monitor the speed and the speed trend
? Ensure that the flight path does not include areas with suspected shear
? Change the aircraft configuration, provided that the aircraft does not enter windshear.
Reactive windshear (WINSHEAR, WINSHEAR, WINSHEAR aural warning) or windshear detected by pilot observation
If the windshear starts before V1 with significant speed and speed trend variations and the captain decides that there is sufficient runway to stop the airplane, the captain must initiate a rejected take-off.
If the windshear starts after V1, the crew will set TOGA and will apply the QRH checklist actions from memory. The following points should be stressed:
? The configuration should not be changed until definitely out of the shear, because operating the landing gear doors causes additional drag.
? The PF must fly SRS pitch orders rapidly and smoothly, but not aggressively, and must consider the use of full backstick, if necessary, to minimize height loss.
? The PNF should call wind variation from the ND and V/S and, when clear of the shear, report the encounter to ATC.
APPROACH
Predictive windshear (if available)
In case the "MONITOR RADAR DISPLAY" is displayed or the ADVISORY ICON appears, the flight crew should either delay the approach or divert to another airport. However, if the approach is continued, the flight crew should consider the following:
? The weather severity must be assessed with the radar display.
