TAKEOFF
A318/A319/A320/A321
FLIGHT CREW TRAINING MANUAL
If the engine start selector had been selected to IGN START for take-off, the PNF should confirm with the PF when it may be deselected.
TAKE-OFF AT HEAVY WEIGHT
Applicable to: ALL
If take-off is carried out at heavy weight, two protections may intervene:
? The Automatic Retraction System (ARS)
? The Alpha Lock function
THE AUTOMATIC RETRACTION SYSTEM
While in CONF 1+F and IAS reaches 210 kt (VFE CONF1+F is 215 kt), the ARS is activated. The ARS automatically retracts flaps to 0 °. The VFE displayed on the PFD change from VFE CONF1+F to VFE CONF 1. As the aircraft accelerates above S speed, the flap lever can be selected to 0. If IAS decreases below VFE CONF1+F, the flaps will not extend back to 1+F.
THE ALPHA LOCK FUNCTION
The slats alpha/speed lock function will prevent slat retraction at high AOA or low speed at the moment the flap lever is moved from Flaps 1 to Flaps 0. "A. LOCK" pulses above the E/WD Slat indication. The inhibition is removed and the slats retract when both alpha and speed fall within normal values. This is a normal situation for take-off at heavy weight. If Alpha lock function is triggered, the crew will continue the scheduled acceleration, allowing further slats retraction.
IMMEDIATE TURN AFTER TAKE-OFF
Applicable to: ALL
Obstacle clearance, noise abatement, or departure procedures may require an immediate turn after take-off. Provided FD commands are followed accurately, the flaps and slats may be retracted using the normal procedure as FD orders provide bank angle limits with respect to speed and configuration.
LOW ALTITUDE LEVEL-OFF
Applicable to: ALL
If the aircraft is required to level off below the acceleration altitude, ALT* engages and target speed goes to initial climb speed. The "LVR CLB" message flashes on the FMA. In this case, the crew should expect a faster than normal acceleration, and be prepared to retract the flaps and slats promptly.
