05 - TRAINEES’ ACTIONS
The conventional stall is only possible in alternate and direct control laws, because of the protections provided in normal law. Alternate or direct law will be indicated by ECAM and the changes on the PFD ; bank angle and pitch limitation replaced by amber X, low speed indications change from alpha prot. to VSW. VSW is load factor dependant and will increase with increase in pitch up rate or bank angle.
Also, an aural warning is produced on entering the stall regime. This aural warning is produced by the AOA sensors not the FACs. It is possible to experience "false warnings" if pitch control is rough during the recovery from the stall. VSW indications are always correct as these are generated by the FACs.
INDICATION ........................................................................................"STALL, STALL, STALL"
THRUST LEVERS...............................................................................TOGA

At the same time :
PITCH ATTITUDE................................................................................REDUCE
BANK ANGLE......................................................................................ROLL WINGS LEVEL
SPD BRAKES......................................................................................CHECK RETRACTED

If a danger of ground contact exists, reduce pitch attitude no more than necessary to allow
airspeed to increase.
After initial recovery, maintain speed close to VSW until it is safe to accelerate.

If below 20,000 ft, and in clean configuration, select CONF 1.
Out of stall when there is no threat of ground contact:

LANDING GEAR..................................................................................UP

Recover to normal speed and retract flaps as required.
In case of engine inoperative, use power and rudder with care.
Be prepared for a strong pitch up due to power application and the need for large manual
pitch trim changes in DIRECT law.
Care must be exercised not to re-enter the stall regime and set off another warning. With
prompt action, very little height is lost.

06 - COMPLETION STANDARDS
.
Takes immediate action at first indication of impending stall.

.
Employs correct recovery technique and ensures minimum altitude loss.

07 - COMMON ERRORS
.
Recovery not initiated immediately.

.
Insufficient pitch control at desired attitude.

.
Stall re-entry due to uncontrolled high pitch attitude.

.
Use of manual trim below VLS.

.
Clean up before acceleration above VLS.

.
To manually control the aircraft in abnormal flight control laws.

.
To carry out ECAM and QRH procedures respecting task sharing requirements.

.
To safely perform approach and landing in abnormal configuration.
