Maintain runway centeline with rudder pedals, the stick remaining neutral (unless very strong crosswinds or very aft CG). This is because any sidestick displacement will cause the spoilers to deploy. By 130 kt, the connection between nosewheel steering and rudder pedals is removed, and more rudder input will gradually be required to prevent the aircraft turning into wind.
At VR, rotate the aircraft smoothly to 5° nose up, thereafter follow SRS. During this time the control laws will change to flight mode. Above 30 ft auto pilot is available.
A positive rate of climb should be confirmed on altimeter, VSI and RA before requesting retraction of the undercarriage.
Good technique is required in order to avoid tail strike, particularly on the A321. Early rotation, over-rotation and excessive pitch rate (or any combination) may all cause a tailstrike on take-off (refer to FCOM bulletin 22). In the event of a tail strike, flight at high altitude is not recommended and an immediate return should be considered.
At thrust reduction altitude, reduce aircraft pitch attitude, and with a positive speed trend, reduce thrust to the climb gate. Check FMA annunciation’s and retract flaps on schedule. The F and S speeds are minimum speeds for flap retraction and not speeds at which retraction is essential. Ensure a positive speed trend before flap retraction. When accelerating through 210 kts with CONF 1 + F selected, the flaps will automatically retract to CONF 1, well before VFE of 215 kts. Flaps will not automatically re-extend if speed drops below 210 kts (FCOM 1.27.50 [Flight Controls - Flaps and Slats]). Complete after take-off items and then the after take-off checklist.
If a packs off take-off was carried out, PACK 1 should be selected on at thrust reduction and PACK 2 when the flaps have been retracted.

01 - TRAINING OBJECTIVE
.  To apply correct technique for take-off when crosswind exceeds 20 kts.
02 - SCHEDULE
Briefing duration : 5 minutes
03 - EQUIPMENT
DOC references :
.  FCOM 3.03.12 (Procedure)
04 - INSTRUCTOR’S ACTIONS
Briefing of the following key points.
MAIN
.  
Stick / Thrust lever procedure.

.  
Use of into wind aileron.

05 - TRAINEES’ ACTIONS
In cases of strong crosswind and or tailwind, the following technique is recommended :
.  At commencement of the take-off roll, apply full forward stick. Move the thrust levers progressively to reach FLEX/TOGA power by 40 kts. Small inputs on the sidestick laterally may be made, although too large an input will cause spoiler deployment. During rotation, the stick should be centralized so that the aircraft gets airborne with zero roll rate demand.
