NORMAL OPERATIONS
TAKEOFF
A318/A319/A320/A321
FLIGHT CREW TRAINING MANUAL
This explains why, during takeoff, the IAS which is actually flown in most cases is neither V2+10 (AEO) nor V2 (OEI).
LATERAL PROFILE
Applicable to: ALL
Under most circumstances, the crew can expect to follow the programmed SID. In this case, NAV is armed on selecting the thrust levers to the applicable detent for take-off and engages once above 30 ft RA.
THRUST REDUCTION ALTITUDE
Applicable to: ALL
At the thrust reduction altitude, "LVR CLB" flashes on the FMA. When manual flying, lower slightly the nose, as applicable, to anticipate the pitch down FD order. Bring the thrust levers back to CLB detent. The A/THR is now active (A/THR on the FMA changes from blue to white).
The FD pitch down order depends upon the amount of thrust decrease between TOGA or FLX and CLB.
If takeoff was performed packs OFF, the packs will be selected back to ON after thrust reduction because of the potential resulting EGT increase. They will be preferably selected sequentially to improve passenger's comfort.
ACCELERATION ALTITUDE
Applicable to: ALL
At the acceleration altitude, the FD pitch mode changes from SRS to CLB or OP CLB mode. The speed target jumps:
? Either to the managed target speed e.g. speed constraint, speed limit or ECON climb speed
? Or to the preselected climb speed (entered by the pilot on the MCDU PERF CLB page before takeoff).
If green dot speed is higher than the managed target speed (e.g. speed constraint 220 kt) displayed by the magenta triangle on the PFD speed scale, the AP/FD will guide the aircraft to green dot (as per the general managed speed guidance rule). If required by ATC, the crew will select the adequate target speed (below green dot) on the FCU.
