• With an aft CG and the pitch trim set to the nose-up limit the pilots will most probably have to
counteract an early autorotation until VR is reached.
In either case the pilot may have to modify his normal control input in order to achieve the
desired rotation rate, but should be cautious not to overreact.
CROSSWIND TAKEOFF
It is said in the TAKEOFF ROLL paragraph that care should be taken to avoid using large
deflection, resulting in excessive spoiler deployment.
A direct effect of the reduction in lift due to the extension of the spoilers on one wing will be a
reduction in tail clearance and an increased risk of tailstrike.
OLEO INFLATION
The correct extension of the main landing gear shock absorber (and thus the nominal increase
in tail clearance during the rotation) relies on the correct inflation of the oleos. An under inflated
oleo will delay the start of the bogie rotation and reduce tail clearances.
ACTION IN CASE OF TAILSTRIKE
If a tailstrike occurs at takeoff, flight at attitude requiring a pressurized cabin must be avoided and
a return to the originating airport should be performed for damage assessment.

AP ENGAGEMENT

The AP can be engaged 5 s after takeoff and above 100 ft RA.

SRS engages when the thrust levers are set to the applicable detent for takeoff and will remain
engaged until the acceleration altitude.
The SRS pitch command is the minimum of the following pitches:
• Pitch required to fly V2 +10 in All Engine Operative case (AEO)
• Pitch required to fly IAS at the time of failure (with minimum of V2 and maximum of V2 +15) in One
Engine Inoperative case (OEI)
• Pitch required to climb a 0.5 ° minimum climb gradient.
• Maximum pitch attitude of 17.5 ° (22.5 ° in case of windshear)
This explains why, during takeoff, the IAS which is actually flown in most cases is neither V2 +10
(AEO) nor V2 (OEI).

The SRS pitch command is the minimum of the following pitches:
Pitch required to fly V2 +‐ 10 in All Engine Operative case (AEO)
‐ Pitch required to fly IAS at the time of failure (with minimum of V2 and maximum of V2 +15) in One
Engine Inoperative case (OEI)
‐ Maximum pitch attitude of 15 ° (22.5 ° in case of windshear)
‐ Pitch required to climb a 0.5 ° minimum climb gradient.
This explains why, during takeoff, the IAS which is actually flown in 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 passengers’ 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 (eg; speed constraint, speed limit or ECON climb speed),
• Or to the preselected climb speed (entered by the pilot on PERF CLB page before takeoff).
