Initial Climb
FCTM REV 1 (6 JUN 05)
PREFACE
For the purpose of this manual, initial climb is considered to be from the take-off through to the completion of flap retraction.
LIFT-OFF
A positive rate of climb should be confirmed on the VSI and RA before ordering "Gear Up". After confirming increasing RA and positive V/S, the PNF calls "Positive Rate, Gear Up" and then selects the gear up.
AP ENGAGEMENT
The AP can be engaged 5 seconds after takeoff and above 100 ft RA. Trim the aircraft and satisfy the FD commands prior to AP engagement. This will prevent undesirable excursions from the desired flight path.
VERTICAL PROFILE
SRS engages when the thrust levers are set to the FLEX/TOGA detent for take-off and will remain engaged until the acceleration altitude. SRS orders provide a speed target of V2+10 (or with one engine inop, the IAS at the time of failure with a minimum of V2 and a maximum of V2+15), but within pitch and gradient limits. Consequently, it is possible that the IAS demanded by the FDs may be higher than V2+10 (or V2 with one engine inop).
LATERAL PROFILE
Under most circumstances, 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.
ATC may require the aircraft to maintain a specific heading after take-off. In this case, and prior to commencing the take off roll, turn the FCU HDG selector to the required heading. This process will disarm NAV. Once airborne and above 30 ft RA, RWY TRK engages. When required, pull the FCU HDG knob to establish the required heading.

FCTM Initial Climb
THRUST REDUCTION ALTITUDE
At the thrust reduction altitude, "LVR CLB" flashes on the FMA. Follow the FD pitch command before selecting the thrust levers to the CL detent, at which point A/THR becomes active. The FD pitch down order depends on the amount of thrust decrease between TOGA /FLEX and CLB.
Following thrust reduction with all engines operating, the PNF selects Pack 1 on, pauses 5 to 10 sec, and then selects Pack 2 on. With an engine failure before thrust reduction altitude, this procedure is delayed until MCT is set and the aircraft climbing at Green Dot.
ACCELERATION ALTITUDE
At the acceleration altitude, the FD pitch mode changes from SRS to CLB, (or OP CLB if HDG were pre-selected prior to take off). The speed target becomes either the preset climb speed, if one had been entered on the PERF CLB page, or the managed climb speed. At heavy weights, Green Dot speed is normally higher than the managed speed target. In this case, when Flaps 0 is selected, the aircraft will accelerate past the managed speed target to Green Dot.
The minimum speed for moving the flap lever to 1 is displayed as F on the PFD speed tape. The minimum speed for moving the flap lever to 0 is displayed as S on the PFD speed tape. The PNF positively cross checks that the speed is above the minimum before moving the flap lever.
