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 select the gear up.
AP ENGAGEMENT
The PA can be engaged 5 seconds after take-off and above 100 ft RA Trim the aircraft and safety the FD commands prior to AP engagement, this will prevent undesirable excursions from the desired flight path.
VERTICAL PROFILE
SRS Engine 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 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, the 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.
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 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.
