A330/A340 Take-off And Initial Climb
REV 1 (6 JUN 05)
FCTM Initial Climb
The Alpha Lock Function
The slats alpha/speed lock function will prevent slat retraction at high AOA or low speed at the moment the flap lever is moved from Flaps 1 to Flaps 0. “A LOCK” pulses in green above the E/WD slat indication. This is possible if maneuvering during a heavy weight take-off. Continue with the scheduled acceleration that will eventually trigger slats retraction.
The inhibition is removed and the slats retract when both alpha and speed fall within normal values. This protection feature is no longer available once the flap lever has been selected to zero.
TRACKING THE LOCALISER OF THE OPPOSITE RUNWAY
If the aircraft is required to track the localiser of the opposite runway, the ILS must be correctly set on the MCDU RADNAV page to allow monitoring of localiser deviation in the correct sense.
If the ILS is in the database, the FMGC should automatically tune the correct frequency and course, which should be the take-off runway course preceded by a “B”.
If the ILS is not stored in the database or the FMGC fails to tune the correct frequency and course, manually insert the ILS frequency (or ident), and the take-off runway course preceded by a “B”. For example, if the ILS frequency and associated course of the opposite runway were 109.9/073°, and the take-off direction was therefore 253°, insert frequency 109.9 and course B253. “B/C” will be displayed on the ND (ROSE LS) and PFD (LS) in magenta.
If the RWY/ILS MISMATCH message is displayed in the MCDU scratchpad, it may be disregarded.
Use NAV mode for departure and monitor localiser tracking on the PFD by pushing the LS pb on the EFIS CTL panel, or on the ND by selecting ROSE LS. Both the PFD and ND will display localiser deviation in the correct sense. Do not select the LS pb on ISIS, since the ISIS displays localiser deviation in the reverse sense.

LOW ALTITUDE LEVEL-OFF
If the aircraft is required to level-off below the acceleration altitude, ALT* engages and SRS disengages. The "LVR CLB" message flashes on the FMA and the target speed goes to the initial climb speed. Thrust levers should be selected to the CLB detent to engage SPEED mode. In this case expect a faster than normal acceleration and be prepared to retract the flaps and slats promptly.
CLOSE-IN TURN AFTER TAKE-OFF
Where limited acceleration is required to comply with SID tracking or altitude requirements, pre-select a suitable speed in the PERF CLB page. The pre-selected speed should be above F speed to allow initial flap retraction to CONF 1. Delaying the acceleration by inserting a higher ACCEL ALT in the MCDU is not recommended.
