A330/A340 8.20.7 Operating Techniques
FCTM REV 1 (6 JUN 05)
Consider the use of TOGA thrust taking into account the following:
.
For a FLEX take-off, selecting the operating engine(s) to TOGA provides an additional performance margin, but is not a reduced thrust take-off certification requirement. The application of TOGA very quickly provides a large thrust increase. However, this comes with a significant increase in yawing moment and an increased pitch rate. The selection of TOGA restores thrust margins but it may increase aircraft handling workload
.
ALT/NAV mode changes may occur if TOGA is selected after the ALT pb is pressed with flaps/slats retracted. HDG mode will engage and command the aircraft heading at the time of TOGA selection
.
For a DRT take-off, asymmetric TOGA thrust must not be selected if the speed is below F speed in CONF 2 and 3 due to VMCA considerations. FCTM Ch 4 refers
.
TOGA thrust is limited to 10 minutes
The PNF closely monitors the aircraft's flight path and cancels any Master Warning or Caution. At 400 ft RA, the PNF reads the ECAM title displayed on the top line of the E/WD. Once the PF has stabilised the flight path, he confirms the failure. If it is necessary to delay the ECAM procedure, he orders "Standby". Otherwise he announces "I have control, ECAM actions". It is not necessary to rush into the ECAM actions and 400 ft RA is the minimum height at which commencement of the actions should be considered.
Normally, only those actions involving movement of the THRUST LEVER and/or ENG MASTER and those actions required to clear RED warnings are carried out prior to level acceleration and flap retraction. However, in the event of ENG FAILURE WITH DAMAGE or ENG FIRE, the ECAM procedure is continued until the engine is secured. For less critical failures, ECAM actions can be interrupted when necessary to allow both pilots to monitor normal operational requirements.
At the engine-out acceleration altitude, select ALT to level off and accelerate. If the aircraft is being flown manually, the rudder input needed to keep the . target centred reduces as airspeed increases. Retract the flaps as normal. When the flap lever is at zero, the . target reverts to the normal sideslip indication which should be centred conventionally using rudder. As the speed trend arrow reaches Green Dot speed in clean configuration, pull for OP CLB.
