• For final approach, speed will be selected to VLS on PFD. (which equates to VMCL-2 in case of
two engines inoperative on the same wing).
• When committed to land, speed may be managed. The magenta speed target drops to VAPP
i.e. below VLS on PFD. The ATHR must be disconnected and the speed reduced to VAPP
using manual thrust.

Note: In case of 2 engines failed on the same wing, VLS on the PFD takes into consideration
VMCL-2 whereas VAPP (displayed in magenta) and MCDU VLS do not take VMCL-2
into consideration.
In case of landing gear gravity extension (Engines 1+4 failed, or engines 2+3 failed),
the commit point will be at gear down selection. In the other cases, it will be when flying
below VMCL of the associated configuration on the approach.
TWO-ENGINE INOPERATIVE FLIGHT PATTERN
THRUST LEVERS MANAGEMENT IN CASE OF INOPERATIVE REVERSER(S)
Applicable to: ALL
PREFACE
This section provides recommendations on thrust levers management in case of inoperative
reverser(s). These recommendations are applicable in case of in-flight failure (including engine
failure) and/or in case of MEL dispatch with reverser(s) deactivated.
2AT LEAST ONE REVERSER OPERATIVE
If at least one reverser is operative, the general recommendation is to select the reverser thrust
on all (A340)/both (A330) engines during rejected takeoff (RTO) and at landing, as per normal
procedures.

Note: The ENG 1(2)(3)(4) (A340) REVERSER FAULT ECAM caution may be triggered after
the reverser thrust is selected. This is to remind the flight crew that reverser(s) is/are
inoperative.
NO REVERSERS OPERATIVE
If no reversers are operative, the general recommendation is to not select the reverser thrust
during RTO and at landing.
However, the PF still sets all (A340)/both (A330) thrust levers to the IDLE detent, as per normal
procedures.
BRIEFING
IMPORTANCE OF THE FLIGHT CREW BRIEFING
Among others, the aircraft status must be reviewed during the flight crew briefing. Any
particularities (operational consequences, procedures, associated task sharing and callout)
must be reviewed at that time. The flight crew must notably review:
• The status of the thrust reversers and if reverser thrust can be used
• Operational effect (aircraft handling during roll-out).

FMGC FAILURE
Applicable to: ALL
SINGLE FMGC FAILURE
Should a single FMGC failure occur, the AP, if engaged on affected side, will disconnect. The AP
will be restored using the other FMGC. The A/THR remains operative. Furthermore, flight plan
information on the affected ND may be recovered by using same range as the opposite ND. The
crew should consider a FMGC reset as detailed in QRH.
DUAL FMGC FAILURE
Should a dual FMGC failure occur, the AP/FD and A/THR will disconnect. The crew will try to
recover both AP and A/THR by selecting them back ON (The AP and A/THR can be recovered if
the FG parts of the FMGS are still available).
If both AP and A/THR cannot be recovered, the thrust levers will be moved to recover manual
thrust. The pilot will switch off the FDs and select TRK / FPA to allow the blue track index and the
bird to be displayed. The RMPs will be used to tune the navaids.
The crew will refer to the QRH for computer reset considerations and then will Refer to
FCOM/PRO-SUP-22-A AUTOMATIC FMGS RESET AND RESYNCHRONIZATION - FM RESET
to reload both FMGC as required.
If both FMGC cannot be recovered, the MCDU features a NAV B/UP function which provides
simplified IRS based navigation (Refer to FCOM/DSC-22_20-60-150 GENERAL). The FPLN is
still available as the MCDU continuously memorizes the active flight plan in its internal memory. It
should be noted that the FM source selector must be at NORM to allow the NAV/B/UP prompt to
be displayed on the MCDU MENU page.
