amount of time available for preparation.
ATC....................................................................................................................................NOTIFY
Notify ATC of the nature of the emergency and state intentions.
JETTISON......................................................................................................................CONSIDER
Consider fuel reduction to safe minimum. This reduces VREF and as a consequence the load
factor at impact and the energy to be dissipated.
If NOSE L/G abnormal
CG location (if possible)......................................................................................................AFT
10 passengers from front to rear move the CG roughly +2 % aft.
If one MAIN L/G abnormal
FUEL IMBALANCE................................................................................................. CONSIDER
Open all fuel crossfeed valves and switch off the pumps on the side with landing gear
normally extended.
OXYGEN CREW SUPPLY........................................................................................................OFF
SIGNS........................................................................................................................................ON
CABIN and COCKPIT..................................................................................................... PREPARE

LANDING GEAR
A330/A340 FLEET PRO-ABN-32 P 44/64
FCOM 19 AUG 10
LDG WITH ABNORMAL LG (Cont'd)
L/G LEVER .............................................................................................................CHECK DOWN
L/G GRVTY EXTN................................................................................................................RESET
AUTOBRAKE............................................................................................................ DO NOT ARM
Manual braking will enable better pitch and roll control. Moreover, with at least one main landing
gear in the abnormal position the autobrake cannot be activated (ground spoilers not armed)
EMER EXIT LT........................................................................................................................... ON
COMMERCIAL.........................................................................................................................OFF
CABIN REPORT..................................................................................................................OBTAIN
JETTISON................................................................................................................................OFF
T TANK FEED..........................................................................................................................ISOL
A/SKID & N/W STRG .............................................................................................................. OFF
With one main landing gear not extended, the reference speed used by the anti-skid to detect
a wheel blockage is not correctly initialized. As a result, the anti-skid must be switched off the
prevent permanent brake release.
MAX BRAKE PR.............................................................................................................. 1 000 PSI
Modulate the brake pressure to 1 000 PSI because the anti-skid is off.
If one or both MAIN L/G abnormal
GROUND SPOILERS.........................................................................................DO NOT ARM
To keep as much roll authority as possible for maintaining the wings level. Ground spoiler
extension would prevent spoilers from acting as roll surfaces.
BEFORE LANDING
RAM AIR ..................................................................................................................................ON
To ensure full depressurization of the aircraft before impact.
BRACE FOR IMPACT.........................................................................................................ORDER
FLARE, TOUCH DOWN AND ROLL OUT
Engines should be shut down sufficiently early to ensure fuel is shut off before the nacelles
impact, but sufficiently late to ensure adequate hydraulic supplies for the flight controls
Engine pumps continue to supply adequate hydraulic pressure for 30 s after engine shutdown.
