actuators, thereby reducing the probability of gear collapse after touchdown.
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
CABIN REPORT..................................................................................................................OBTAIN
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 to
prevent permanent brake release.
MAX BRAKE PR.................................................................................................................1000PSI
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
If the external light condition is poor at landing:
DOME LT.............................................................................................................................DIM
Set the dome light to DIM to ensure that there is a light source after both engines are shut
down after landing, in order to see and read the BRAKE PRESS indicator.
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.
REVERSE..................................................................................................................DO NOT USE
Do not use reverse in order to prevent:
The engine(s) from touching ‐ the ground during rollout

LDG WITH ABNORMAL L/G (Cont'd)
‐ Ground spoilers extension, in the case of abnormal main landing gear.
If NOSE L/G abnormal:
NOSE..................................................................................................................MAINTAIN UP
After touchdown, keep the nose off the runway by the use of the elevator. Then, lower the
nose on to the runway before elevator control is lost.
BRAKES (compatible with elevator efficiency)...............................................................APPLY
ENG MASTERS..................................................................................................................OFF
Shutdown the engines before nose impact.
If one MAIN L/G abnormal:
ENG MASTERS..................................................................................................................OFF
At touchdown, shut down both engines.
FAILURE SIDE WING........................................................................................ MAINTAIN UP
Use roll control, as necessary, to maintain the unsupported wing up as long as possible.
DIRECTIONAL CONTROL....................................................................................... MAINTAIN
Use rudder and brakes (maximum 1 000 PSI) to maintain the runway axis as long as
possible.
If both MAIN L/G abnormal:
ENG MASTERS..................................................................................................................OFF
Shut down the engines in the flare, before touchdown.
PITCH ATTITUDE (at touchdown)........................................................... NOT LESS THAN 6°
WHEN A/C STOPPED
ENG (all) and APU FIRE pushbutton.....................................................................................PUSH
