slip at that value (best braking efficiency).
In normal operation, the reference speed is determined by the BSCU from the horizontal
acceleration of ADIRU 1, 2 or 3.
In case all ADIRUs fail, reference speed equals the maximum of either main landing gear wheel
speeds. Deceleration is limited to a default value of 1.7 m/s² (5.6 ft/s²).

ANTI-SKID SYSTEM
Applicable to:

,
MSN,,

The antiskid system provides maximum braking efficiency by maintaining the wheels at the limit of an
impending skid.
At skid onset, brake release orders are sent to the normal and alternate servovalves, as well as to
the ECAM system which displays the released brakes.
Full braking performance is achieved only with brake pedals at full deflection.
The antiskid system is deactivated below 20 kt (ground speed).
An ON/OFF switch activates, or deactivates, the antiskid and nosewheel steering systems.
PRINCIPLE
The speed of each main gear wheel (given by a tachometer) is compared to the aircraft speed
(reference speed). When the speed of a wheel decreases below approximately 0.87 times
(depending on conditions) reference speed, brake release orders are given to maintain the wheel
slip at that value (best braking efficiency).
In normal operation, the reference speed is determined by the BSCU from the horizontal
acceleration of ADIRU 1, 2 or 3.
In case all ADIRUs fail, reference speed equals the maximum of either main landing gear wheel
speeds. Deceleration is limited to a default value of 1.7 m/s² (5.6 ft/s²).

AUTO BRAKE - GENERAL
Applicable to: ALL
GENERAL
The purposes of this system are :
to reduce the braking distance ‐ in case of an aborted takeoff
‐ to establish and maintain a selected deceleration rate during landing, thereby improving
passenger comfort and reducing crew workload.
Applicable to:
MSN,
SYSTEM ARMING
The system arms when the crew presses the LO, MED, or MAX pushbutton switch if :
‐ Green pressure is available.
‐ The anti-skid system has electric power.
‐ There is no failure in the braking system.
‐ At least one ADIRS is functioning.
Note: Auto brake may be armed with the parking brake on.

braking will not activate because the ground spoilers will not extend.
For autobrake to activate, at least two SEC’s must be operative.
