and a red EICAS
message “PARK BRAKE ON” will be annunciated if the PARK/EMER BRAKE handle is set and
the airplane is in takeoff
parameters.

AUTOBRAKE SYSTEM
Autobrake function is provided for landing only. A flight compartment mounted AUTOBRAKE switch
provides selection of three deceleration levels and an “OFF” position. The switch is spring loaded to
the “OFF” position when not activated or disabled. The three deceleration levels are indicated as LO,
MED and HI.
AUTOBRAKE PANEL
AUTOBRAKE Switch
OFF − Inhibits the autobrake
function.
LO, MED and HI − Provides a
controlled rate of deceleration
based upon selection.

AUTO BRAKE
Deceleration rates are calculated from the reference wheel speed. If the rate difference is more than
a predetermined rate of knots, it will cancel the autobrake function and the switch will return to the
“OFF” position automatically.
All of the following conditions must be met to “arm” the autobrake and hold the switch in the selected
position:
· Switch selected to either LO, MED or HI.
· Airplane in the flight mode of operation (example: WOW indicating air).
· No deploy command for the ground spoilers.
· Brake pedal application less than 20% travel .
· Wheel speed at zero velocity.
· No autobrake or brake control faults.
The autobrake will apply when all of the following conditions are met:
· Autobrake switch selected to either LO, MED or HI.
· Wheel spinup
is active.
· Ground spoilers commanded to deploy.
The autobrake will “disarm” (release the deceleration control and command the AUTOBRAKE switch
to rotate to the “OFF” position) under any of the following conditions:
· Autobrake switch selected to “OFF” at any time.
· Brake pedal application of greater than 20% travel.
· Any autobrake or brake control fault during autobrake operation.
· Wheel speed signal invalid (determined by a comparison of channel A and B of the BCU).
· Ground spoilers stowed after having been deployed.
