MAIN WHEEL BRAKES.Aircraft wheel brakes may be applied by depressing the brake pedals. When either set of brake pedals are depressed, hydraulic pressure from both the left and right hydraulic brake system is applied to the main wheel brakes. A fully automatic, pressure modulating anti.skid system is installed. The system will reduce hydraulic pressure if necessary to prevent tire skidding and provide maximum braking. The anti-skid system is electrically controlled and has a touchdown wheel protection circuit that prevents braking action prior to main gear wheel spinup. When armed the automatic brake system (ABS) will automatically apply brakes during landing and takeoff. The anti-skid system must be armed and operational as a condition for ABS operation. ABS landing mode is activated when spoilers are deployed either automatically or manually with throttle levers retarded and brake pedals released. ABS takeoff mode is activated during a rejected takeoff upon deployment of ground spoilers provided the flaps are in takeoff range and the nose gear is on ground.
