1. An aircraft brake control system, comprising:
left and right pilot-controlled brake pedals emitting first output signals corresponding to pilot-requested brake activity;
a first data source providing second output signals corresponding to aircraft parameters;
a second data source providing third output signals corresponding to brake control parameters;
a processing unit receiving said first, second and third output signals and determining therefrom an amount of yaw desired by the pilot and providing to left and right summers fourth output signals corresponding to said desired amount of yaw;
a source of data presenting an instantaneous yaw rate output signal to said left and right summers, said summers providing brake control signals adjusted to compensate for an actual yaw rate of the aircraft
left and right control signal generators connected to left and right controllers and limiters, said left and right controllers and limiters receiving said brake control signals;
said left and right control signal generators being further connected to and receiving signals from said left and right pilot-controlled brake pedals, along with other signals associated with particular brake operations, and being further connected to and providing output brake control signals to associated brakes; and
further comprising a safety path, disable signal generator and switches, interconnected with said left and right control signal generators.
