Abstract: In an aircraft braking system comprising a plurality of carbon brakes a brake control system is provided whereby the number and/or proportion of brakes that may be disabled at each stage of a flight spectrum (i.e. taxi-out, take-off, in-flight, landing, taxi-in or stationary on the ground) and also the number and/or proportion applicable during each stage is further adjusted in response to the specific conditions applicable to the aircraft status at any given time thereby to ensure that the overall safety of the aircraft is not hazarded. The operation of the brake control system may be controlled at least in part by an on-board brake control implementation device actuated by a remote, land-based signal. The brake control system providing for use of less than the total number of available brakes during the landing stage of the flight spectrum.
