Patent ID: 8326506

Claim:
A method for controlling antiskid braking of a plurality of wheels in a group of wheels of an aircraft, said plurality of wheels having a corresponding plurality of wheel speed sensors associated therewith, respectively, said plurality of wheel speed sensors configured to generate wheel speed signals of said corresponding plurality of wheels, respectively, for antiskid control of said plurality of wheels, based upon said wheel speed signals, the method comprising the steps of: determining that a first wheel speed sensor of said plurality of wheel speed sensors associated with a corresponding first wheel of said plurality of wheels is not functioning to generate wheel speed signals; determining that a second wheel speed sensor of said plurality of wheel speed sensors associated with a corresponding second wheel of said plurality of wheels is functioning to generate wheel speed signals; determining a commanded braking pressure of said second wheel; determining whether an incipient or initial skid of said second wheel associated with said commanded braking pressure of said second wheel has occurred, based upon said wheel speed signals from said second wheel speed sensor; storing said commanded braking pressure of said second wheel as a brake pressure limit of said first wheel if said skid of said second wheel associated with said commanded braking pressure has occurred; determining a maximum brake pressure of said first wheel as a predetermined fraction of said brake pressure limit of said first wheel; determining a highest commanded braking pressure of said second wheel; storing said highest commanded braking pressure of said second wheel as said maximum brake pressure of said first wheel if an incipient or initial skid of said second wheel associated with said commanded braking pressure of said second wheel has not occurred; determining a modulated brake pressure as a second predetermined fraction of said maximum brake pressure of said first wheel; and providing modulated pressure pulses of the modulated brake pressure to said first wheel.
