Claim 11:
12. An antiskid brake control system, comprising:
a brake control unit (BCU) having a processor; and
a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the BCU to perform operations comprising:
receiving, by the BCU, an aircraft mass;
receiving, by the BCU, a wheel speed signal;
determining, by the BCU, an aircraft speed based upon the wheel speed signal;
calculating, by the BCU, an aircraft first kinetic energy during landing, prior to braking, using the aircraft mass and the aircraft speed;
determining, by the BCU, a brake stack first coefficient of friction corresponding to the aircraft first kinetic energy;
responsive to determining the brake stack first coefficient of friction, adjusting, by the BCU, an antiskid parameter based upon the brake stack first coefficient of friction;
generating, by the BCU, an antiskid brake command signal based upon the adjusted antiskid parameter;
sending, by the BCU, the antiskid brake command signal to a brake control component for applying a stopping force to a wheel assembly;
receiving, by the BCU, an updated wheel speed signal;
determining, by the BCU, an updated aircraft speed based upon the updated wheel speed signal;
calculating, by the BCU, an aircraft second kinetic energy during braking using the aircraft mass and the updated aircraft speed;
determining, by the BCU, a brake stack second coefficient of friction corresponding to the aircraft second kinetic energy;
responsive to determining the brake stack second coefficient of friction, adjusting, by the BCU, the antiskid parameter based upon the brake stack second coefficient of friction;
generating, by the BCU, a second antiskid brake command signal based upon the adjusted antiskid parameter; and
sending, by the BCU, the second antiskid brake command signal to the brake control component to apply a second stopping force to the wheel assembly.
