Claim 18:
19. An antiskid brake control system, comprising:
a brake control unit (BCU);
a wheel/brake assembly comprising a wheel, a brake stack, and an actuator configured to apply a braking force onto the brake stack; and
a wheel speed sensor in electronic communication with the BCU, the wheel speed sensor configured to detect a wheel speed corresponding to the wheel;
wherein the BCU is configured to:
receive an aircraft mass from an aircraft avionics unit;
calculate an aircraft speed based upon the wheel speed;
calculate an aircraft first kinetic energy during landing, prior to braking, using the aircraft mass and the aircraft speed;
determine a brake stack first coefficient of friction corresponding to the aircraft first kinetic energy;
responsive to determining the brake stack first coefficient of friction, generate an antiskid brake command signal based upon the brake stack first coefficient of friction;
send the antiskid brake command signal to a brake control component for controlling the braking force;
receive an updated wheel speed signal;
determine an updated aircraft speed based upon the updated wheel speed signal;
calculate an aircraft second kinetic energy during braking using the aircraft mass and the updated aircraft speed;
determine a brake stack second coefficient of friction corresponding to the aircraft second kinetic energy;
responsive to determining the brake stack second coefficient of friction, adjust the antiskid parameter based upon the brake stack second coefficient of friction;
generate a second antiskid brake command signal based upon the adjusted antiskid parameter; and
send the second antiskid brake command signal to the brake control component to apply a second stopping force to the wheel assembly.
