Abstract: An emergency park brake system of an aircraft may include an electrical power interface, an electromechanical actuator, and a hydraulic brake valve. The electrical power interface may be configured to receive electrical power from a power source. The electromechanical actuator may be in selective power receiving communication with the electrical power interface and the electromechanical actuator may be mechanically coupled to and configured to selectively actuate the hydraulic brake valve. The electrical connection between the electromechanical actuator and the electrical power interface may be based on an emergency braking input.

Abstract: A method for brake health monitoring may include sending, by a brake control unit (BCU), a brake command signal to initiate a braking maneuver, and receiving a first wheel speed signal and a second wheel speed signal corresponding to the speed of first and second wheels, respectively, during the braking maneuver. The BCU may detect that the speed of the first wheel is greater than the speed of the second wheel by a predetermined threshold, and, in response thereto, post an alert indicating a failure in a brake control component associated with the first wheel based upon the detection of the speed of the first wheel being greater than the speed of the second wheel by the predetermined threshold.

Abstract: A braking system is disclosed. In various embodiments, the braking system includes a brake stack; an actuator configured to apply a compressive load to the brake stack; a servo valve coupled to a power source and to the actuator; and a brake control unit configured to operate the servo valve at a current ramp rate in response to a pedal deflection signal, wherein the current ramp rate is determined via a relationship between the current ramp rate and a brake pressure command signal.

Abstract: A BCU for determining a health status of a LRU having a coil includes a non-transitory memory configured to store instructions and a controller coupled to the non-transitory memory. The controller is designed to receive a temperature from a temperature sensor, to receive a direct current (DC) voltage that is applied to the coil of the LRU, and to receive a detected current corresponding to an amount of current flowing through the coil. The controller is further designed to determine a calculated resistance of the coil based on the detected current and the DC voltage and to determine a compensated resistance of the coil based on the temperature and the calculated resistance of the coil. The controller is further designed to determine the health status of the LRU by comparing the compensated resistance of the coil to a nominal resistance of the coil.
