Abstract: A system for two-stage determination of a brakefail of an aircraft brake system includes an aircraft brake. The aircraft brake is configured to receive a current command value, convert the current command value to a braking pressure and output a detected pressure value corresponding to the braking pressure. The system also includes a brake control unit (BCU) configured to determine a pressure command value, convert the pressure command value to the current command value and to determine whether a brakefail event has occurred based on the pressure command value, the current command value and the detected pressure value.

Abstract: A method for controlling brakes is provided. The method may include the steps of detecting an aircraft speed, determining the aircraft speed is within a range from an antiskid-dropout speed to a locked-wheel-protection-engagement speed, and determining an input of a pressure controller has a value less than a pressure maximum threshold. A current command that is output from the pressure controller may be detected at or above a threshold value. The states of the pressure controller and pressure controller input may be reset in response to the current command being at or above the threshold value for a predetermined duration.
