    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 of performing prognostics on a hydraulic brake system of an aircraft may include determining, during primary braking mode and by a hydraulic brake controller, a first status of a first brake pressure sensor adjacent a brake assembly. The method may also include, in response to determining that the first status of the first brake pressure sensor is valid, determining, during park braking mode and by the hydraulic brake controller, a second status of a second brake pressure sensor adjacent a park valve assembly. In response to determining that the first status of the first brake pressure sensor is degraded, the method may include outputting, by the hydraulic brake controller, at least one of an inspection indicator and a maintenance indicator.

    Abstract: A wheel speed sensor may comprise a magnet; an induction coil coupled to the magnet; a rotor comprising a plurality of teeth, wherein the magnet is disposed proximate the plurality of teeth; a gear system coupled to the rotor comprising an initial gear, wherein the initial gear may be configured to be coupled to a wheel and configured to rotate at a speed equal to a wheel rotational speed of the wheel. The gear system may be configured to cause a rotor rotational speed of the rotor to be greater than the wheel rotational speed in response to the wheel rotating.

    Abstract: Braking control systems and methods, such as for an aircraft, use a first pressure sensor and a second pressure sensor from a non-primary braking system to validate the first pressure sensor. In response to the first pressure sensor being validated, a health status of a servo valve is monitored based on predetermined characteristics about the servo valve, including electrical current input into the servo valve and hydraulic pressure output from the servo valve.

    Abstract: A system for determining a deceleration rate of an aircraft, in various embodiments, includes at least one component capable of transmitting a first deceleration rate. The system also includes a brake control unit coupled to the at least one component and having a brake controller that is configured to receive the first deceleration rate from the at least one component and to determine a likely accurate deceleration rate based on the first deceleration rate, a second deceleration rate and a hierarchy of sources of deceleration rates.

    Abstract: Systems and methods for aircraft braking are disclosed. The systems and methods may comprise a control mode executive configured to receive a pedal input and calculate a gear deceleration command comprising a desired deceleration rate based on the pedal input; a pedal deceleration controller in electronic communication with the control mode executive configured to receive the gear deceleration command from the control mode executive and calculate a gear pedal command based on at least one of the gear deceleration command and a deceleration feedback; and a pedal executive in electronic communication with the pedal deceleration controller configured to receive the gear pedal command, and generate a pedal braking command based on the gear pedal command.

    Abstract: Systems and methods are disclosed herein for controlling braking systems. In this regard, a method for controlling brakes may comprise receiving, by an antiskid control (ASK), a first wheel speed, calculating, by the ASK, a first wheel reference speed (WRS), and calculating, by the ASK, a first wheel reference estimate (WRE). In various embodiments, the method may further comprise determining if the first WRS is within a threshold value of the first WRE. In various embodiments, the method may further comprise calculating an ASK desired pressure. The ASK desired pressure may be calculated using the first WRS in response to the first WRS being within the threshold value of the first WRE. The ASK desired pressure may be calculated using the first WRE in response to the first WRS being outside the threshold value of the first WRE.
