Abstract: Systems and methods for assessing runway conditions are disclosed. The system may comprise a brake control unit having an internal inertial sensor. The brake control unit may be configured to calculate a runway coefficient of friction to assess surface conditions of the runway. The brake control unit may monitor braking in an aircraft to detect a skid condition. In response to detecting the skid condition, the brake control unit may calculate an aircraft deceleration of the aircraft with the inertial sensor. The brake control unit may estimate the runway coefficient of friction based on the aircraft deceleration, an aerodynamic drag force of the aircraft, and a thrust reverse force of the aircraft.

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: Systems and methods for detecting an on ground condition of an aircraft are disclosed. A weight on wheel system may determine that an aircraft is on the ground. Wheel speed sensors may measure the speed of the aircraft wheels. Axle reference speeds may be calculated for each landing gear based on the speed of the aircraft wheels. A brake control unit may determine that the axle reference speed for each axle of the landing gears is above an on ground threshold speed, and the brake control unit may allow braking to be applied.

Abstract: A method of taxiing an aircraft may comprise determining, via a controller, whether the aircraft is taxiing with fewer brakes active than a total number of brakes; and modifying, via the controller, a brake pressure supplied to an active brake of the aircraft as a function of pedal deflection in response to determining the aircraft is taxiing with fewer brakes active relative to the total number of brakes.

Abstract: A braking system for an aircraft is disclosed herein. The braking system may comprise: a brake assembly; a hydraulic braking subsystem having a hydraulic brake actuator configured to operate the brake assembly; an electric braking subsystem and a hydraulic braking subsystem. During a flight, one of the electric braking subsystem and the hydraulic braking subsystem may be selected as a primary braking system. The braking system may be configured to command braking of a brake assembly by the hydraulic braking subsystem and the electric braking subsystem during an RTO phase of the flight. The braking system may be configured to command braking of a brake assembly by a secondary braking system in response to a failure of a primary braking system during the RTO phase of the flight.

Abstract: Systems and methods for antiskid brake control include a brake control unit (BCU) configured to generate a brake command signal adjusted for a wide range of brake coefficient of friction based upon a real-time aircraft kinetic energy value. A method for antiskid brake control includes receiving, by a BCU, an aircraft mass and a wheel speed signal. The BCU determines an aircraft speed based upon the wheel speed signal and calculates the aircraft kinetic energy using the aircraft speed and aircraft mass. One or more antiskid parameters (e.g., proportional gain, a derivative gain, and/or deceleration target value) are adjusted based upon the aircraft kinetic energy to generate, by the brake control unit, an optimal antiskid brake command signal.

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.
