Abstract: An aircraft brake system includes a supply line for supplying hydraulic fluid to wheel brakes, and an associated return line. Hydraulic fluid is replenished in at least a portion of the return line both before applying a braking force to the one or more wheels of the aircraft during landing, and before an intervening, optional, step if so performed of testing the brake system before landing of the aircraft. Replenishing the hydraulic fluid can be conducted by a control unit automatically and/or in response to a pressure drop in the return line measure by a transducer.

Abstract: An aircraft is disclosed including a ground manoeuvre control unit for automatically controlling ground manoeuvres. The aircraft has control mechanisms such as a rudder, nose wheel steering, spoilers, wheel brakes and the like for controlling motion of the aircraft. The control unit is configured to receive lateral input demands concerning lateral motion of the aircraft (e.g. heading control) and longitudinal input demands concerning longitudinal motion of the aircraft (e.g. deceleration). The control unit passes on the input demands as output demands to the relevant control mechanisms of the aircraft with, if so required, a modification which prioritises one of the lateral input demand and longitudinal input demand based on the risk of a lateral runway excursion and the risk of a longitudinal runway excursion.

Abstract: An aircraft brake control system for controlling antiskid braking of an aircraft wheel is disclosed including a control assembly having a mode controller which sets the mode of operation of an antiskid brake calculator, configured to set a first mode, when an input of the indication of a brake energy supply configuration indicates a first brake energy supply being used, in which the antiskid brake calculator applies a first restriction level on a rise rate of the antiskid brake command, and a second mode, when the input 305 indicates a second brake energy supply being used, in which the antiskid brake calculator applies a second, lower, restriction level on a rise rate of the antiskid brake command.

Abstract: A VTOL aircraft (100) including a wheel braking system and a hydraulically coupled shock absorber (5) and brake piston (7). The shock absorber (5) carries the weight of the aircraft (100) when a wheel (1) connected to the shock absorber (5) is in contact with a ground surface. A hydraulic pressure within the shock absorber (5) is proportional to the weight of the aircraft (100) carried by the shock absorber (5). The shock absorber (5) and brake piston (7) are hydraulically coupled such that, when the pressure within the shock absorber (5) exceeds a threshold pressure, the pressure within the shock absorber (5) actuates the brake piston (7) to apply a braking torque to the wheel (1) of the VTOL aircraft (100).

Abstract: A control device for an aircraft is disclosed including a push-button switch that is configured to be held in a depressed position by a pilot during taxiing of the aircraft. The push-button switch is configured to return automatically to a released position if it is not held in the depressed position by the pilot. The control device is configured to output a command for braking to a braking system of the aircraft, if the push-button switch moves to the released position during taxiing of the aircraft and does not return to the depressed position within a set time. The button may be provided on a tiller. A method of detecting on-board pilot incapacitation during an aircraft taxi phase is also disclosed.

Abstract: A method of parking an aircraft is disclosed including flight crew pedal braking to cause a brake force to be applied to the aircraft wheel brakes to slow the aircraft to a stationary state in which it is ready to be parked. Flight crew then activate a parking brake device and then release the pedal braking. An electronic control device, forming part of the aircraft’s braking system for example, automatically intervenes, following the manual release of the pedal braking, to cause a brake force to continue to be applied to the wheels. This may be until sufficient brake force is applied, as a result of the activation of the parking brake device, to hold the aircraft in its parked state or may be for a predetermined period of time, say, ten seconds.

Abstract: A speed determination system for an aircraft including one or more interfaces arranged to receive first speed data from a first speed measurement system and second speed data from a second speed measurement system. The first speed measurement system provides the first speed data using global positioning system data. The second speed measurement system provides the second speed data based on a second speed measurement. The speed determination system includes a processor arranged to determine whether the data received from the first speed measurement system is reliable. If global positioning data is determined to be reliable, the speed determination system determines a speed from the first speed data and determines correction values for the second speed measurement system. If global positioning data is determined to be unreliable, the speed determination system determines a speed from the second speed data and the correction values.

Abstract: A method of removing hydraulic fluid from an aircraft hydraulic system is disclosed including a hydraulically actuated mechanism that is actuated by an electrohydraulic servo valve, a hydraulic fluid port through which hydraulic fluid can escape, and a hydraulic fuse with a closed state and an open state between the electrohydraulic servo valve and the hydraulic fluid port. The hydraulic fluid port is opened, and then the activation of the electrohydraulic servo valve is controlled to force hydraulic fluid to escape from the hydraulic system via the hydraulic fluid port, the control being so that the hydraulic fuse does not enter and remain in the closed state.
