A brake system is disclosed herein and includes a brake mode selection mechanism (204) configured to provide a desired braking command, an antiskid control mechanism (206) configured to provide an antiskid control braking command, and a brake executive mechanism (202). The brake executive mechanism (202) is configured to determine whether the antiskid control braking command is less than the desired braking command; responsive to the antiskid control braking command being less than the desired braking command, send a first command to implement the antiskid control braking command via an antiskid controller (208) configured to control a pressure or a force applied to a brake assembly; and, responsive to the desired braking command being less than the antiskid control braking command, send a second command to implement the desired braking command via a desired braking controller (210) configured to control the pressure or the force applied to the brake assembly.

A system for detecting an environmental condition at or adjacent a measurement location on an aircraft comprises a quantum sensor system configured to sense one or more physical parameters at the measurement location and to encode the sensed one or more physical parameters as one or more quantum states for quantum teleportation. It further comprises a processing system configured to receive the one or more quantum states from the quantum sensor system using quantum teleportation, and process the one or more quantum states to detect the environmental condition at or adjacent the measurement location.

A control system for a de-icing system for removing ice from an aircraft surface, the control system comprising: one or more sensors (3) configured to be mounted to or within an external surface (1b) of the aircraft surface, and to determine a change in sensed characteristic (40) that is indicative of ice shedding from the surface.

An attenuated brake roller assembly is provided. The attenuated brake roller assembly comprises a base (202), a cam member (204), a brake roller (206), and a compression spring (208). The cam member (204) coupled to the base (202), wherein the cam member (204) is coupled to the base (202) via a shaft that allows the cam member (204) to rotate in a clockwise direction and counterclockwise direction. The brake roller (206) coupled to the cam member (204). The compression spring (208) is disposed within the base (202). The compression spring (208) is configured to act on the cam member (204) such that, responsive to the brake roller (206) translating in a first direction, a compression spring force provided by the compression spring (208) causes the brake roller (206) to translate in a second direction opposite the first direction.

A method for controlling brake assemblies of a vehicle is provided. Responsive to identifying a locked wheel protection event for a first wheel of a paired set of wheels on the vehicle, where the paired set of wheels is the first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle, a first brake pressure to a first brake assembly (160a, 160b, 160c, 160d) associated with the first wheel is released to zero pounds per square inch (PSI) and a second brake pressure to a second brake assembly (160a, 160b, 160c, 160d) associated with the second wheel of the paired set of wheels is reduced by a predetermined amount thereby reducing a yaw effect to the vehicle.

A method for detecting an erroneous velocity data using a controller in communication with a velocity sensor (142) onboard a vehicle includes receiving a time-series velocity data from the velocity sensor (142), calculating a time-series acceleration data using the time-series velocity data, calculating a time-series jerk data using the time-series acceleration data, calculating a saturated (numerically bounded) jerk data using the time-series jerk data, calculating an estimated acceleration data using the saturated jerk data, calculating a difference between the estimated acceleration data and the time-series acceleration data, and determining whether the difference is greater than a threshold value. The erroneous velocity data is detected in response to the difference being greater than the threshold value.
