An emergency park brake system of an aircraft may include a user input interface configured to receive actuation input from a user. The emergency park brake system may also include a first displacement sensor and a second displacement sensor that are both coupled to the user input interface. The first displacement sensor may be configured to detect displacement of the user input interface and generate a first status of the user input interface and the second displacement sensor may be configured to also detect displacement of the user input interface and generate a second status of the user input interface. The emergency park brake system may also include a controller having a processor and memory. The controller may be configured to determine an emergency park brake condition.

Emergency park brake system

An electrically controlled park and emergency brake system is disclosed. The brake system may comprise a brake control module having a shut-off valve in fluid communication with an outboard servo-valve and an inboard servo-valve. An emergency/park power source may supply fluid to the shut-off valve. The brake system may also comprise a vehicle management system in electronic communication with the brake control module. The brake system may also comprise mechanical inputs, including a wheel well brake handle and a cockpit brake handle. The brake system may also comprise redundant emergency/park power sources.

Electrically controlled park and emergency valve assembly

A brake system is provided. The brake system may comprise a controller, a vehicle management system (VMS), a shut-off valve (SOV), an outboard valve (OBV), an inboard valve (IBV), a control module, an emergency/park power source, and a tangible, non-transitory memory configured to communicate with the controller. The VMS may be in communication with the controller. The control module may be in communication with the SOV, OBV, and IBV. The SOV may be in communication with the controller. The OBV may be in communication with the controller and in fluid communication with the SOV. The IBV may be in communication with the controller and in fluid communication with the SOV. The emergency/park power source may be in fluid communication with the SOV.
