Electromechanical brake interlock

An aircraft, the aircraft comprising:

• an electromechanical brake system, the electromechanical brake system comprising:
• an electromechanical brake actuator, the electromechanical brake actuator comprising:
• an actuator motor configured to turn and apply a commanded clamping force;
• and
• an electromechanical brake actuator park brake configured to, responsive to being activated, maintain the commanded clamping force responsive to power to the actuator motor being turned off;
• an electronic brake actuator controller, the electronic brake actuator controller coupled to the electromechanical brake actuator;
• and
• an interlock, the interlock configured to receive a first signal from a park brake switch and a second signal from the electronic brake actuator controller, the interlock further configured to activate the electromechanical brake actuator park brake in response to the first signal from the park brake switch being activated and the second signal from the electronic brake actuator controller being activated.

A method of parking an electromechanical brake actuator of a brake assembly comprising:

• receiving a first signal from a park brake switch;
• receiving a second signal from software in an electronic brake actuator controller;
• and
• responsive to the first signal being activated and responsive to the second signal being activated, activating, via an interlock, an electromechanical brake actuator park brake in order to park the electromechanical brake actuator and maintain a commanded clamping force responsive to power to the actuator motor being turned off.
