Abstract
A system and procedures for setting a parking brake for an aircraft having an electric brake system are disclosed. Electric activation of a parking brake as described herein mimics the sequence of events that is performed to engage the parking brake of legacy hydraulic brake systems. The electric activation process obtains brake pedal deflection data and parking brake lever status data, and determines whether to set the parking brake mechanism based upon the received data. Once the electric brake actuators are set, the electric brake system engages a friction brake to hold the brake actuators in place without having to physically lock or latch the brake pedals in a depressed position.
