Abstract

A method is disclosed that comprises severing an I/O channel between an EMAC and an aircraft component; sending a test signal to the brake system controller; receiving, from the brake system controller, a feedback signal to the test signal; and determining an appropriateness of the feedback signal.

Claims

1. A method for testing an electric brake system, the method comprising:

establishing a safety interlock between an electromechanical actuator controller “

EMAC”

and an aircraft component;

severing an I/O channel between the EMAC and the aircraft component;

sending at least one test signal to the EMAC;

receiving, from the EMAC, a feedback signal to the test signal; and

determining an appropriateness of the feedback signal; and

wherein in response to an emergency braking command from an emergency braking system, the EMAC ceases testing and issues a braking command in accordance with the emergency braking command independently of a command from a brake system controller (BSC) coupled to the EMAC.

2. The method of claim 1, further comprising reestablishing the I/O channel.

3. The method of claim 1, wherein the feedback signal relates to a least one of an electromechanical actuator and a servo.

4. The method of claim 1, wherein the test signal commands an electromechanical actuator to actuate.

5. The method of claim 1, further comprising generating a test script comprising a plurality of test signals with a testing module.

6. The method of claim 1, further comprising establishing a non-severable I/O channel between the EMAC and the emergency braking system.
