Systems and methods for built in test equipment for a brake control system
A method is disclosed that comprises severing an I/O channel between a brake system controller 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. A system is disclosed that comprises a brake system controller wrapped in a BITE region, wherein the BITE region comprises a testing module, a safety interlock region having an I/O channel between the brake system controller and another system, and a testing module capable of sending a test signal to the brake system controller.
1. A system comprising:
a brake system controller wrapped in a BITE region, wherein the BITE region comprises a testing module; and
a safety interlock region having an I/O channel between the brake system controller and another system,
wherein the testing module is capable of sending a test signal to the brake system controller,
wherein the BITE region reversibly severs an I/O channel between the brake system controller and another aircraft component, and
wherein the severing of the I/O channel is responsive to a weight on wheels signal.
2. The system of claim 1 , wherein the testing module receives a signal from a component of the brake system controller.
3. The system of claim 1 , wherein the safety interlock region is in electrical communication with the testing module.
4. The system of claim 3 , wherein the testing module creates a test script.
5. A system comprising:
a brake system controller wrapped in a BITE region, wherein the BITE region comprises a testing module; and
a safety interlock region having an I/O channel between the brake system controller and another system,
wherein the testing module is capable of sending a test signal to the brake system controller,
wherein the BITE region reversibly severs an I/O channel between the brake system controller and another aircraft component,
wherein the severing of the I/O channel is responsive to at least one of a landing gear downlock signal and a throttle position signal.
6. The system of claim 5 , wherein the testing module receives a signal from a component of the brake system controller.
7. The system of claim 5 , wherein the safety interlock region is in electrical communication with the testing module.
8. The system of claim 7 , wherein the testing module creates a test script.
9. A method comprising:
disposing a selectively severable I/O channel between a brake system controller and an aircraft component;
coupling the brake system controller with a BITE region, wherein the BITE region comprises a testing module capable of sending a test signal to the brake system controller;
establishing a safety interlock region by disposing a non-severable I/O channel between the brake system controller and the aircraft component; and
severing the selectively severable I/O channel between the brake system controller and the aircraft component in response to a weight on wheels signal.
10. The method of claim 9 , further comprising placing the safety interlock region in electrical communication with the testing module.
11. The method of claim 9 , further comprising loading a test script into the testing module.
12. The method of claim 9 , further comprising loading an expected result profile into the testing module.
13. The method of claim 9 , further comprising placing the BITE region in electrical communication with a signal conditioning circuit.
14. The method of claim 9 , further comprising placing the BITE region in electrical communication with a sensor.
