Patent Images
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, andwherein the severing of the I/O channel is responsive to a weight on wheels signal.

Abstract
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.

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. - View Dependent Claims (10, 11, 12, 13, 14)
