ABSTRACT:
Test circuitry for exercising and testing the operability of antiskid and automatic braking control circuits in an aircraft braking system. The invention includes a digital processor communicating with an interface circuit associated with each antiskid control circuit and the automatic braking system valve drivers. Each such interface circuit includes an analog switch receiving an electrical stimulus from the processor and applying the same to various test points in the associated antiskid control circuit or automatic braking system valve drivers. An analog selector is connected to various test points in the antiskid control circuits and automatic braking system valve drivers to sense the responses to the electrical stimulus and to pass such responses to the processor to determine the operability of the antiskid and automatic braking control systems.
