Which statement about the anti-skid test procedure is true?

• A. It is not used in flight
• B. It is performed by built-in test function only
• C. It is performed by built-in test function and cycling the ANTI-SKID switch during originating check
• D. It requires maintenance action

Answer: (C)

The test checks anti-skid functionality by using both the built-in self-test and a manual check of the cockpit control. The built-in test function exercises the anti-skid controller, sensors, and hydraulics to confirm there are no faults. In addition, cycling the ANTI-SKID switch during the originating (preflight) check verifies that the system responds to the pilot control and can be engaged or disengaged as intended. This combination ensures both automatic diagnostics and proper control operation before flight. The procedure is typically performed on the ground as part of preflight checks and is not a maintenance action, and it’s not limited to flight operations.
