What could cause an anti-skid sensor failure and how would it affect braking?

• A. Sensor wiring fault or wheel speed sensor failure; braking may be less stable or misapplied
• B. The pilot can brake harder safely
• C. It has no effect on braking
• D. It improves braking stability

Answer: (A)

The main idea is that anti-skid (ABS) relies on wheel speed sensors to tell the brake control unit how fast each wheel is turning. If a sensor or its wiring fails, the system loses reliable speed information. Without accurate data, the controller can’t properly detect or prevent wheel lock, so it may misjudge when to apply or release brake pressure. The result is braking that is less stable and could be misapplied, potentially increasing stopping distance or allowing partial wheel lock. That’s why sensor or wiring faults degrade braking performance rather than making it safer or improving it.
