Which unit generates the anti skid warning light signal?

• A. The anti skid control unit
• B. Wheel speed sensor
• C. Master warning switch
• D. Brake accumulator

Answer: (A)

In an anti-skid system, the warning light is driven by the anti-skid control unit. This unit watches the whole system—wheel speed sensor data, hydraulic pressure, sensor integrity, and actuator function—and decides when something is out of range or faulty. If it detects a problem, it activates the warning light to alert the crew. The wheel speed sensors only feed data to the control unit; they don’t generate the warning signal themselves. The master warning switch is just a cockpit indicator control, not a signal source, and the brake accumulator stores hydraulic pressure but doesn’t trigger warnings. So the anti-skid control unit is the component that generates the anti-skid warning light signal.
