What unit in an anti-skid system generates the anti-skid warning signal?

In an anti-skid braking system, the primary function of the control unit is to monitor the wheel speeds and determine when one or more wheels are about to skid. It processes the input data from various sensors associated with each wheel and assesses the braking efficiency. When an impending skid condition is detected, the control unit activates the warning signal to alert the flight crew. This warning signal is critical for providing real-time information about the skid condition, enabling the pilots to take necessary actions to maintain control of the aircraft.

The other components, while integral to the overall system, do not generate the anti-skid warning signal. The hydraulic pump provides the necessary hydraulic pressure for the braking system but does not communicate skid information. The warning light panel serves as a display for signals from the control unit, but it does not generate the warning itself. Similarly, the actuator is responsible for applying or releasing brake pressure based on commands from the control unit, but it does not generate the warning signal. Thus, the control unit is the component tasked with monitoring conditions and generating the necessary alerts in the anti-skid system.
