Which component ensures optimum braking under various runway conditions?

The anti-skid system is designed to prevent the wheels from locking up during braking, which can occur under various runway conditions such as wet or icy surfaces. This system uses sensors to monitor the rotation of each wheel and automatically modulates brake pressure to maintain optimal braking performance without skidding. By allowing the wheels to continue rotating while optimizing braking force, the anti-skid system helps maintain control and stability during landing and braking, thereby enhancing safety and performance.

The hydraulic control valves are important for regulating brake fluid pressure, but they do not adjust based on real-time conditions of the runway. The brake assembly refers to the physical components that create friction to slow the aircraft, but it does not dynamically adjust to different conditions. Wheel transducers provide data about wheel speed and contribute to the anti-skid system's function, but they are not the primary system ensuring optimum braking performance across varied conditions.
