What system prevents the aircraft tires from locking up during landing?

The anti-skid system is designed to prevent aircraft tires from locking up during landing, which is essential for maintaining control and reducing stopping distances. When an aircraft lands, the wheels can sometimes stop rotating if the brakes are applied too hard, especially on wet or slippery runways. The anti-skid system monitors the speed of each wheel during landing and modulates the brake pressure applied to each tire. If a wheel starts to skid or lock up, the system reduces the braking pressure to that tire, allowing it to continue spinning. This not only prevents potential tire damage but also enhances the overall stability and control of the aircraft during the landing phase.

Other systems, such as the automatic braking system, assist with deceleration but do not specifically prevent tire lock-up, while wheel speed sensors are components that provide data for the anti-skid system but do not independently prevent locking. The hydraulic control system is responsible for actuating the brakes but does not directly relate to tire lock prevention.
