What does an anti-skid system primarily do during braking?

The anti-skid system plays a crucial role during braking by preventing wheel and tire assemblies from skidding. This system uses sensors to monitor the speed of individual wheels and detects when a wheel begins to lock up during braking. If a wheel is about to skid, the system automatically reduces brake pressure on that wheel, allowing it to continue rotating and maintain adhesion with the runway surface. This function is essential for maintaining control of the aircraft and avoiding loss of traction, which is critical for safe landings, especially on wet or slippery surfaces.

While other options may seem relevant, they do not accurately encapsulate the primary function of an anti-skid system. Enhancing braking force, prolonging brake life, and adjusting brake pressure automatically may be aspects related to braking systems in general, but they do not specifically define the primary purpose of the anti-skid system, which is focused on preventing skidding and ensuring optimal braking performance.
