The automatic braking system is responsible for locking the brakes during landing. This system enhances safety and operational efficiency by automatically applying the brakes to assist the flight crew in achieving the required deceleration upon touchdown. By using preset parameters, the automatic braking system engages based on factors such as aircraft speed and landing conditions, allowing for smoother and more controlled stops, especially in adverse weather conditions or short runways.

While other systems like the anti-skid, emergency brake, and hydraulic brake systems are integral to the overall braking function and safety mechanisms, they serve different purposes. The anti-skid system prevents wheel lockup during braking by modulating the brake pressure, thus promoting better control in slippery conditions. The emergency brake system is designed for use when standard braking systems fail, providing a backup method to decelerate the aircraft. The hydraulic brake system itself is the mechanism through which the braking force is applied but does not handle the automation aspect of braking during landing.

Understanding these distinctions highlights the role of the automatic braking system as the primary driver of brake application during landing operations, making it a critical element in modern aviation safety protocols.
