How are braking systems typically integrated with landing gear?

Braking systems are typically integrated with landing gear by being controlled via the same hydraulic system for coordinated operation. This integration is essential for ensuring that braking can be effectively applied in conjunction with landing gear functions such as extension and retraction, as well as during the landing roll. Such a setup allows for smoother operation, where both systems can work together efficiently; for example, when the pilot applies brakes upon landing, the hydraulic system manages pressure to both the brake actuator and the landing gear components, optimizing performance and responsiveness.

This coordinated operation is crucial for safety and performance since it ensures that the aircraft can be stopped quickly and reliably on the ground. The hydraulic systems provide the necessary force to actuate the brakes effectively, allowing for a controlled deceleration based on the aircraft's needs.

The other choices overlook essential aspects of how braking systems are integrated with landing gear. For instance, independent operation would compromise the effectiveness and coordination needed during landing and taxiing, while manual inputs alone do not account for the automatic systems in modern aircraft that may engage braking in response to various conditions. Lastly, dependence solely on the aircraft's weight fails to recognize the role of hydraulic pressure in managing braking forces, which is vital for controlled deceleration.
