At taxi speeds, which circuit is responsible for providing full braking action?

The option indicating the locked-wheel arming circuit is pertinent when considering full braking action at taxi speeds due to its purpose of engaging the brakes fully when a wheel begins to lock up. This circuit is designed to prevent wheel lock-up during braking, especially attractive during low-speed operations where maximum braking effectiveness is required without the risk of losing control.

At taxi speeds, it is crucial for the braking system to provide responsive braking while maintaining traction and control. The locked-wheel arming circuit activates to ensure that if any wheel starts to lose traction and lock up, the braking force can be optimized to maintain stability, allowing for effective deceleration.

The other circuits mentioned have alternate roles or are less critical for ensuring full braking action at taxi speeds. The anti-lock braking circuit, for instance, enhances vehicle control by preventing lock-up during more aggressive braking scenarios, but it does not specifically focus on providing full brake application in the way the locked-wheel arming circuit does.

The emergency braking circuit serves to provide extra braking capability in case of a failure in the primary systems, while the automatic brake system typically modulates the brakes for specific operational situations but does not emphasize full braking action at low speeds, where manual control often is prioritized.

Thus, the locked-wheel arming
