Which action disengages the rudder pedal steering?

• A. Activation of the nosewheel steering
• B. Releasing the steering wheel
• C. Applying rudder pedal rapidly
• D. Turning off power to the hydraulic system

Answer: (A)

On the ground, nosewheel steering is often controlled separately from the rudder pedals. When nosewheel steering is activated, the steering system switches control away from the rudder pedals to the nosewheel steering mechanism. This prevents conflicting inputs and ensures the nosewheel follows the tiller or wheel command instead of the rudder pedals. So activating the nosewheel steering disengages the rudder pedal steering by design, allowing steering to be driven by the nosewheel system.

Releasing the steering wheel doesn’t switch modes, and rapidly applying the rudder pedals changes yaw but doesn’t disable the pedal steering. Turning off power to the hydraulic system could affect steering capability, but the specific disengagement mechanism described is the activation of nosewheel steering.
