What is the role of the rudder pedals in the A320?

The rudder pedals in the A320 are primarily used to steer the aircraft on the ground, particularly during takeoff and landing operations. When the aircraft is taxiing, the rudder pedals can be manipulated to control the nose wheel steering. This steering capability allows the pilot to safely navigate the taxiways and runway while maintaining the desired path, especially during low-speed maneuvers.

In flight, the rudder pedals are also used for coordinated turns, helping to control yaw by moving the vertical stabilizer and thus affecting the aircraft's directional stability. While the rudder pedals contribute to overall aircraft control during flight, their main role is firmly rooted in ground operations for steering. Other options relate to functions that are not associated with the rudder pedals, reinforcing that their primary purpose is indeed for ground steering.
