What is the maximum nosewheel steering angle achievable with rudder pedal only?

The maximum nosewheel steering angle achievable with rudder pedal inputs is typically determined by the aircraft's design and its steering systems. In many aircraft models, using the rudder pedals alone allows for precise control of the nosewheel during taxiing, takeoffs, and landings.

In this case, the correct answer is 25 degrees. This figure reflects a common design standard where rudder pedal input yields a limited steering angle, allowing pilots to maintain control without excessive maneuvering. It ensures that the nosewheel can pivot in conjunction with the aircraft's lateral movement, promoting stability and reducing the risk of ground looping or sudden directional changes.

Higher angles, such as 30 or 45 degrees, are often achievable using other control inputs, like the tiller or a combination of rudder and other systems. This emphasizes the importance of understanding the specific aircraft's capabilities and limitations regarding steering to operate it safely and effectively.

This context reinforces the usage of rudder pedals as the primary means for steering, with a well-defined limit that enhances pilot control during ground operations.
