What is the maximum nosewheel steering angle when using rudder pedals and differential braking?

The maximum nosewheel steering angle when using rudder pedals and differential braking is 45 degrees. This configuration allows for enhanced maneuverability during ground operations, particularly during taxiing and low-speed turns.

The use of rudder pedals in tandem with differential braking enables the pilot to make tighter turns without risking excessive lateral forces that could compromise aircraft stability. In this limit, utilizing both control methods helps maintain ground handling effectiveness while ensuring the aircraft remains controllable. The specific limitation of 45 degrees is often derived from both regulatory guidelines and the aircraft's design specifications, ensuring that the capabilities are within safe operational parameters.

In contrast, lower angles of steering, such as 25 or 35 degrees, might not provide optimal agility when maneuvering the aircraft, while a maximum of 60 degrees would likely exceed safe operating limits, risking structural damage or loss of control. Thus, 45 degrees strikes an appropriate balance for effective and safe ground handling.
