What is the maximum degree of nose gear rotation left or right of center with the torque link connected?

The maximum degree of nose gear rotation left or right of center with the torque link connected is 120°. This value is significant as it reflects the design specifications of the aircraft's landing gear system. The nose gear's ability to rotate within this range allows for adequate steering control on the ground while maintaining structural integrity during operations such as takeoff, landing, and taxiing.

A torque link, which connects the nose gear to the aircraft structure, ensures that the gear does not exceed its mechanical limits. This prevents excessive twisting forces that could lead to damage or failure. The 120° rotation permits sufficient maneuverability in tight spaces without compromising safety or performance.

The other options represent degrees of rotation that exceed what is mechanically safe and effective for typical aircraft operations. While greater rotation may seem beneficial for turning ease, it would risk the integrity of the landing gear assembly and the aircraft’s control systems. Hence, 120° is the engineered compromise between maneuverability and safety, making it the correct answer.
