How much nosewheel steering authority does the pilot have through the rudder pedals?

The amount of nosewheel steering authority that a pilot has through the rudder pedals is typically limited in most aircraft to provide precise control during taxiing and low-speed maneuvers without compromising safety. The number indicated, in this case, refers to the typical degree of movement available for nosewheel steering when using the rudder pedals, which enhances maneuverability on the ground.

In many aircraft, the rudder pedals control the nosewheel through a mechanical or hydraulic link, allowing the pilot to steer the aircraft by applying pressure to the pedals. The figure of 7° signifies that the nosewheel can pivot from the centerline of the aircraft to the left or right by this amount when the rudder pedals are fully deflected. This level of authority helps facilitate tighter turns and more effective directional control while on the ground, optimizing the pilot's ability to navigate taxiways and runways safely.

It’s important to note that while larger steering angles could theoretically allow for greater maneuverability, design considerations limit this authority to maintain stability and prevent excessive forces that could lead to loss of control or damage to the aircraft. This context underscores why 7°, chosen as the correct answer, represents a balanced approach to ground steering authority.
