What can engaging Nosewheel Steering (NWS) at high speeds lead to?

Engaging Nosewheel Steering (NWS) at high speeds can lead to directional control problems due to the mechanical limitations and behavior of the aircraft. At higher speeds, the forces acting on the aircraft increase, making it more sensitive to inputs from the nosewheel steering. If the nosewheel is turned too sharply or too quickly while the aircraft is moving at higher speeds, it can result in a loss of control, causing the aircraft to skid or veer off the desired trajectory.

NWS is designed to aid in low-speed ground maneuvers, and at higher speeds, the steering effectiveness diminishes while the potential for oversteering and skidding increases. Therefore, it is crucial for pilots to carefully evaluate the appropriate use of nosewheel steering during taxiing, taking into account the speed of the taxi to maintain safe directional control.
