Definition
A ground-handling system that allows the pilot to turn the airplane during taxi by steering the nosewheel directly through the rudder pedals. On most light airplanes the rudder pedals are mechanically linked to the nose gear, so pressing the left or right pedal turns the nosewheel in that direction. On larger aircraft a separate hand-operated tiller may also be used for tighter turns.
Plain English
It's how you steer the plane on the ground. You push the pedals with your feet to turn the front wheel left or right, the same way a steering wheel turns a car.
Context Anchor
You encounter nosewheel steering during taxi, especially when using the rudder pedals to keep the airplane moving along the taxiway centerline.
Derivation
Nosewheel combines nose (front of the aircraft) with wheel. Steering derives from the Old English steoran, to guide or direct a vessel. Together the words describe the act of guiding the airplane by turning its forward wheel.
Why Pilots Care
Precise nosewheel steering prevents runway and taxiway excursions and reduces reliance on brakes or differential power during normal taxiing.
Intuition Check
Nosewheel steering does not mean the airplane is steering through the air. It refers to steering on the ground by turning the front wheel.
Example Sentence 1
After engine start, the pilot used nosewheel steering to taxi the airplane onto the centerline of the taxiway.
Example Sentence 2
In a strong crosswind the pilot used a combination of nosewheel steering and aileron deflection to keep the airplane aligned with the taxiway centerline.
