Definition
The single landing gear wheel located under the nose of an airplane that has a tricycle landing gear configuration. It supports the front of the airplane on the ground and is typically steerable, allowing the pilot to direct the airplane during taxi.
Plain English
The wheel at the front of the airplane, under the nose, on airplanes whose main wheels sit behind the cockpit rather than at the tail.
Context Anchor
You will see this term in discussions of taxiing, takeoff, landing, and how an airplane sits and moves on the ground.
Derivation
Nose comes from the Old English word for the projecting front of the face; wheel from the Old English term for a circular rolling object. Combined, the term points directly to the wheel positioned at the aircraft's forward end, helping distinguish it from tailwheel configurations.
Why Pilots Care
Affects ground steering, weight distribution during takeoff and landing, and the choice of aircraft handling techniques in normal and crosswind conditions.
Intuition Check
Do not think of the nose-wheel as just a simple support wheel. On many airplanes, it is also part of how the pilot steers while moving on the ground.
Example Sentence 1
After touchdown, the pilot held the nose-wheel off the runway until the airspeed dropped, then let it settle gently.
Example Sentence 2
After landing, the pilot kept the nose-wheel off the runway as long as possible to reduce wear on the tire.
