Definition
The single landing gear wheel located under the forward fuselage of an airplane configured with tricycle landing gear. It supports the front of the aircraft on the ground and is typically steerable for taxiing.
Plain English
The wheel at the front of the airplane, under the nose, that you steer with on the ground.
Context Anchor
Seen in weight-and-balance, landing gear, taxiing, takeoff, landing, and ground-handling discussions.
Derivation
“Nose” is used in aviation to mean the forward part of the airplane, and “wheel” means the round part that rolls on the ground. Together, “nose wheel” means the wheel located under the airplane’s forward end.
Why Pilots Care
Weight carried by the nose wheel directly affects steering authority and the risk of a nose-over during braking or soft-field operations.
Grounding Statement
On the ground, the nose wheel is the front support point that helps keep the airplane level and steerable.
Intuition Check
Do not read “nose wheel” as just any wheel near the front of the airplane. It specifically means the front landing-gear wheel that supports the nose when the airplane is on the ground.
Example Sentence 1
After touching down on the main wheels, she gently lowered the nose wheel onto the runway.
Example Sentence 2
During the preflight the student checked the nose wheel strut for proper extension and tire condition.
