Definition
A state of aircraft balance in which the center of gravity is forward enough that the airplane has a persistent tendency to pitch the nose down, requiring the pilot to apply continuous back pressure on the elevator (or set nose-up trim) to maintain level flight.
Plain English
The airplane wants to drop its nose on its own, so the pilot has to keep gently pulling back on the controls to hold the nose where they want it.
Context Anchor
Seen in flight control and trim tab discussions, especially when explaining how trim reduces the force a pilot must hold on the controls.
Derivation
“Nose” means the front of the airplane, and “heavy” means it acts as though that front end wants to drop. The phrase helps because the airplane may not literally have too much weight in the nose; it simply behaves that way in pitch.
Why Pilots Care
It increases control forces, raises stall speed, and can reduce climb performance if left uncorrected.
Intuition Check
Nose-heavy does not always mean the nose is physically overloaded. It means the airplane is tending to pitch nose-down unless the pilot or trim corrects it.
Example Sentence 1
After loading two passengers in the front seats and leaving the baggage compartment empty, the pilot noticed a nose-heavy condition and adjusted the trim for nose-up to relieve the back pressure on the yoke.
Example Sentence 2
In a nose-heavy condition the elevator must be held aft or the trim tab deflected upward to maintain level flight at cruise speed.
