Definition
A condition in which the airplane's center of gravity is located forward of the ideal range, causing the nose to pitch downward and requiring more elevator back-pressure or up-trim to hold level flight.
Plain English
The airplane wants to drop its nose because there is too much weight toward the front, so the pilot must pull back or trim up to keep it flying level.
Context Anchor
Seen in longitudinal stability, loading, and trim discussions, especially when weight is placed forward or the center of gravity is near its forward limit.
Derivation
The term combines “nose,” meaning the front of the aircraft, with “heavy,” used here in the sense of a strong tendency or control feel. It does not mean the nose itself is unusually heavy; it means the airplane is balanced so the front wants to go down.
Why Pilots Care
It increases the back pressure needed on the controls, reduces the ability to flare properly on landing, and can make stall recovery more abrupt.
Grounding Statement
Picture the airplane as balanced on a point: if too much weight is forward of that point, the nose side wants to tip down.
Intuition Check
Nose-heavy does not mean the nose structure weighs too much. It means the airplane’s balance makes the nose tend to drop.
Example Sentence 1
With both pilots up front and no baggage in the rear, the airplane was nose-heavy and needed noticeable up-trim to hold cruise.
Example Sentence 2
The pilot added nose-up trim to relieve the heavy nose-down force caused by the forward center of gravity.
