Definition
The transition from a climb or descent to steady flight at a chosen altitude, where the pilot adjusts pitch and power so the aircraft maintains constant altitude and the desired airspeed.
Plain English
Stop climbing or descending and fly straight at the altitude you wanted. You hold the altitude steady and let the speed settle.
Context Anchor
Seen during climbs, descents, instrument approaches, and cruise setup, especially when the airplane reaches an assigned or planned altitude.
Derivation
Level comes from an older word for a tool used to show something is even or horizontal. In flight, the idea is similar: the airplane is no longer moving upward or downward, but is being held at an even altitude.
Why Pilots Care
Proper leveling prevents unwanted airspeed changes and ensures stable flight conditions for cruise.
Intuition Check
Do not read level off as simply making the wings level or making the airplane perfectly flat. Here it means ending a climb or descent and holding altitude.
Example Sentence 1
Approaching 6,000 feet, the pilot began to level off, lowering the nose and reducing power as the airspeed increased to cruise.
Example Sentence 2
The aircraft leveled off briefly at pattern altitude before beginning the final descent.
