Definition
A flight condition in which the airplane is held at the same altitude throughout a maneuver, with no climb or descent, by maintaining a level pitch attitude and adjusting power and trim as needed.
Plain English
Flying so that your height above the ground stays the same the whole time — you don't go up or down.
Context Anchor
Used in ground reference maneuvers such as the rectangular course, where the pilot practices flying a planned path over the ground while holding altitude steady.
Derivation
Constant comes from a Latin idea meaning “standing firm” or “remaining unchanged.” Altitude comes from a Latin word meaning “height.” Together, the phrase points to a height that stays unchanged during the maneuver.
Why Pilots Care
Maintains consistent visual references, safe terrain clearance, and proper pattern altitude for the entire maneuver.
Grounding Statement
In a rectangular course, the airplane should go around the field while staying at the chosen altitude instead of slowly drifting higher or lower.
Intuition Check
Constant altitude does not mean constant airspeed, constant power, or the same view out the window. It means the airplane’s altitude stays the same while other things may change.
Example Sentence 1
The instructor asked the student to fly the rectangular course at a constant altitude of 1,000 feet AGL.
Example Sentence 2
During rectangular course practice, the instructor emphasized constant altitude to keep the entire pattern at the published traffic height.
