Definition
The highest power setting an engine is approved to sustain indefinitely without time limit, as established by the manufacturer and reflected in the aircraft's operating limitations. It is lower than takeoff power, which is typically time-limited to a few minutes.
Plain English
The strongest setting the engine is allowed to run at for as long as you want without damaging it. Takeoff power is stronger but can only be used briefly; this is the highest setting that's safe to leave on continuously.
Context Anchor
Seen in aircraft operating limitations, engine specifications, and performance discussions for light-sport aircraft.
Derivation
Continuous' comes from Latin continuus, meaning 'uninterrupted' or 'unbroken.' The term literally describes the maximum power the engine can produce on an unbroken, time-unlimited basis -- distinguishing it from short-duration ratings like takeoff power.
Why Pilots Care
Exceeding this limit for long periods risks engine damage or failure during extended flight.
Intuition Check
Do not assume “maximum” means any power the engine can briefly produce. Here it means the highest power that is approved for continuous use.
Example Sentence 1
After reaching a safe altitude, the pilot reduced from takeoff power to maximum continuous power for the climb.
Example Sentence 2
Engine data plates list maximum continuous power as 100 horsepower at 5,800 RPM for unlimited use.
