Definition
The highest engine power setting the manufacturer permits for takeoff, as specified in the Pilot's Operating Handbook (POH) or Airplane Flight Manual (AFM). It represents the upper limit of power the engine is certified to produce for the takeoff phase, and is the power setting applied during a go-around when full performance is needed.
Plain English
The most power the manufacturer allows you to use for takeoff. In a go-around, you push the throttle up to this setting to climb away safely.
Context Anchor
Seen in go-around procedures, when the pilot adds power to stop the descent and climb away from the runway.
Why Pilots Care
Prevents engine damage or failure during high-power demands such as a go-around while still providing the performance needed for a safe climb.
Intuition Check
Maximum allowable takeoff power does not mean any power the engine can physically produce. It means the highest power the pilot is permitted to use under the airplane's approved limits.
Example Sentence 1
When the instructor called the go-around, the pilot smoothly advanced the throttle to maximum allowable takeoff power and pitched for a positive climb.
Example Sentence 2
Before takeoff the pilot confirmed that the engine could produce maximum allowable takeoff power at the current density altitude.
