APR power (one engine) is limited to how many minutes?

• A. 10 Minutes
• B. 5 Minutes
• C. 15 Minutes
• D. 20 Minutes

Answer: (A)

APR power on the remaining engine is a short-duration, high-thrust setting used after an engine out to keep you controllable and able to reach a safe landing. It is limited to ten minutes to protect the engine and related systems from overheating and excessive stress while you manage the approach and landing with one engine in APR. This time window gives you enough performance to complete the maneuver safely without pushing components beyond their certified limits. Deviating beyond that limit could push turbine temperatures and mechanical loads past safe margins, so the ten-minute cap is the reason it’s the correct choice.
