What is the normal takeoff and max power limit for two engines?

• A. 5 min
• B. 3 min
• C. 10 min
• D. 7 min

Answer: (A)

Takeoff power is a high-thrust setting used only for a short duration to get the airplane started and safely airborne. When both engines are operating, the engine limits specify a time cap for using that higher power—you don’t hold it forever, you limit it to protect the engines from overheating and excessive wear.

For a two-engine airplane, that takeoff-power window is five minutes. After that window, you must reduce power to the maximum continuous (or climb) setting published for safe, longer-term operation. This ensures you have a safe margin while still achieving the necessary performance for takeoff and initial climb.

The other time options aren’t the standard published limit for two-engine takeoff power, which is why five minutes is the best answer.
