Maximum time at TOGA power on two engines is?

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

Answer: (A)

TOGA thrust is the highest power setting used for takeoff and go-arounds, designed to deliver maximum performance for a short, controlled burst. Because it pushes the engines to their limits, there’s a limit on how long you can sustain that level of heat and stress without risking engine damage. On two engines, the certified limit for staying at TOGA is five minutes. Beyond that, the risk of overheating and exceeding engine temperature limits grows, so you would have to reduce thrust to a level appropriate for continuing the flight. The longer durations listed would exceed the safe operating envelope for sustained TOGA power and aren’t permitted.
