Engine thrust between which range is prohibited with tailwinds greater than 10kts or crosswinds greater than 25kts?

Engine thrust between which range is prohibited with tailwinds greater than 10kts or crosswinds greater than 25kts?

• A. 45-55%
• B. 10kts
• C. 25kts
• D. 60kts

Answer: (A)

In gusty wind conditions, especially with a tailwind over 10 knots or a crosswind over 25 knots, your engine-thrust setting needs to provide clear, stable control margins. The mid-thrust range around 45–55% sits in a narrow envelope where small gusts can cause noticeable fluctuations in thrust and airspeed, making it harder to maintain a steady climb or safe go-around. That zone also often offers less engine response headroom to counter gust-induced changes, which can lead to control difficulties or an inability to achieve the required performance quickly enough. To keep handling robust under those wind conditions, that mid-thrust band is avoided, so you either set thrust lower than 45% for smoother, more controllable response or higher than 55% to ensure adequate acceleration and margins.
