What thrust procedure is recommended for takeoff under the described wind condition?

• A. Apply maximum idle/taxi thrust before brakes released, then set TOGA at 60 KIAS
• B. Apply TOGA thrust immediately after brakes release
• C. Set CLB thrust and hold until 60 KIAS
• D. Maintain idle thrust throughout the takeoff roll

Answer: (A)

In this wind condition, a controlled, staged transition to takeoff thrust helps maintain directional and pitch control during the critical roll. Starting from idle/taxi thrust and delaying full takeoff thrust until you reach a modest speed keeps engine response predictable and reduces the chance of a sudden thrust surge fighting gusts or crosswinds at very low airspeeds. Once you’re at 60 KIAS, advancing to TOGA provides the needed thrust for a proper takeoff with a smoother, more controllable transition to climb. Jumping straight to takeoff thrust right after brakes release can create an abrupt change in thrust input when the aeroplane is still light and more susceptible to gust-induced movement. Holding CLB thrust instead of full takeoff thrust would not meet the required performance for a normal takeoff, and staying at idle throughout would fail to achieve the necessary acceleration.
