During taxi in a quartering tailwind, what control surface position is warranted?

• A. Ailerons into the wind
• B. Ailerons neutral
• C. Ailerons away from the wind
• D. Ailerons deflected fully

Answer: (C)

When taxiing in a quartering tailwind, it is necessary to position the ailerons away from the wind. This control surface position helps to counteract the tendency of the aircraft to be pushed by the wind on the tail, which can cause the upwind wing to rise and the downwind wing to drop. By deflecting the ailerons away from the wind, the pilot can create a lift force on the downwind wing, maintaining a level attitude and enhancing overall directional control. This technique is crucial for maintaining stability and ensuring that the aircraft does not inadvertently tip over or experience difficulty controlling its lateral motion, especially in gusty wind conditions. Understanding the aerodynamics involved in this situation allows pilots to make better decisions regarding control surface positions during taxi operations.
