How should the flight controls be positioned while taxiing a tailwheel airplane in a left quartering tailwind?

In a tailwheel airplane, during taxiing in a left quartering tailwind, maintaining control of the aircraft is crucial to prevent it from veering off course. When a quartering tailwind comes from the left, the wind can cause the tail of the airplane to swing towards the right, which could lead to unwanted yaw or loss of control.

To counteract this tendency, the appropriate control position involves lowering the left aileron, which increases the resistance against the wind pushing the tail to the right. This action helps keep the wings level and stabilizes the aircraft directionally. Additionally, positioning the elevator down slightly helps maintain a proper nose attitude, preventing the tail from rising too much and remaining responsive to the wind effects.

Thus, the correct answer emphasizes the necessary control adjustments to manage the airflow and maintain stability while taxiing in these specific wind conditions effectively.
