When taxiing with a quartering tailwind, what should the elevator and upwind aileron be positioned?

When taxiing with a quartering tailwind, the correct approach is to position both the elevator and the upwind aileron down. This configuration helps maintain control of the aircraft by counteracting the effects of the wind on the wings and tail.

The quartering tailwind can lift the upwind wing, potentially leading to an imbalance and causing the aircraft to roll toward that wing. By applying downward pressure on the upwind aileron, you help keep the wing level and ensure that it remains under control.

Setting the elevator down is also crucial because it helps maintain a lower nose attitude, which can reduce the chances of a nose-wheel lift-off that might otherwise result from wind interference. This combination effectively stabilizes the aircraft during taxiing in challenging wind conditions, ensuring that the pilot can handle lateral control effectively while also managing the pitch of the aircraft.
