FAA Ground School Practice Test

Which aileron position is most effective when taxiing in strong quartering and headwinds?

1. Aileron up on the side from which the wind is blowing

2. Aileron's down on the side from which the wind is blowing

3. Both ailerons neutral

4. Both ailerons down

The correct answer is: Aileron up on the side from which the wind is blowing

When taxiing in strong quartering and headwinds, adjusting the ailerons to a position where the aileron is up on the side from which the wind is blowing is effective for maintaining control of the aircraft. By having the aileron on the windward side (the side facing the wind) positioned upward, it allows the airflow over the wing to create a more stable situation by reducing the tendency of the wing to rise on that side. This configuration helps to keep the wing down and prevents the aircraft from being pushed sideways by the wind, which could lead to a loss of control. Positioning the ailerons in this way is a common technique used by pilots during taxi operations in windy conditions, as it enhances directional stability and assists in maintaining the intended flight path. When the aircraft is flown into a strong wind, choosing the proper aileron position is crucial to counteracting the wind's force and ensuring smooth operation on the ground.
