Which wind condition would be most critical when taxiing a nosewheel equipped high wing airplane?

1. Quartering headwind

2. Direct tailwind

3. Quartering tailwind

4. Direct headwind

The correct answer is: Quartering tailwind

When taxiing a nosewheel equipped high wing airplane, a quartering tailwind presents the most critical wind condition. This is primarily because the tailwind component can lift the tail of the aircraft and lead to an unstable situation. With high wing aircraft, the center of gravity is typically located below the wing, which can make them more susceptible to being pushed sideways by wind. When there is a tailwind, especially a quartering one, it can create a tendency for the airplane to weathervane into the wind, potentially resulting in loss of directional control during taxi. The nose of the aircraft may also tend to swing towards the wind, leading to difficulties in maintaining a straight path. This scenario makes it critical for the pilot to be particularly vigilant in monitoring the aircraft’s alignment and speed during taxiing. In contrast, other wind conditions, such as a direct headwind or a quartering headwind, can provide better control and stability, as the aircraft is pushed more evenly and securely onto the ground by the wind.
