When landing behind a large aircraft, what should a pilot do to avoid wake turbulence?

1. Land as close as possible to the large aircraft

2. Stay above the aircraft's final approach path

3. Use maximum flaps during landing

4. Turn off all lights for visibility

The correct answer is: Stay above the aircraft's final approach path

When landing behind a large aircraft, maintaining a position above the large aircraft's final approach path is essential to avoid wake turbulence. Large aircraft generate significant wake turbulence, primarily from their wings as they pass through the air. This turbulence is particularly strong and can be hazardous to smaller aircraft that are flying in close proximity. By staying above the aircraft's final approach path, a pilot decreases the likelihood of encountering the turbulent air left behind. This vertical separation minimizes the risk of the smaller aircraft being disrupted by the vortices created by the larger aircraft's wings. It's important for pilots to have a clear understanding of wake turbulence patterns and to approach landing in a way that enhances safety. Other options do not offer effective strategies for avoiding wake turbulence. Landing as close as possible to the large aircraft would increase the risk of encountering its wake. Using maximum flaps during landing does not directly address the issue of wake turbulence and might even complicate the landing maneuver. Turning off all lights for visibility is irrelevant to the concerns of wake turbulence and does not contribute to improving safety during landing.
