24. Wake Turbulence Avoidance

Question 1

When is wake turbulence the strongest?

Answer 1

Behind large, slow airplanes during take off or landing.

Question 2

When does wake turbulence become and remain a hazard?

Answer 2

When an airplane rotates for takeoff, and remains a hazard until the airplane lands.

Question 3

Wake turbulence strength is determined by:

Answer 3

1. Wing shape
2. Speed
3. Weight of the airplane.

Question 4

Wake turbulence vortices tend to:

Answer 4

Descend about 400-500 feet per minute

and

Level off about 900 feet below the flight path of the generating airplane.

Question 5

You are following behind a large airplane to land on the same runway. You should:

Answer 5

1. Stay above the large airplane’s flight path

2. Touch down beyond where the large aircraft landed.

Question 6

You are landing on a runway where another large airplane is departing. You should:

Answer 6

Watch where it rotates, and land before that point.

Question 7

You are landing on a crossing runway behind a large departing airplane. You should be aware that:

Answer 7

If the large aircraft rotates before the runway intersection, vortices will have been generated and flight under the large airplane’s path should be avoided.

Question 8

If taking off or landing behind a large aircraft, a safe way to avoid wake turbulence is:

Answer 8

Asking the controller to allow at least three minutes prior to departing or landing behind a large airplane.

Question 9

You are landing on the same runway behind a large airplane. You should:

Answer 9

1. Stay above the large airplane’s flight path and note where it touches down.
2. Land beyond that point.

Question 10

While flying under visual conditions, to avoid wake turbulence in flight, you should:

Answer 10

1. Avoid flying behind and below a large aircraft

2. If possible, adjust position laterally, towards the upwind.
