Wake Turbulence Avoidance Flashcards
What is wake turbulence?
Pair of counter rotating vortices caused by the wing tips of an aircraft generating lift
What is the path of vortices?
Behind the aircraft sinking about 400-500 feet per minute, and level off about 900 feet below the flight path
Where do you takeoff after a large aircraft to avoid wake turbulence?
Watch where it rotates, and takeoff before that point. Climb over the airplanes climb path until you can turn (into the wind) away from the path of the generating airplane.
Where do you land after a large aircraft to avoid wake turbulence?
Stay above its flight path and land beyond where it touches down.
Where do you land on a parallel runway with a large aircraft?
Beyond their point of touchdown and above its flight path.
Where do you land behind a large aircraft departing?
Note where it rotates and land before that point.
Where do you land on an intersecting runway with a departing aircraft?
If it rotates after the intersection, you are safe. If it rotates before the intersection, land before the intersection. If you can’t? Go around.
How many minutes should you allow before taking off or landing behind a large airplane?
3 minutes if possible
If you are enroute VFR flight rules, what should you avoid?
Below and behind large aircraft flight paths, and if possible adjust the flight path upwind
