Wake Turbulence

No pilot would willingly fly through a tornado. And yet some pilots fail to avoid an equally powerful force. Wake turbulence vortices can reach velocities in excess of 200 mph (300 feet per second) and can far exceed the control authority or structural strength of any light general aviation aircraft in their path. How much do you remember about wake turbulence generation and avoidance? Take this quiz to find out!

1. Wake turbulence is fundamentally a result of ____.

2. Viewed from behind the generating aircraft, the left wingtip vortex rotates ____ and the right wingtip vortex rotates ____.

3. As a rule of thumb, a heavy aircraft with gear and flaps ____ and a ____ airspeed generates the strongest wake turbulence.

4. When on approach to land behind a large aircraft, you should fly ____ the preceding aircraft's flight path and land ____ its touchdown point.

5. For a small aircraft taking off from an intersection on the same runway behind a large aircraft, an air traffic controller must provide a ____-minute delay for wake turbulence.

6. The separation standard for a small aircraft landing behind a heavy jet, such as a Boeing 777, is ____ miles.

7. Calm winds reduce your chance of a wake turbulence encounter.

8. Pilots flying small aircraft should be concerned about the wake turbulence produced by other small aircraft.

9. The ____ has the ultimate responsibility for ensuring appropriate separation and positioning to avoid wake turbulence created by other aircraft.

10. A pilot who suspects that wake turbulence is affecting his or her aircraft on final approach should ____.
