Wingtip Vortices: They’re One of the Costs of Lift

Swirling columns of air slowly trail downward behind an airplane—yours included.

Key Takeaways:

Wingtip vortices, a form of wake turbulence, are invisible, rapidly rotating air created by aircraft generating lift and pose a significant hazard, especially to smaller planes.
They are strongest when an aircraft is heavy, clean, and slow, often occurring during takeoff, climb-out, or pre-landing maneuvers, requiring pilots to be aware of their position in four dimensions (space and time).
Pilots can avoid vortices by adjusting landing/takeoff points relative to preceding aircraft and should remain vigilant even with ATC warnings or when waiving separation.
Training for realistic wake turbulence encounters is challenging, underscoring the importance of understanding and anticipating these phenomena.

When people want to talk about something unpleasant, they often invent nicer-sounding phrases to disguise what’s really going on. “Wake turbulence” is the kind of term that can bring to mind vague, unpleasant imagery. “Wingtip vortices” sound nicer—more refined, perhaps—but actually may be more frightening.

The FAA’s definition in its Pilot’s Handbook of Aeronautical Knowledge (PHAK, FAA-H-8083-25C) doesn’t help much: “The rapidly rotating air that spills over an airplane’s wings during flight. The intensity of the turbulence depends on the airplane’s weight, speed, and configuration. Also referred to as wake turbulence. Vortices from heavy aircraft may be extremely hazardous to small aircraft.”
