"The higher your angle-of-attack, the larger your wingtip vortices are, assuming ground effect isn't playing a role (which we'll get to shortly). In general, the three factors that produce large wingtip vortices are: heavy, clean (no flaps), and slow, because you need to fly at a higher angle-of-attack in all … Meer weergeven Induced drag is created as a result of lift. As your wing passes through the air, an area of lower air pressure is formed on the top of the wing. Higher-pressure air below the wing seeks equilibrium with the lower pressure area … Meer weergeven When you fly close to the ground, generally within one wingspan, you'll start to notice ground effect. When you're flying close to the … Meer weergeven Wingtip vortices induce downwash, which changes the relative wind and tilts your lift vector backward. And as your lift vector tilts backward, you generate more induced drag. Meer weergeven Aside from induced drag, wingtip vortices can create a safety hazard as well. As you fly through the air, the vortex you've generated creates a spiraling mass of air. If another … Meer weergeven " - Induced downwash
