WebSep 18, 2024 · 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 above, resulting in a vortex flow from the bottom of the wing to the top. Boldmethod.
