Wake turbulence.

ACS element text (the applicant demonstrates understanding of)

Wake turbulence.

Vortices are generated from the moment an aircraft leaves the ground (until it touches down), since trailing vortices are the byproduct of wing lift. For this reason, a pilot must envision the location of the vortex wake and adjust the flight path accordingly.
