d. Wake turbulence

ACS element text (the applicant demonstrates understanding of)

Effects of: d. Wake turbulence

Bottom line

Taking off immediately behind another aircraft, particularly a large and heavy transport airplane, creates the risk of a wake turbulence encounter, and a possible loss of control. Approach the runway above a preceding aircraft’s path when landing behind another aircraft and touch down after the point at which the other aircraft wheels contacted the runway.
