Free PSTAR practice Wake Turbulence

Which response is most correct with respect to wake turbulence?

  1. AWing tip vortices are carried by the ambient wind.
  2. BWing tip vortices have a circular and downward motion.
  3. CWake turbulence exists behind all aeroplanes and helicopters in flight.
  4. DAll of the above are correct.Correct answer

Why this is the answer

All three statements are true (TC AIM-AIR, Wake Turbulence / Vortex Characteristics): wing-tip vortices drift with the ambient wind, rotate with a downward, circular motion, and every aircraft generating lift sheds them — so the most complete answer is 'all of the above.'
