Definition#
Wake turbulence is the disturbed air behind an aircraft caused by rotating wingtip vortices. These vortices are strongest behind heavy, clean, slow aircraft and descend and spread laterally after generation.
Why It Matters Operationally#
ATC enforces minimum separation (time or distance) behind heavy/super aircraft categories to prevent wake encounters. Wake turbulence can cause uncommanded roll and altitude deviations, particularly hazardous near the ground.
