2-1-20. WAKE TURBULENCE CAUTIONARY ADVISORIES

1. Issue wake turbulence cautionary advisories including the position, altitude if known, and direction of flight to aircraft operating behind an aircraft that requires wake turbulence separation when:
   • REFERENCE
   • AC 90-23, Aircraft Wake Turbulence, Pilot Responsibility, Para 11
   • FAA Order JO 7110.65, Para 5-5-4, Minima, Subparagraph g
   1. TERMINAL. VFR aircraft not being radar vectored are behind the larger aircraft.
   2. IFR aircraft accept a visual approach or visual separation.
      • REFERENCE
      • FAA Order JO 7110.65, Para 7-4-1 , Visual Approach.
   3. TERMINAL. VFR arriving aircraft that have previously been radar vectored and the vectoring has been discontinued.
2. Issue cautionary information to any aircraft if in your opinion, wake turbulence may have an adverse effect on it. When traffic is known to be a Super aircraft, include the word Super in the description. When traffic is known to be a Heavy aircraft, include the word Heavy in the description.

   NOTE: Wake turbulence is generated when an aircraft produces lift. Because the location of wake turbulence is difficult to determine, the controller is not responsible for anticipating its existence or effect. Aircraft flying through a Super/Heavy aircraft's flight path may have an increased chance of a wake encounter.
