2/19/047110.65PREFERENCE−FAAO 7110.65, Wake Turbulence Separation for Intersection Departures,Para 3−9−7.3−9−7. WAKE TURBULENCE SEPARATION FORINTERSECTION DEPARTURESa. Apply the following wake turbulence criteriafor intersection departures:1. Separate a small aircraft taking off from anintersection on the same runway (same or oppositedirection takeoff) behind a preceding departing largeaircraft by ensuring that the small aircraft does notstart takeoff roll until at least 3 minutes after the largeaircraft has taken off.2. Separate any aircraft taking off from anintersection on the same runway (same or oppositedirection takeoff), parallel runways separated by lessthan 2,500 feet, and parallel runways separated byless than 2,500 feet with runway thresholds offset by500 feet or more, by ensuring that the aircraft does notstart takeoff roll until at least 3 minutes after a heavyaircraft/B757 has taken off.NOTE−Parallel runways separated by less than 2,500 feet withrunway thresholds offset by less than 500 feet shall applypara 3−9−6, Same Runway Separation, subpara f.3. Separate a small aircraft weighing 12,500 lbs.or less taking off from an intersection on the samerunway (same or opposite direction takeoff) behind apreceding small aircraft weighing more than12,500 lbs. by ensuring the following small aircraftdoes not start takeoff roll until at least 3 minutes afterthe preceding aircraft has taken off.4. Inform an aircraft when it is necessary to holdin order to provide the required 3−minute interval.PHRASEOLOGY−HOLD FOR WAKE TURBULENCE.NOTE−Aircraft conducting touch-and-go and stop-and-gooperations are considered to be departing from anintersection.REFERENCE−FAAO 7110.65, Touch−and−Go or Stop−and−Go or Low Approach,Para 3−8−2.b. The 3−minute interval is not required when:1. A pilot has initiated a request to deviate fromthat interval unless the preceding departing aircraft isa heavy aircraft/B757.NOTE−A request for takeoff does not initiate a waiver request; therequest for takeoff must be accomplished by a request todeviate from the 3−minute interval.2. USA NOT APPLICABLE. The intersectionis 500 feet or less from the departure point of thepreceding aircraft and both aircraft are taking off inthe same direction.3. Successive touch−and−go and stop−and−gooperations are conducted with a small aircraftfollowing another small aircraft weighing more than12,500 lbs. or a large aircraft in the pattern, or a smallaircraft weighing more than 12,500 lbs. or a largeaircraft departing the same runway, provided the pilotof the small aircraft is maintaining visual separation/spacing behind the preceding large aircraft. Issue awake turbulence cautionary advisory and the positionof the large aircraft.EXAMPLE−“Caution wake turbulence, DC−9 on base leg.”4. Successive touch-and-go and stop-and-gooperations are conducted with any aircraft followinga heavy aircraft/B757 in the pattern, or heavyaircraft/B757 departing the same runway, providedthe pilot of the aircraft is maintaining visualseparation/spacing behind the preceding heavyaircraft/B757. Issue a wake turbulence cautionaryadvisory and the position of the heavy aircraft/B757.EXAMPLE−“Caution wake turbulence, heavy Lockheed C5Adeparting runway two three.”5. If action is initiated to reduce the separationbetween successive touch-and-go or stop-and-gooperations, apply 3 minutes separation.c. When applying the provision of subpara b:1. Issue a wake turbulence advisory beforeclearing the aircraft for takeoff.2. Do not clear the intersection departure for animmediate takeoff.3. Issue a clearance to permit the trailing aircraftto deviate from course enough to avoid the flight pathof the preceding large departure when applyingsubpara b1 or b2.4. Separation requirements in accordance withpara 3−9−6, Same Runway Separation, must alsoapply.REFERENCE−FAAO 7110.65, Same Runway Separation, Para 3−9−6.Departure Procedures and Separation3−9−5
