2/19/047110.65Pc. Between aircraft departing in the same directionfrom parallel runways/helicopter takeoff courses.Authorize simultaneous takeoffs if the centerlines/takeoffcourses are separated by at least 2,500feet and courses diverge by 15 degrees or moreimmediately after departure. (See FIG 5−8−7 andFIG 5−8−8.)FIG 5−8−7Parallel Runway DeparturesFIG 5−8−8Parallel Helicopter Course DeparturesNOTE−1. This procedure permits a departing aircraft to bereleased so long as an arriving aircraft is no closer than2 miles from the runway at the time. This separation isdetermined at the time the departing aircraft commencestakeoff roll.2. Consider the effect surface conditions, such as ice,snow, and other precipitation, may have on known aircraftperformance characteristics, and the influence theseconditions may have on the pilot’s ability to commencetakeoff roll in a timely manner.5−8−5. DEPARTURES AND ARRIVALS ONPARALLEL OR NONINTERSECTING DIVERGINGRUNWAYSTERMINAL. Authorize simultaneous operationsbetween an aircraft departing on a runway and anaircraft on final approach to another parallel ornonintersecting diverging runway if the departurecourse diverges immediately by at least 30 degreesfrom the missed approach course until separation isapplied and provided one of the following conditionsare met:NOTE−When one or both of the takeoff/landing surfaces is ahelipad, consider the helicopter takeoff course as therunway centerline and the helipad center as the threshold.a. When parallel runway thresholds are even, therunway centerlines are at least 2,500 feet apart.(See FIG 5−8−9 and FIG 5−8−10.)FIG 5−8−9Parallel Thresholds are Even5−8−4. DEPARTURE AND ARRIVALTERMINAL. Except as provided in para 5−8−5,Departures and Arrivals on Parallel or NonintersectingDiverging Runways, separate a departing aircraftfrom an arriving aircraft on final approach by aminimum of 2 miles if separation will increase to aminimum of 3 miles (5 miles when 40 miles or morefrom the antenna) within 1 minute after takeoff.Radar Departures5−8−3
