    TERMINAL. Authorize simultaneous operations between an aircraft departing on a runway and an aircraft on final approach to another parallel or nonintersecting diverging runway if the departure course diverges immediately by at least 30 degrees from the missed approach course until separation is applied and provided one of the following conditions is met:

    NOTE: When one or both of the takeoff/landing surfaces is a helipad, consider the helicopter takeoff course as the runway centerline and the helipad center as the threshold.

    1. When parallel runway thresholds are even, the runway centerlines are at least 2,500 feet apart. (See FIG 5-8-10 and FIG 5-8-11.)

      FIG 5-8-10 Parallel Thresholds are Even

      FIG 5-8-11 Parallel Thresholds are Even
    2. When parallel runway thresholds are staggered and:
      1. The arriving aircraft is approaching the nearer runway: the centerlines are at least 1,000 feet apart and the landing thresholds are staggered at least 500 feet for each 100 feet less than 2,500 the centerlines are separated. (See FIG 5-8-12 and FIG 5-8-13.)

        FIG 5-8-13 Parallel Thresholds are Staggered
        FIG 5-8-13 Parallel Thresholds are Staggered

        NOTE: In the event of a missed approach by an aircraft requiring wake turbulence separation behind it, apply the procedures in Paragraph 3-9-6, Same Runway Separation and/or Paragraph 3-9-8, Intersecting Runway/Intersecting Flight Path Operations to ensure that the larger aircraft does not overtake or cross in front of an aircraft departing from the adjacent parallel runway.

      2. The arriving aircraft is approaching the farther runway: the runway centerlines separation exceeds 2,500 feet by at least 100 feet for each 500 feet the landing thresholds are staggered. (See FIG 5-8-14.)

    3. When nonintersecting runways diverge by 15 degrees or more and runway edges do not touch. (See FIG 5-8-15.)

    4. When the aircraft on takeoff is a helicopter, hold the helicopter until visual separation is possible or apply the separation criteria in subparas a, b, or c.
