  • 5-8-3. SUCCESSIVE OR SIMULTANEOUS DEPARTURES

    TERMINAL

    Separate aircraft departing from the same airport/heliport or adjacent airports/heliports in accordance with the following minima provided radar identification with the aircraft will be established within 1 mile of the takeoff runway end/helipad and courses will diverge by 15 degrees or more.

    • NOTE:
    • 1. FAA Order 8260.46, Departure Procedure (DP) Program, and FAA Order 8260.3, United States Standard for Terminal Instrument Procedures (TERPS), Volume 4, establishes guidelines for IFR departure turning procedures which assumes a climb to 400 feet above the departure end of runway (DER) elevation before a turn is commenced. TERPS criteria ensures obstacle clearance with a climb gradient of 200 feet per nautical mile from the DER. “Immediately after departure” is considered to be any turn that provides at least 15 degrees of divergence that commences no later than 2 miles from the DER.
    • 2. Consider known aircraft performance characteristics when applying initial separation to successive departing aircraft.
    • 3. When one or both of the departure surfaces is a helipad, use the takeoff course of the helicopter as a reference, comparable to the centerline of a runway and the helipad center as the threshold.
    1. Between aircraft departing the same runway/ helipad or parallel runways/helicopter takeoff courses separated by less than 2,500 feet- 1 mile if courses diverge by 15 degrees or more immediately after departure or 10 degrees or more when both aircraft are departing the same runway and both are flying an RNAV SID. (See FIG 5-8-1, FIG 5-8-2, and FIG 5-8-3.)

      NOTE: RNAV SIDs specific to this paragraph are those SIDs constructed with a specific lateral path that begins at the DER.

      NOTE: This procedure does not apply when wake turbulence separation is required.

    2. Between aircraft departing from diverging runways:
      1. Nonintersecting runways. Authorize simultaneous takeoffs if runways diverge by 15 degrees or more. (See FIG 5-8-4.)

        FIG 5-8-4 Nonintersecting Runway Departures
      2. Intersecting runways and/or helicopter takeoff courses which diverge by 15 degrees or more. Authorize takeoff of a succeeding aircraft when the preceding aircraft has passed the point of runway and/or takeoff course intersection. When applicable, apply the procedure in para 3-9-5, Anticipating Separation. (See FIG 5-8-5 and FIG 5-8-6.)

    3. Between aircraft departing in the same direction from parallel runways/helicopter takeoff courses. Authorize simultaneous takeoffs if the centerlines/takeoff courses are separated by at least 2,500 feet and courses diverge by 15 degrees or more immediately after departure or 10 degrees or more when both aircraft are flying an RNAV SID. (See FIG 5-8-7 and FIG 5-8-8.)

      NOTE: RNAV SIDs specific to this paragraph are those SIDs constructed with a specific lateral path that begins at the DER.
