6-2-1. MINIMA ON DIVERGING COURSES

Separate aircraft that will fly courses diverging by 45 degrees or more after departing the same or adjacent airports by use of one of the following minima:

1. When aircraft will fly diverging courses:
   1. Immediately after takeoff - 1 minute until courses diverge. (See FIG 6-2-1.)

      

   2. Within 5 minutes after takeoff- 2 minutes until courses diverge. (See FIG 6-2-2.)

      

   3. Within 13 miles DME/ATD after takeoff - 3 miles until courses diverge. (See FIG 6-2-3.)

      

2. TERMINAL. Between aircraft departing in the same direction from different runways whose centerlines are parallel and separated by at least 3,500 feet, authorize simultaneous takeoffs when the aircraft will fly diverging courses immediately after takeoff. (See FIG 6-2-4.)

   

3. TERMINAL. Between aircraft that will fly diverging courses immediately after takeoff from diverging runways: (See FIG 6-2-5.)
   1. Nonintersecting runways. Authorize simultaneous takeoffs when either of the following conditions exist:
      1. The runways diverge by 30 degrees or more.
      2. The distance between runway centerlines at and beyond the points where takeoffs begin is at least:
         1. 2,000 feet and the runways diverge by 15 to 29 degrees inclusive.
         2. 3,500 feet and the runways diverge by less than 15 degrees.

            

   2. Intersecting runways. Authorize takeoff of a succeeding aircraft when the preceding aircraft has passed the point of runway intersection, and
      1. The runways diverge by 30 degrees or more. (See FIG 6-2-6.)

         

      2. The runways diverge by 15 to 29 degrees inclusive and the preceding aircraft has commenced a turn. (See FIG 6-2-7.)

         

6-2-2. MINIMA ON SAME COURSE

Separate aircraft that will fly the same course when the following aircraft will climb through the altitude assigned to the leading aircraft by using a minimum of 3 minutes until the following aircraft passes through the assigned altitude of the leading aircraft; or 5 miles between DME equipped aircraft; RNAV equipped aircraft using ATD; and between DME and ATD aircraft provided the DME aircraft is either 10,000 feet or below or outside of 10 miles from the DME NAVAID. (See FIG 6-2-8 and FIG 6-2-9.)
