Section 2. Initial Separation of Successive
Departing Aircraft
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:
NOTE-
1. Consider known aircraft performance characteristics
when applying initial separation to successive departing
aircraft.
2. 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.
a. When aircraft will fly diverging courses:
1. Immediately after takeoff - 1 minute until
courses diverge. (See FIG 6-2-1.)
FIG 6-2-1
Minima on Diverging Courses
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.)

Minima on Diverging Courses
b. 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.)
FIG 6-2-4
Minima on Diverging Courses
c. 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:
(a) The runways diverge by 30 degrees or
more.
(b) 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.

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