inbound not less than 4 miles from the airport.
d. TERMINAL. When the absence of an appropriate
fix precludes the application of subparas b or c and
at airports where approach control service is not
provided, the separation in subparas e or f shall be
applied.
e. When takeoff direction differs by at least
45degrees from the reciprocal of the final approach
course, the departing aircraft takes off 3 minutes
before the arriving aircraft is estimated at the airport.
(See FIG 6-3-1.)

f. When takeoff direction is other than in
subparad, the departing aircraft takes off so that it is
established on a course diverging by at least
45degrees from the reciprocal of the final approach
course 5 minutes before the arriving aircraft is
estimated at the airport or before it starts procedure
turn. (See FIG 6-3-2 and FIG 6-3-3.)

6-4-1. APPLICATION
Separate aircraft longitudinally by requiring them to
do one of the following, as appropriate:
a. Depart at a specified time.
b. Arrive at a fix at a specified time.
PHRASEOLOGYCROSS
(fix) AT OR BEFORE (time).
CROSS (fix) AT OR AFTER (time).

6-4-2. MINIMA ON SAME, CONVERGING,
OR CROSSING COURSES
Separate aircraft on the same, converging, or crossing
courses by an interval expressed in time or distance,
using the following minima:
a. When the leading aircraft maintains a speed at
least 44 knots faster than the following aircraft -
5miles 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, or 3 minutes between other aircraft
if, in either case, one of the following conditions is
met:
1. A departing aircraft follows a preceding
aircraft which has taken off from the same or adjacent
airport. (See FIG 6-4-1.)

Minima on Same Course
44 Knots or More Separation
2. A departing aircraft follows a preceding
enroute aircraft which has reported over a fix serving
the departure airport. (See FIG 6-4-2.)

b. When the leading aircraft maintains a speed at
least 22 knots faster than the following aircraft -

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; or 5 minutes between other aircraft
if, in either case, one of the following conditions
exists:
1. A departing aircraft follows a preceding
aircraft which has taken off from the same or an
adjacent airport. (See FIG 6-4-4.)

c. When an aircraft is climbing or descending
through the altitude of another aircraft:
1. 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- 10 miles, if the descending aircraft
is leading or the climbing aircraft is following.
