Section 3. Initial Separation of Departing and Arriving Aircraft

6-3-1. SEPARATION MINIMA

a. Separate a departing aircraft from an arriving aircraft making an instrument approach to the same airport by using one of the following minima until vertical or lateral separation is achieved:

b. TERMINAL. When takeoff direction differs by at least 45 degrees from the reciprocal of the final approach course, the departing aircraft takes off before the arriving aircraft leaves a fix inbound not less than 4 miles from the airport.

c. TERMINAL. When takeoff direction is other than in subpara a, the departing aircraft takes off so that it is established on a course diverging by at least 45 degrees from the reciprocal of the final approach course before the arriving aircraft leaves a fix 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 must be applied.

e. When takeoff direction differs by at least 45 degrees 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 subpara d, the departing aircraft takes off so that it is established on a course diverging by at least 45 degrees 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.)
