6-3-1 Separation Minima

 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:

 a. 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.
 b. TERMINAL: When takeoff direction is other than in subparagraph 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.
 c. TERMINAL: When the absence of an appropriate fix precludes the application of subparagraphs a or b, and at airports where approach control service is not provided - The separation in subparagraphs d or e shall be applied.
 d. 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 Figure 6-3-1)
 

 e. When takeoff direction is other than in subparagraph 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 Figure 6-3-2 and Figure 6-3-3)
