1. Ensure that aircraft are vertically separated for a time interval equal to the applicable minimum required before and after the aircraft are estimated to pass.
(See FIG 8-3-3.)

FIG 8-3-3. Reciprocal Courses

2. Vertical separation may be discontinued after one of the following conditions are met:

(a) Both aircraft have reported passing a significant point and the aircraft are separated by at least the applicable minimum required for the same direction longitudinal spacing;
(See FIG 8-3-4.) or

FIG 8-3-4. Vertical Separation

(b) Both aircraft have reported passing ground-based NAVAID's or DME fixes indicating that they have passed each other.
