Aircraft on reciprocal tracks may be cleared toclimb or descend to or through the altitude(s) occupiedby another aircraft provided that:(a) An ADS−A position report on at least one ofthe aircraft has been received beyond the passing point,and(b) The aircraft have passed each other by theapplicable separation minimum.NOTE−Ocean21 has been designed to check for the abovecriteria prior to allowing the minima to be provided.3. When an ADS−A periodic or waypoint changeevent report is overdue by 3 minutes, the controller shalltake action to obtain an ADS−A report.4.
