In JO 7110.65X, section 3-9-6(j) says in reference to the 3 minute rule:
j. Separate an aircraft behind another aircraft that has departed or made a low/missed approach when utilizing opposite direction takeoffs or landings on the same or parallel runways separated by less than 2,500 feet by the following minima:
Heavy, large, or small behind super − 4 minutes.
Heavy, large, or small behind heavy − 3 minutes
Do you think this applies to an aircraft in the pattern making approaches to the runway in use after a heavy departs opposite direction?
