Begs the question if such a tight environment can sustain a mixed operation of heavies and medium and smaller. Some times it seems like the increase of pax uplift of the biggies is annihilated with the necessary separation for medium and lighter ac. Avid aviators out of DXB know what i am pointing at. The painful wait after a super departure when some 737 or 320 are due ....
En route slop might mitigate the problem, but if 2nm l/r are a problem in TMAs, then the bigwakeshakers almost inhibit parallel lightweight ops.
