Why would we want facilities to downgrade? Let them stay combined if that's more beneficial. PCT went from an 11 back to a 12 just by getting reclassed from consolidated Tracon to Tracon. CI stayed the same but the parameters changed and everyone there got 6%. Basically for free. This is a good thing.CLT started that roughly 5 years ago. If they’re going to be classed as an up/down, everyone should work every position. If they don’t, then they should be split like other former up/downs. Most likely, CLT would fall to a level 11 tower and separate approach and MIA would be a level 10/11 tower and the approach would be 12.
HCF, JCF, ZUA, and ZSU are all Combined Control Facilities. A blend of enroute/terminal.
SFO is a good example of how the CI is broken. All that traffic is run by one controller. The 4 runways intersect and are in simultaneous use. The position is unable to be split. It’s the busiest local in the world.Don't know about SFO, but at IAH they land/depart on the three parallel east/west runways and push out a lot of departures on 15/33 L and R. Maybe a converging runway CI bump. They were a 12 until a few years ago.
Too bad LAS doesn’t do that. They have 2 locals for their converging runways. There’s got to be a way to split it. But then efficiency takes a hit.SFO is a good example of how the CI is broken.
