I’m curious to hear what
@ChasenSFO thinks about both the SFO thing and the SQL thing.
I love SFO, because according to the 7110.65, AIM, all the airport design rules about the parallel runways being closer than 4500 ft, etc, it shouldn’t be able to handle the traffic that it does. It gets away with it through converging simultaneous charted visual approaches that rely on the pilots accepting visual separation with the traffic to the parallel before getting too close, local controller telling you “don’t pass the guy on final for the parallel”, local blasting off departures side by side on 1L/1R basically in formation (but it’s ok because the 7110.65 says you can do it if they’re turning away from each other and diverging by more than X degrees) while two other airliners are on short final in formation for the 28s. It’s awesome, but it only works because the “localisms” and exceptions to rules are letting them get away with making an airport handle twice the amount of traffic it’s technically designed to handle, at least on paper. Really they should have built another parallel runway out in the bay on fill greater than 4500 ft away, but the are wouldn’t allow it so they make do with what they’ve got. Like touching the brakes and coming to a stop at O’Hare if you can’t get a word in on ground, all it takes is for someone to refuse a visual separation or not get the bridges and the airport in sight or for the weather to turn IMC and their traffic capacity basically gets cut in half.
As far as treating 28L and 28R as interchangeable departure runways during west flow, that’s a localism that’s based on them not knowing which arrival runway will have a a bigger hole on final they can slot you in and they decide at the last possible moment. If they just dedicated one runway to arrivals and one to departures it would become more predictable, but by smearing them across both they probably eek out more capacity. If finding out your departure runway at the last possible second is not conducive to 121 ops, it’ll probably take ASAPs and meetings between the airlines and the facility to come up with a better system. But keeping in mind that their localisms are what keeps the airport capacity as high as it is, and airlines benefit from higher capacity and on time departures, I’m a bit suspicious that some of your companies (especially the ones with big SFO bases) aren’t slightly biased to maintain the status quo.
As for SQL, it’s a contract tower. Big-ish airplanes operating off a comparably tiny runway. Close proximity to SFO complicates the class D airspace and where to put all the traffic. The place has a ton of local procedures that aren’t written down anywhere official. Besides the “Diamond shaped waterway” noise abatement departure, they didn’t even used to have official TEC routes. I took a tower tour there ~15 years ago and found the coveted unofficial TEC/preferred IFR routes laminated into the table (they weren’t published in the AF/D yet) and the consensus at the time was there was no way to know them unless you were locally based and had the tribal knowledge. Finally, as far as I know there’s STILL no way to legally depart IFR off runway 30. There’s an obstacle departure procedure off Rwy 12 but Rwy 30 is NA. Therefore they do an unofficial / uncharted hybrid VFR to IFR departure off Rwy 30, that’s given verbally by the controller. The local pilots association charted it with heavy caveats:
You don’t depart IFR. You are VFR until crossing the OAK R-165 on right downwind, and I think you receive your actual IFR clearance from Norcal departure on downwind (those in the know correct me if I’m wrong).
Edit: Hoo boy, after listening to that twin Cessna thing all the way through it’s clear he just punched direct to KBFL into ForeFlight and expected the controllers to tell him what to do. Pretty shocked he didn’t bust the bravo on the way out. Oh well rich people gonna do rich people things, at least he was apologetic.
