then we can do away with most ground based ATC

I think the busier airports will say no to that.

Even with all traffic info on board, we still won’t be able to all self organise and expect the airport’s runway to be optimised without ATC. It would be radio chaos. With someone controlling, it means more fees collected per hour to them and less wasted flight time and fuel spent for us.

That said I think they should still allow uncontrolled movements with restrictions when ATC isn’t around, and not do a Cranfield.

80 000 runway movements, 6000 IAPs and 10 000 ‘known’ transits might have something to do with it

matspart3, whilst rolling his eyes, hasn't read my question properly either (I won't roll my eyes in return...). My question has nothing to do with Gloucester. It was "why do we need (AT)Control outside controlled airspace". Do members of the Forum not think that air traffic control should only be within controlled airspace? Surely the two go hand-in-glove? (Note the two 'control' words, not difficult) Yet in the UK we have this disconcerting situation with aerodromes with such high movements without any form of CAS protection, just a Mickey Mouse Rule 11 ATZ where you only need permission, and not even a 'clearance', yet equipped with 'air traffic control', mandated or otherwise. Is there no-one else here that thinks that such lack of protection is somewhat irresponsible? I'm sure that matspart3 has been frustrated on occasions whilst attempting to provide SRAs outside CAS. EASA in its infinite wisdom has apparently somewhere (I can't recall where right now) announced that in the near future (2020?) radar vectors will not be permitted outside controlled airspace (except in an emergency). That's the thin end of the wedge which will put the cat amongst the pigeons.

Of course.

Bring on a little more Class D for Gloucester that looks a bit like a MATZ and surround that with a much larger bit of Class E that joins that with the ATS route system.

EASA’s ruling makes sense.

IMHO the sooner we sort out Skyecho etc the better. Maybe then we can do away with most ground based ATC

Yep, I'm game....

Was planning to fly to Gloster (sorry, Gloucestershire) today, called in the morning for PPR and was told "another controller ill so airfield closed all day to visitors".

[Talkdownman]

Found the reference, thanks to Gonzo:

Part-ATS ATS.TR.200 and associated definitions.

Basically, Air Traffic Control service is only available inside CAS.

ATC at Aerodrome = CAS.

No ATC service outside of CAS, only ‘ICAO’ FIS (BS/TS, not DS).

No vectoring outside of CAS unless in an emergency or for immediate safety reasons. Vectoring on to instrument approach procedure is not considered as such.

Lots of comments in the CRD on this, but EASA basically say the UK has got to 2025 to get their poop in a pile on this, and EASA will facilitate consultation workshops in order to assist transition.

Estimated 59 new CTRs (civ and mil) in UK, plus all the extra CAS needed to join them up to airways, assuming some form of vectoring/ATC is required throughout flights

Control only within controlled airspace makes sense to me, then we will all know exactly where we stand. Maybe when Gloucester gets enough ATCOs it ought to also get itself some CAS to protect its large number of movements.

Why do we need ATC at all then? I mean, either it's needed or it isn't at any particular time and place.

Why do we need (AT)Control outside controlled airspace...

Apologies TDMan. I was answering Lobsby's original question not your supplemental. Sorry.

[flybymike]

Is there any statistical data to show how many accidents/incidents/injuries/ fatalities etc have been directly caused by a lack of CAS at ATC aerodromes with an ATZ only?

[James Chan]

I have over the years encountered several incidents of my own, caused by pilots cherry picking instructions from ATC as well as blocking the approach path.

Well, at least we all know why they introduced PPR now...

[bilko2]

It seems to me that with the coming of mass market autonomous flying vehicles (and they are coming, not this year but soon) the old ways won't cut it. Control will have to be some sort of decentralised algorithm based system, maybe supervised by a few humans (to start with anyway).

Repeating back instructions on 1940s tech VHF radios will not be good enough. Seems a bit antiquated now.

modern compared to Morse on HF and Aldis ..

[I'd previously here suggested a preference for renaming Staverton as Cheltenham Gustav Holst, to emulate but trump Liverpool John Lennon ]
