Where do you aviate. Fortunately there are still some airports that mix traffic - I landed behind a DC-10 the other evening.
I think you misunderstood me....Mixed traffic - everywhere I fly pretty much is mixed traffic from lights & to heavies.
The point was not about final approach - but where you have two very different types of aircraft flying the SAME circuit pattern as opposed to different circuits.
i.e. Gloucester - Helo cct at 750, fixed wing at 1000, popham has different microlight & light a/c circuits, brize heavies go round at 1500' but lights go round at 1000' - again completely different size of circuit as well....
thus what I was talking about was a situation where you have a citation flying the same size circuit at the same height as a pa28 - it wont happen - the citation needs more space. As for final - well everybody ends up here eventually (I hope!!!)
Does that clear it up? sorry for any confusion.

ATZ is regulated airspace. With ATC you *must* obtain a clearance to enter it. At AFIS or Radio you will find the UK AIP says you do not need a clearance but must have appraised yourself of the traffic situation to the point that you can ensure the flight is safe. Or some such words to that effect.
Hope this helps.
