Not sure if this is relevant but these EASA proposals are not just for the EU countries.
The countries which joined JAA but remained non-EU (Switzerland, Norway, Croatia, etc) have signed some kind of agreement to be bound by EASA-generated regulations.
However I agree that this is a weird precedent, for non-AOC operations. These have always run on ICAO principles.
It is all the same stuff as EASA is doing on FCL, however. They are using the fact that (a) ICAO allows each member to retain total sovereignity over its airspace and (b) the EU has the power to force each EU country to file any difference to ICAO that the EU sees fit. It's a very "3rd World" way of doing business, which the civilised world abandoned in the 1950s.
The "established" or "residing" bit is almost incapable of enforcement and certainly not in the context of someone about to fly an approach! Think of a businessman flying a "N" reg with perhaps residences in France or the UK but also in Switzerland, the Isle of Man, Hong Kong or Jersey. He may have multiple businesses or interests in these various states. Who can say where he is "established" or "residing"? To try and attach a defined regulatory impact to people operating in a modern global economy is quite absurd.
It is true that people have a residence for tax purposes and for assessing the proper law for say probate or a divorce, but those assessments tend to be made ex post facto. That is quite different from someone on a particular day of the week trying to work out whether they come within the regulation or not. Many people will fin dit virtually impossible to work out whether they are caught by it or not, but more to the point which hard pressed CAA or police force is going to enquire into all this.
Of course, but how many GB have been used up in these forums wondering about how it might work?
Just because a crap law has been drafted and passed doesn't mean it is completely ineffective. In the UK it would be very unlikely but the EU is quite capable of it. My concern would be insurance, not a ramp check.
