First congrats to the forum for getting to a dozen or so posts w/o someone pitching in with a brexit rant (from either side of the fence). It would be nice to believe this could stay a grown-up discussion.
Two points
First, as I understand it (and I've done my homework to a degree). The vast majority of EU legislation and regulation (some 22000 items or more) is just going to be cut'n'paste straight into UK law (and so is EU case study, to assist in the legal interpretation of law). So the vast burden of all this is going to fall on a bunch of technocrats armed with little more than Microsoft Word and Adobe. Whatever happens after that to this "mountain of law" will depend on UK political culture in the next few dozen decades, but clearly, nothing much is happening "overnight" (where "overnight" equals most of our lifetimes). I've seen nothing to suggest that aviation would be a special case, and common sense - specifically the need to keep flying - suggests it would a strong contender for the default (change nothing) option.
Which brings me neatly to my second point...aviation has long been identified as the tip of the spear in this particular UK "adventure". Good ol Mr Ryanair has had a few rants of the subject. Whatever happens is gonna happen to aviation first so in many ways it will be the bellweather for events to come. That's why it is an interesting, pertinent topic and one hopes for an educated and fruitful discussion.
Exciting isn't it
