Slight off topic, but would someone mind explaining what the whole point of EASA is?
Clearly you haven't been in a taxi anywhere near where the EU operates
£50 for a ride which in the UK would be £20, and you are given a receipt with a smile and without even asking for one. Restaurants are £50/head as a baseline (but very nice). Hotels start at £300/night and go to £1000/night if the city is hosting some EU function. When you reach the establishment, the biggest concentration of people is the queue reclaiming expenses. Quite simple really. It works like a magnet, except that a magnet will occassionally pick up some useful objects, and that magnetism is still not really properly understood, and when they do finally work it out, you will need a PhD in maths and a PhD in physics to be able to understand it.
Are there any specific problems which actually DO need to be addressed, over and above leaving the us with the status quo?
There are many things they could have improved, like simply introducing a more accessible IR (like the FAA one), but without introducing all kinds of other garbage designed to force the USA to sign some silly treaty.
One genuinely good thing EASA has actually done is made certification grandfathered pan-EU. I can't off hand think of anything else useful they have actually
delivered, without introducing a load of other bollox at the same time which made the original thing practically worthless (like Part M).
EASA/Eurocontrol is evidently just a huge ego trip for a load of highly paid people.
