The table comparing the FAA IR with the JAA IR, at the start of
this tome, is quite interesting.
If you compare line by line you can see that nearly all of the "Euro extras" are set up as blatent business generation measures. There is not a single item which could be thought of as enhancing safety.
But this isn't just EASA. This excess goes back as many decades as anybody can remember. What EASA has done is produced a huge raft of new regulation, a bit of which is good/sensible and a lot of which is useless/pointless. And a big chunk of it is a finger-up at the USA.
