Their overt objective is European standardisation.
Of course it sounds wonderful, especially with the magic word ("safety") in there
And nothing arouses stronger emotions (among people who haven't got a clue what they are voting on, which is most of them) than aviation safety. You climb into a 737 and you hand your life over to the two blokes up front ... this is powerful stuff.
But the way they are going about it is stupid. One should always try to enhance an existing system, not enhance a few bits while degrading other bits.
And it is a fantastic gravy train.
