So, you reckon one would initially get the validation, and then have a year to pass the four JAA exams (or otherwise "demonstrate" one's superior knowledge
) and pass the checkride?
If so, that is a lot less hassle than doing the JAA IR right now, out of fear of what might happen.... which quite a lot of people have done over the past year or two.
The current EASA proposals must (obviously, politically) represent the most adverse possible set of options.
