It's not mine
Anything is possible, of course, as once it has been checked against the methodology (and the girls who do it are sharp cookies) and technically reviewed, I shouldn't see it again. All I can say is that I get questions sent back for a typo which could easily be done by EASA, and each question has a full audit trail of comments, so it is unlikely.
I hear you about regulations, but you have to draw a line somewhere - helicopter pilots are still on JAR OPS, at least until very recently. The trick there is not to be too specific.
Re your last comment - some authorities don't have the facilities for open book - in flight planning, for example, the Jep stuff will be in the question now, rather than using the book. I don't see the problem, but there apparently is one. In this respect, EASA don't seem to be able to enforce rules - instead they leave their interpretation to the local authority, which means we are no better off than under JAA.
The German system allows questions that require a typed in answer that must be correct - a good move in my opinion.
