There is a missing bit to this conversation. Let's assume that some work is needed to validate a pilot's licence. The if I want to validate ny JAA PPL/IR for FAA/IR i take a simple foreign pilot's exam and a straightforward flight test much like a BFR.
Compare that with EASA's proposals for validating FAA/IR for a EASA/IR.
Edited to add: EASA is utterly disingenuous when using the EU policies as an excuse for its overbearing detail. The weight of detail is EASA's grossly overengineered and gold palted interpretation of the EU policy decisions.
They could be wholly compliant with commission policy by tidying up and SIMPLIFYING JAA regs, what they are doing is making everything more complicated and costly, this isn't about Brussels or Washington it's about Cologne.
