I can tell you that 22Gp are on the case, and that a small team has been set up to liase with the CAA and to ease the transition to EASA rules.
The CAA's view of who should staff this is not mine. Fair enough, ten years ago the MOD set the current system up as a 'retention incentive', and the onus on producing the case for military exemptions and liasing with the CAA clearly lay with the MOD at that point, it was their initiative. The current situation is different, Part FCL does not say 'the national Authority may present a case if it feels like it...' it says 'the responsible Authority shall credit military experience...'. To my mind that puts the onus squarely on the belgrano, certainly working with MOD, but not shuffling the whole task off onto them.
