The CAA are stating they are proud to be early adopters. Most other NAAs are delaying to the maximum.
Consequently they are bound to screw up legislation as they haven't had time to fully digest the implications
Look, for example, about the new requirement to email the CAA naming the examiner and not being permitted to take a skills test without confirmation from the CAA. This one is dated one month AFTER the 17th Sept changeover.
They are looking to see how to implement this, but shirley, they would have been better waiting to go through the requirements to see how the French dealt with it.
