Thanks Dashcam.
This is why I am confused. I have told AFA I have a UK issued licence not in the process of converting it when they asked me to fill out the form, but I have been sent the Cut-e tests to do still. I am gonna do them because its worth a shot, maybe there is a simplified conversion in the pipeline between NAA's eg CAA to IAA as oppose to the usual EASA to FAA. My understanding is currently RYR pilots with an EASA licence cannot renew their medical in the UK as there isn't a process in place for CAA registered AME's to carry out renewals/reval on EASA medical holders, which is why I think there maybe a simpler conversion between NAA's with the CAA in the future, but what do I know!
