I don't think we should panic, but we should be investigating all our options and be prepared. I have just looked out my CAA license cover ready for the replacement license which be issued (I believe).to cover all those who are resident or employed in the U.K. whose EASA license was issued by the CAA. The CAA are not noted for their alacrity in reacting to changing circumstances. Many people, who meet the requirements, have already licenses issued by the state in which they are working. But I believe that by March next year something will be in place, the U.K. aviation industry is not going to stop. I haven't worked in Europe for a number of years so I am not sure if going to another EASA state for a license will need some kind of residency or employer requirement, but I suspect that it might. Along with many engineers I have a foreign (non EASA) license, and shortly may have another. Will be interesting if they will be accepted by EASA land airworthiness authorities for validation
