Yes you can align with EASA, we do not doubt that, the problem is a lot of the services the UK CAA used to do in house were along with other European countries divided up with individual countries taking on certain tasks, after all there is no point every country doing the same task. When we leave and are no longer part of EASA we will have to take on those tasks again that had previously been "outsourced" to Europe. Something we probably no longer have the staffing for, or staff not necessarily sufficiently knowledgeable in those fields. That and traditionally the CAA has been looked upon as financially self supporting through fees etc, one has to wonder who is going to pay for all of this...... And I think we all know the answer to that one!
