Well, the CAA have a sitting Brexit commitee of very senior bods. Naturally one can't actually contact them to ask questions or direct their attention to issues they may have missed because, well, you can't contact anyone in the CAA other than your designated point of contact. Reports from the shop floor indicate the committee are paralysed by fear because Grant Shapps is now Secretary of State and he, apparently, has a history of asking CAA officials difficult questions. So, although a number of strategies have been proposed by the shop floor, in many areas the 'go' decision in any direction has yet to be made by the committee and work has not gone beyond vague statements of intent. There may well not be enough time remaining to actually complete it. Meanwhile in EASA land the EC have told the officials not to give any help to the UK and so they too sit paralysed by fear, wishing to be helpful, but not wanting to risk their jobs. I'm sure it will turn out fine.
