"If you follow the rules and keep your paperwork up to date you will have no problems"
There speaks a man who knows all the rules then! Sorry Rod1 but it is often not so easy, especially when the CAA will not or cannot give you a precise definition of something. You are then left with, and I quote, "submit your paperwork and we will make a ruling then" How does that aid safety? Would it not be better to have a definitive answer first, in writing, so that you have the comfort of following the rules. Problem with that is then someone has to sign something that may, just may, be prejudicial to some unforseen circumstance in the far distant future and the CAA just cannot be put in that position.
Cynical? who me?
