Well dear fijodor, how about you doing some research work? Bit lazy aren't we?
Seriously, don't you think I tried? Unfortunately the CAA of UK does not provide this information easily. If you search on the aforementioned site for SWP, it does not find anything and suggests to try "setting wing paper" which makes no sense at all to me and surprisingly does not find anything useful either. Therefore we need somebody who has at least an idea, where the CAA does hide this information or the books latest issue.
Satisfied?
BTW: Being closer to the UK than to Canada does not mean, that we understand their way of thinking better than yours. The Brits way of thinking is puzzling to the rest of the world.
