From CAP393, Section 2, part 45 "Flights within aerodrome traffic zones"
45-(2) "An aircraft shall not fly, take off or land within the aerodrome traffic zone unless the commander of the aircraft has complied with paragraphs (3), (4), or (5), as appropriate"
I'm not going to paste in paragraphs (3), (4), and (5) ....because I think it's about time some people here refreshed their memory of Air Law ! Talk about picking up bad habits, remind me not to fly with some of you !
