Before this thread degenerates into a distinctly Scroogey slanging match, I am wondering if any of the professional pilots or ATCOs out there can answer my original starting question, which I might restate as follows:
If I am flying a single-engined aircraft towing a large banner over central London at somewhere between 1500 and 2000 feet, is there any way that I can comply with Rule of the Air 5(i)? If there is not, then presumably I should not be there unless someone (CAA?) has given me some form of special dispensation.
(Incidentally I would cut and paste said rule here but I suspect that might contravene copyright....I'm sure most PPruners know it off by heart anyway!)
