Banner Towing
Just curious as to what it takes to be able to do this. Yesterday, Sunday 17 April, there was a huge blue commercial advertisment, about the largest airborne banner I've ever seen, being dragged across Central/East London by a red helicopter for about 2 hours continuously, from 1700 to 1900 local, at I'm estimating 2,000 feet.
Now not being a rotary man I don't know how the regs are different for them. But I imagine if I request to fly myself single-engined in Class A airspace across a fully built up area tying up Thames Radar and the London City departures for this length of time there might be a few words said.
I know if he gets an engine failure he can auto-rotate down or manage to get clear if he is twin-engined, but I presume he would have to drop the banner in such circumstances. And as I said, it was huge.
