Spent the last two years working for the BBC on vairous contracts, mainly OB's for sport and events with a bit of the news and drama thrown in. Never saw a guide for producers with reference to loss of tail rotor effectivness, however I was asked if I could 'do this or that' with the helicopter to which I had to say no, with a explanation as to why. Producers/directors/ camera people (yes there are lady cameramen) aren't stupid and understand that there are some things you can't do, so as captian of the aircraft just explain to them and fly safely.
