G'day Before Landing Check List.
I too have a few years of flying over cities (16 yrs) on Police ops day & night and all I can say is that sure single turbines are safe and the chance of having a failure is remote But it sure makes for a less stressful flight when you don't have to keep looking over your shoulder for a place to auto into or worry about height velocity curve etc. We use a helo that can fly away OEI from a 400' hover over the city no problems and that makes it easier to concentrate on the mission then having to worry about a forced landing area. OK it's more expensive but there's no way I'm going back to flying singles over cities again...I'd rather quit!
