helijet, interesting comment.
Which twin heli would you propose? What if it had nothing to do with the engine? Who is to absorb the on average 200 USD/hr increase in operating cost or do you propose the older light twins which might be cheaper and hopefully still fly away on one engine
out of a 50ft hover?Does South African rescue services/operators have the infrastructure and budget? What would be your minimum crew and qualification for the twin's more complex cockpit and system management? What is the pay difference in South Africa between a single engine say 1500-2000hr total heli time and a twin commander?
Having done some research myself, I think you might find the argument a lot more complex than 1/2 engines. The biggest fear I have is having twins but not sufficient budget for enough training as it might just look easier than what it is and we forget the enormous amount of training required
Let's wait and see what really happened.
