Again I have to agree with the logic of Headsethair.
Now here's one for the 'more engines the better' brigade.
IF there was a three engined small helicopter would that allow unrestricted flights over water. Or four, or five.
Odd isn't it that we fly 100+ people across the Atlantic on just two engines. It used to be done on four engines.
So why are the aeroplanes flying with fewer engines than before and helicopters are requiring more engines?
What is the insurance providers view of the risk comparison between twin and single engined operations over water?
Just to be even more critical. Was it not a twin engined helicopter that crashed at an RN airfield. Nowt to do with the number of engines fitted but that it only had one tail rotor. B407's have only one tail rotor and they are flying over lots of water!
