My personal deal with a twin is the ability it affords me to limp to a emergency landing area of my choice (ie: continuing flight to an airport 30 miles away vice 11-12--or whatever the glide is on the single engine plane).
If an engine fails on TO in a King Air you are still going (at least every one I have flown this was not an issue).
SO, other than fuel and maintenance, why would you want to fly a SE plane when given the choice of a ME??? Please enlighten me because I am feeling stupid.
Also, if your argument is the reliability of the PT-6 or whichever turbine is on the Pilatus or other SE turbine plane, don't you think the fact that aircraft manufacturers are producing more of these type of planes will cause the reliability statistics to lean the other way (when you have more of these planes not being maintained properly, etc..)??
Thanks
In my opinion I believe that a multi-turbine is safer (especially one with auto-feather) than the single PT6.
Pilatus markets on the stat that single engine turbine engine loss have had historically a better survivability than multi-turbine losing one engine.
I dont know where they got these stats, but they publicize it on thier brochere.
The weakest part of the PT6 engine is IMHO the FCU, fuel control unit. In the rare instances that PT6 engines have failed it has generally been because of the FCU. I think in all single engine turbines there is some type of MOR, Manual override lever that is a direct linkage to the fuel metering valve, in case of a Py leak.
With that said, I do believe that a single engine turbine is safer than a piston twin. If your flying piston twins for hire, I'd imagine youre at or "very close" to your gross. Just being in a beat up old piston twin having considerably less power than a turbine brings you much closer to a dangerously unfavorable condition. Single engine T/O are much more critical, and the threat of a VMC roll is more ominous.
safest 767, 757, 777, G5, G4, Citation X (High thrust to weight ratio turbojets, unless you are making a water landing, than something other than an underwing engine mount)
