For the moment, let’s set aside the vulgar discussion of money and consider whether turbine aircraft are all they’re claimed to be. Well, of course they are. Case closed. Turbines are faster than piston-engine aircraft, fly higher and since all the engines’ moving parts are always rotating in the same direction, they’re generally more reliable.
Moreover, the owner of a turbine aircraft is untroubled by that pesky problem of whether a high-octane fuel will be available and what it will cost. There’s no argument that Jet A is the world fuel of the future and it’s available in parts of the world where high-octane avgas has long since disappeared.
