e57,
The airplane business industry is conservative, that's for sure...
Winnie,
Aha, I suspected that you would run the motor hot.
I can see the point of "wild frequency". It was the way power plants were built before the concept of "power grids" was introduced. Small plants, like wind mills, are now using it. (Again)
Could this mean the end of 400 Hz?
Raw "wild frequency" power from the engines, used for various aircraft system while all cabin loads (lights, outlets, galleys, entertainment system) will run on ordinary 120V 60Hz or 230V 50Hz ground power? (A coffe machine or a TV screen for an airplane is EXPENSIVE)
