> the f-35 is also a very smart aircraft. if the quality of the 270v dc provided from the converter, or the 28v dc e&f safety power circuit is not the perfect voltage, amperage or harmonics at the aircraft plug, the aircraft will not accept the power and will not turn on when the ground crew hits the external power switch. > with the f-35s multiple, complex onboard electronic systems, the pca requirements are very difficult for the f-35. not too hot  not too cold  it has to be very dry air and at a higher pressure than normal commercial pca requirements. > this balancing act would be hard enough with aircraft mobile units, but these modern hangars have to have underground trunk-line systems with the actual units outside the hangar.   ft/defense/article/10943391/how-to- supply-power-and-air-for-the-f-35 oh and the electronics of the f-35 are getting upgraded from 14kw up to 80kw so you better buy the hangar subscription, else your pussyplane refuses to work
