Are you asking why the ac standard is 400 Hz for aircraft? It is because transformers and chokes can be much smaller and lighter at the higher frequency.

airplane systems require greater present day rankings to function the diverse plenty/systems. To accomodate the severe ability, 20 KW to one hundred KW turbines right into a small airplane, and additionally to accomodate, better length electric kit like servos, ability dsitributors and electro-mechanical instruments, 4 hundred Hz is the chosen frequency. As 4 hundred Hz reduces the scale of electric kit appreciably. 50 Hz could require extensive airplane. Thank u.

400 hz is very "clean" AC. It is necessary to have such noise free voltage to power such delicate devices as the gyros in inertial navigation systems and many laser applications.

don`t forget the 3 phase part of it

Higher voltage allows the same amount of work to be done with fewer amps. This allows for smaller electrical components, thinner wiring, etc., saving weight.

It's on the way. Listen to 406.0 for emergencies, in a couple years. 121.5's on the way out.
