Aircraft systems require higher current ratings to operate the various loads/systems. To accomodate the high power, 20 KW to 100 KW generators into a small aircraft, and also to accomodate, larger size electrical equipment like servos, power dsitributors and electro-mechanical devices, 400 Hz is the chosen frequency. As 400 Hz reduces the size of electrical equipment considerably. 50 Hz would require HUGE aircraft.

Thank u.

The generators and motors can be smaller and lighter. 400Hz power is also much easier to filter when rectified.

4 hundred hz is extremely "sparkling" AC. it somewhat is mandatory to have such noise loose voltage to potential such gentle gadgets with the aid of fact the gyros in inertial navigation structures and many laser applications.
