Should be, yes.
Yonks ago I used my mains powered shaver on a plane, it didn't sound
happy, though it still did the job.
I'd have expected that sockets which were intended to be used by the public,
rather than for avionics etc, would be 60 Hz (or 50 Hz for 240 V) for that
very reason, even if it has to be generated by rotary converter or
rectifier/inverter from the plane's own 400 Hz supply.
