Electric airplanes are already used in training in Europe. They are less expensive to operate on an hourly basis just because of fuel/energy cost. But they are probably also cheaper to overhaul; the Emrax motors in Pipistrels are relatively simple, and it would probably cost less to buy two and swap one out (sending the other one back to Emrax for a new bearings) than to do one thermal engine overhaul. And almost no downtime!

(I work on another electric airplane which will take flight in 2023.)

Is there anything you can share regarding the electric plane? I had a look at your profile and couldn't see any links beyond your keys.

I've flown an electric plane. Granted it was only about 60 cm long from nose to tail (and I flew it from the ground) but I can speak to its simplicity, low cost, and ready availability of replacement parts compared to ICE-based planes of similar size. :)
