>>1652720>You would need a pretty large voltage to get arcing between the aircraft and groundYou would also need a pretty large voltage to create plasma propulsion on the scale needed to move a commercial airline.
>but aircraft already have this problem and have ways to deal with it.Yes, but not quite on the scale this would have. Best case scenario you can isolate the charge to the engines themselves, which will have to be overbuilt to accommodate large electrical potential anyway. Personally, I would look at jet grounding procedures and the methods used by helicopters that work on high-voltage lines in order to develop a safe grounding maneuver for this style of propulsion.
All this ignores actually storing or generating the needed amount of energy to put out that kind of thrust on a moving aircraft.
