I don't know if it normal, but how come it's impossible to power back the plane with 6 engines ?  The plane move by itself forward on idle and can't power back full thrust reverser !  To me it's not normal. Mostly all planes can power back. Increase the engine power on reverse please and try to fix the fact it move forward on idle.

Based on our knowledge they always pushed the aircraft back with their own pushback truck. So we would say no, it isn't possible.

 

Ok thanks.

I just received the confirmation from Antonov that the AN225 reversers are not used to power back the plane. Only a tow truck.
