There should be a ban on aircraft that are not allowed in the countries. Example the Comac is not allowed to fly in EU and USA, same goes for other aircraft. To make ik more realistic game we should ban those aircraft in those countries.
Lots of Russian planes that are not used in EU/USA are flying in new worlds. I dont see Antonov or Tupolev 204 in the real world outside some far away russian parts. Even the Superjet is only flown in Russia these days, although this aircraft is approved by the EASA but not the FAA
