Another known developer is already making A320 series in extremely high quality and after that they are very likely going to make also 330 and 340, I fail to see how Captain Sim could complete A340 and A330 before that developer as they do already have a lot of needed code and modeling for systems from their A32- series. Airbus has some special systems that really aren't so quick things to model.

Capttain Sim should next make Classic 747, later maybe DC-8, Tristar and DC-10. From Airbus fleet they should make A300 (modern version) and A310.
