what is the difference between the A3XX-50, A3XX-100, A3XX-200, A3XX-100R, A3XX-100F, and A3XX-C11? I figure that the A3XX-100F is a freighter. but i am confused abouty the rest. if airbus knows the names of the family craft, then why dont they know the name of the whole project? i am getting tired of calling it hte A3XX. i was hoping it would be called the A400 but that name was taken by an airbus military aircraft. How about A350?
