Boeing has C/N (construction numbers) and F/N (fuselage, line numbers).
cn numbers are the all produced airplanes of the company, since the company started. And FN numbers is the number of all produced planes of a line (all 777s).
But I have seen that Airbus only numbers the produced Airplanes in the families (like the A340, 330 line). They do not have numbers for all produced airplanes. But the thing is, they call the number of the amount of family produced aircraft the CN number. (they call the FN number the CN number) Why do they do this, and why is there no proper CN number?
