does someone know what the two last numbrs in a plane version mean?
For example is there any difference between an airbus 310-304 and a 310-325? if yes, what are they?

Thank you

They are the same aircraft. The next number after the model is customer number and the next corresponds to what type of engines are used on that specific aircraft. Airbus and Boeing use different designations. I've heard Airbus's are easier.

The Airbus system only describes the aircraft version. On Boeings the last two digits are customer codes.


2 is the aircraft version in terms of revisions
1 is the engine version (CFM)
4 is the airframe / powerplant version (MTOW / thrust)

But maybe someone has more knowledge on this subject

some extra data on the second digit of the version designator:
0: GE
1: CFM
2: PW
3: IAE
4: RR
I hope this helped.
