@Danlo7,
I certainly think it would be a worthwhile buy if you're looking to expand your route network even further with 5 aircraft variants enabling a plethora of routes an scenarios around the world.
It also has quite a few features unique to only the A310 product line currently such as CPDLC, an improved ground handling set, a complete sounds overhaul and so much more you can find on the product page.
Check out the product page here to learn more about it for yourself: https://store.inibuilds.com/products/a310
You can also let me know if you have any questions below.
Cheers.
