Boeing 747-8

I just noticed that the Boeing 747-8 has got the nosie category stage 2 and not stage 4? is that correct?

How knows. I know that they are usn different tech to make it quieter.

No, it is not correct and in fact wouldn’t even be legal in reality. The B747 is wrong, too. But as far as I know we do not have any Stage 2 restricted airport at the moment, so this has no influence of any kind in the game, so no need to change it quickly.
