"1) The night lighting is a bit dissapointing"
Can you be more precise? I'm just a normal user and I personally think the night lighting is stunning and spot on.
"2) There are heavy AI aicraft at airports where they don't belong"
This can be explained : airports are mainly created by volunteers through the scenery gateway. Almost 4000 people throughout the world created an account, downloaded WED, the scenery development tool provided by Laminar Research. They read the manual and watched tutorials on youtube to learn how to improve airports.
The result is directly in X-plane 11, being updated regularly.
An overview is available here :
Everything is centralised in real time here :
Settings the aircraft size has not always been possible, because Laminar Research regularly implements new features. It takes time for people to describe these new parameters, the more so as there are still 6 airports out of 7 that need a decent design. All this to say : if you really want an airport to be better designed, the fastest way for you to get it is to do it yourself. And the good news is : it is possible!
3) "do your vendors have the latest version as i am planning on getting mine from the Fltsim Store"
I'm sure the version they sell can be updated, like every other. To update it, you need to download X- plane installer on X-plane.com :
Personally, I would buy X-plane from X-plane.com because it's Laminar Research website and I don't like to buy through intermediate resellers.
