Hi I am in São Tomé and Principe for break and saw some great planes and flew in and out of both airports. I then wanted to fly them in IF but I was very unimpressed by the scenery and that there are no parking spots.
The airports in Infinite Flight are made by the airport editing team, and direct requests are not accepted.
If you want to be a part of the team and help to contribute, you can read more about it here:
Regarding the rest of the scenery, it is currently with the highest resolution scenery we have in the app. 15meters/pixel. It’s something we hope to be able to improve in the future though!
