Thanks for your advice Michael.
After your reply I realized my scenery was still empty, without any sort of traffic or life.
So, to begin with I had to make a new bgl file for fixing my AI air traffic issue.
These pictures to show the result.
Default AI Aircrafts at BNOG Gohelanya International.
The Antonov AN-225 waiting for takeoff at BNOG Runway 08. Note the tiny AI Mooney Bravo, waiting too! :D
I am not yet confident with freeware AI aircrafts, I am still using default ones.
Also, I have to do the population density map, because highways are still empty.
