most people would like to have a simple cookbook, a video, a point and click interface in order to get what they want. Life should be simple. This is what marketing tells us. However the flightsim world does not work like this. You need to spend some time with reading and understanding how scenery is built in Aerofly FS2. This starts with the image of the world, the orthofotos which lay on a terrain mesh and ends with the cultivation of that image with houses, trees, lights, airports and other scenery. Believe me there will sooner or later be questions but hopefully clear questions and not general questions like how do I make scenery. Most of them have been answered already but it is not so easy to find them. People here are willing to help but more if they feel that someone has spent some time with the topic and has a basic understanding.
For AeroScenery there is a good guide available here.
Please also read the quite long thread in this subforum here about AeroScenery.
Information about the Aerofly Cultivation/Scenery Editor is here.
To create a simple airport for your scenery check FSCloudPort.
Don't forget the wiki where you will also find some tutorial videos.
And then if you have a question: first look where it should be placed, in which subforum (there are only three). Then open a new thread with a title that clearly explains the topic (this will help other members with the same problem to find it later).
It is fun to bring life into Aerofly FS2 and creating personal sceneries but it will not happen over night and some time is needed in order to get familiar with it.
