(I'm not sure that's a feature or a problem!) But it means we have pretty detailed coverage of the entire world. Directional airport lighting that smoothly changes intensity as your relative view direction changes.Sloping runways (runways change elevation like they usually do in real life.).Taxiways available for many larger airports (even including the green center line lights when appropriate.).

Correct runway markings and placement, correct runway and approach lighting.Over 20,000 real world airports included in the full scenery set.This makes FlightGear an attractive option for use in private, commercial, research, or hobby projects. Writing 3rd party extensions for FlightGear (or even directly modifying the FlightGear source code) is straightforward and doesn't require a large amount of reverse engineering. We support standard 3d model formats and much of the simulator configuration is controlled through xml based ascii files. Being an open-source project, we have made our file formats open and easily accessible.
