Aviation is a flight simulator meant to be somewhere in between accurate but complicated simulators and simple toy simulators that don't provide any level of realism. It currently features a non-linear flight model, a configurable atmosphere and sky model, and a CLOD triangulation engine for the terrain. Currently Aviation allows you to fly around in an area of around 600 square kilometers centered around the Columbia river. It can be easily extended to implement combat or air race scenarios, for example.
