AI have LOD modelling. Basically the further away it is the less polygons are displayed, so the resolution gets less. Ie you dont need to see the lowered undercarriage when the plane is 20 mile away so it is not displayed, as the plane gets closer more is displayed, this is to reduce overheads. The default FSX Ai are mostly flyable plans and this does cause a huge FPS hit if too many are displayed. AI dont have cokcpits, because of this you can have a lot more AI , if you use flyable planes as AI you would not be able to display a lot because of the FPS hit, and the amount of resources needed to display them.
