Do you mean stuff like this: http://www.spatial.plus.com/fgfs-screen-003.jpg http://www.spatial.plus.com/fgfs-screen-005.jpg http://www.spatial.plus.com/fgfs-screen-007.jpg http://www.spatial.plus.com/fgfs-screen-009.jpg http://www.spatial.plus.com/fgfs-screen-017.jpg ? These are all just sub-models added to the aircraft 3D-model, but then placed in the scenery as required, for the landing airfield (chosen at run-time), using the built-in Nasal geo fuctions, whilst also using Nasal to prototype the algorithms.
