I've added a new "range" animation type for 3D models and have also added a top-level range selector for each 3D model. See docs/Model/fgfs-model-howto.html for details, or take a glance over Aircraft/c172/Models/c172-dpm.xml in the base package.
I've also modified src/Model/acmodel.cxx so that the aircraft model has the same clip plane as the scenery in external view. It works on my computer, at least -- the plane can taxi in front of or behind objects and you see the right thing from the tower.
