Good idea, but how do you map the silhouette? It would be nice to see the aircraft's shadow change in a roll, for instance, so you can't use a static silhouette. Also, don't forget clouds -- if there are any, the silhouette has to be above them. How about this: after all scenery and clouds have been drawn, and before drawing the aircraft and panel, simply redefine the view/transform matrices so as to create a parallel projection that looks at the aircraft from the opposite direction of where the sun is -- i.e. the sun is behind the aircraft. Then draw the aircraft without any lighting, in plain grey, on top of the scenery with alpha-blending. This will darken out the shadow of the aircraft.
