Hi, I just committed an update to simgear to add support for a scale animation type (in addition to rotate and translate.)
If someone can tell me where the model animation is documented I will update the docs as well. One use for scaling that comes to mind is to do something analogous to Lee's shadow trick to impliment a crude landing light. Instead of drawing a black translucent shape which darkens the ground we could draw a white translucent shape that lightens[1] the ground. However, since we are simulating the intersection of the spotlight cone with the ground, we need to expand the size of the shape as altitude increases. This doesn't take everything into effect, but we could probably fake pitch and roll effects enough to be believable in the normal flight range.
