Yep -that's exactly the sort of thing I was referring to. The Panavia Tornado uses a lookahead radar to evaluate the terrain and build an elevation profile, upon which it overlays a ski-toe curve flight envelope. The terrain avoidance system ensures the flight envelope avoids the terrain by looking for intersections of the two curves:)
A fully featured terrain avoidance system would be expensive within FG, in terms of resources, but I think simpler and less resource hungry schemes are possible, certainly in straight-line flight, and which would be a great improvement over the current facility.
