That kit would be great to have. Especially when flying a machine that doesnt even have a moving map display. But I agree that it could be used to press on a bit further when most would have turned around and gone home.(or elsewhere)
The safety of a flight can, and does mainly start at the planning stage before even climbing into the cockpit. The thing is that these great toys all cost money and unless its standard spec, not many operators these days would justify the extra cost of having it retrofitted, unfortunately.
The garmin 530 along with Wx radar gives a reasonable terrain avoidance system, but in my mind, once you're down to 'relying' on it during flight, you're already in a bad place.
