Synthetic vision actually gives you a tunnel when the approach is activated. You intercept the tunnel (if vectors), stick the momentum marker in the middle of the tunnel, and you will land on the runway. traffic appears on the Synthetic vision too along with any other pertinent info.
It is pretty funky when this if from a GPS LPV approach, and makes you realise what really is possible these days (unfortunately not in Europe for another 20 years).
I'm all for anything to aid situational awareness. My buddy flew into a mountain on an IAP in a Seneca, obviously lost SA and killed 5 people. GUARANTEED if he'd been flying one of these aeroplanes, this would definitely not have happened.
The problem is when that person goes beyond the limit and pushes their luck.....
