This is not only unrealistic, but it's like saying we need a anti-float warning so when we land we know when the planes going to float/balloon/etc..
Ironically, there is such a system out there. It's called the Pilot, and the Pilot must be properly trained, with the useful knowledge required to complete the job safely with good judgement. Lacking in any of these subject areas' can cause problems with 1/2 the cockpit working, if you are 0/2 in this case, the resulting events are catastrophic.
Nothing replaces actual real-life in the cockpit experience. Secondly, I know you can't always get all the experience in real life, so reading, learning, talking, and just generally educating yourself in the ways of our trade will make you a better pilot. There's people that just do the paces to get where they are going, and then there are those of us that dive in head-first. What type of pilot/person are you?
Finally, the whole "You are shouting because you type in CAPS" is juvenile. I feel it was appropriate in KC10's post because he's trying to get you to focus on the point at hand, that such a system, in your example, wouldn't do anything that the currently developed systems would accomplish. You are refusing to actually take in account his opinion because it disagree's with your vantage point.

Everyone fly safe out there, the fun time of year is upon us.
