Well, I certainly hope you [Fast Ben] are a better pilot than I was (which wouldn't be difficult), but you didn't consider the width. If the runway is reasonably wide and you control your approach properly, then you would be landing straight and slowing down to a safe taxi speed well before you need to start following the curve.
If your approach is bad, then you're supposed to go around anyway. From that perspective it might actually increase the safety if there is a clear buffer zone around the airport. I still remember the time I was on final and a sudden crosswind lined me up over the parked planes... However, the "sudden crosswind" is a case that this design would still be vulnerable to, so you still need planes and pilots that can handle such situations. (No mention of "sudden" in the comments, but that doesn't much surprise me on Slashdot these days. Maybe I should be surprised to see another pilot here at all? A lot of today's comments are from people who know little whereof they speak... (Though I still miss the "funny" more.))
I think the instrument landing part is where you earned the "insightful" mod, though I doubt the moderator knows why. However, I think it is basically a software problem. Yes, you'd need more beacons, but mostly you'd need to be able to interpret their data from more orientations. I think you'd have to calculate every instrument approach for the current conditions, and probably for the individual plane.
