There even exists software for auto-planning a route for a dead stick landing: Xavion, by the author of x-plane. I seem to remember reading like 4 or more years ago, that there was an experimental autoland system actually powered by that software, and could autoland in a dead stick situation. EDIT: Found the experimental engine-out auto-land system based on the same technology as xavion: It is called the VP-400 by Vertical Power. I'm not sure if it ever became a purchasable product.
