When doing a forced landing, is the aircraft equipped with sensors to allow it to spot the optimum spot to land given that there may be traffic on the ground? In picking which patch of water, would the computer be able to see all the boats/ferries/whatever? If deciding to land on a highway, could it do its best to pick an empty patch and be mindful of lamp posts and other street furniture?
As for the transatlantic glider, one of the issues with that was that it was necessary for the flight crew to do all the fuel calculations, I understand that the software was modified after that incident so that it will flag an alert if the apparent rate of consumption is higher than can be explained by the engine settings.
Having the computers run checks and at least ask "are you sure?" would prevent some things happening. Wasn't there one crash where the autopilot got programmed for constant rate of climb and did its best, right up until it stalled. Ideally it should have queried whether the programming was sensible or not so the pilot could review what he'd just asked for and why it didn't think it was a good idea.
