Tourist, firstly I think you are trolling.
You are concentrating on the technically achievable but ignoring the practical integration of an unmanned aircraft into the existing system. Flying a combat aircraft in a war zone is a totally different environment to a civilian airliner full of passengers operating in proximity to other aircraft, most of which will be under manual control.
How would your fully autonomous helicopter deal with spurious but false warnings such as a tail rotor chip caption (or even double engine chip indication coupled with a main gearbox chip caption, both of which I've seen) over totally inhospitable terrain? I've flown helicopters for over 35 years. Many, if not most, of the "serious failures" I've experienced have actually been spurious warnings.
On the other hand, I've seen inflight total loss of output from both channels of the aircraft's data acquisition system which are supposedly mutually redundant. I've also seen real warning captions that were not in the pilot's flight manual or maintenance manuals. The aircraft manufacturer had to take further specialist advice on what these captions meant; this took some days. How would an autonomous aircraft deal with these situations? The problem is, just like the programming of an aircraft simulator, rubbish in = rubbish out and if there's an off-model event, the outcome of an automatic system is as uncertain as that of any human pilot.
