Toward Autonomous Unmanned Aircraft Technology
coondoggie writes with a NetworkWorld piece that begins, "Researchers at Purdue will soon experiment with an unmanned aircraft that pretty much flies itself with little human intervention. The aircraft will use a combination of global-positioning system technology and a guidance system called AttoPilot ... to guide the aerial vehicle to predetermined points. Researchers can be stationed off-site to monitor the aircraft and control its movements remotely. AttoPilot was installed in the aircraft early this year, and testing will begin in the spring, researchers said."
I dunno. One of the things I quite like about playing video games is that nobody actually dies.
Yeah, but can they land it in the Hudson?
Even a flock of geese can put a plane in the Hudson, how hard would it be for a computer?
What you're referring to is Category III autolanding, which in CAT III C has no decision height but instead the aircraft can land completely on its own (30 m in CAT III A and 15 m in B, IIRC). More landings are done that way than not - and all landings if the weather is bad since autopilots do a much better job than humans. Now it is obviously necessary that the airport is equipped with that capability so saying that it is for emergency use is a bit of a stretch since in an emergency you might have to land wherever you can (such as on a river...) - or maybe improvise to get it to the runway despite some techincal malfunction (who needs hydraulics when you can vary thrust?). However, Airbus have begun investigating the possibilities to create a "hijack button", which pilots could press in case of a hijacking and then the aircraft would automagically set its transpoder appropriately, notify ATC and land at the nearest CAT III C runway regardless of what is done with the flight controls since then ("sorry Mr. Terrorist, it's out of our hands now"). AFAIK no aircraft currently in service could, however, be equipped with that without some substantial changes (well, perhaps the A380 could, since it's not only FBW but also power-by-wire).
I believe that it would be more than niche applications. There are many areas in aviation where UAV's would be a boon.
For example, UAV's could be used for fire suppression applications - Whenever there are forest fires (or even the threat of), UAV's could be prepositioned and in the air in a matter of minutes.
Crop Dusting - UAV's could perform this function with better precision, for longer hours.
Post/Parcel delivery
Search and Rescue
All these applications are prone to pilot fatigue and are dangerous commercial applications - I am sure there are many, many more applications where UAV's would make more sense and improve aviation safety.
