Given the recent crash near Athens, Greece, and the Payne Stewart LearJet
incident... I'd say we have a long ways to go. "Bob Fry" wrote in message ... Not my statement. See http://www.longbets.org/4 What sayeth the group wisdom? I think eventually there will be pilotless aircraft, the question is when. |

This reminds me of a movie I watched some time ago. Can't remember which one, could have been 'Right Stuff'. The aircraft was designed to fly without pilots, but for some reason they elected to have pilots in the aircraft. But there were no windows for the pilots. So, the pilots vehemently objected to it, and wanted to hand fly the aircraft. Then I think there was some discussion of putting a monkey in the aircraft instead of pilots. Any way, in the end the pilots won, and they had to redesign everything with windows and controls. The movie title is correct, however the cited example referred not to an aircraft but to the first manned American spacecraft, the Mercury capsule. Greetings, Markus |

"Bob Noel" wrote in message ... What we don't have is the ability to formally prove the correctness of software. We DO have the ability to prove "correct enough". That is, we have engineering strategies designed to ensure correctness to some given degree. These are the same techniques that were used for the space shuttle computers (though, unfortunately, not for recent unmanned space probes), and similar techniques are used for existing automation in aviation. It's true that we don't have mathematical proofs for correctness. Of course, it's widely believed we may never be able to have that. But physical engineering suffers from similar limitations, and it seems to get by just fine. Theoretical design can always be undermined by human implementation, but there is an idea of "good enough" in both types of engineering. You simply design in assumptions of human failure of implementation. I don't see this as a fundamental barrier to pilotless airliners. In the same vein, piloted airliners are "good enough". The number of catastrophic losses are quite small in comparison to the number of flights. There is no evidence that aircraft piloted by computer would fare any better, much less signficantly better. As I see it, the question isn't whether a computer can fly an airplane from A to B, but whether it can handle the unanticipated problem successfully. This amounts to being able to anticipate the opportunities to fail, and the possibilities extend well beyond the ability to predict them (the DARPA land XC example demonstrates that this may be an issue). While computer-piloted aircraft may eventually be able to succeed "most of the time", human-piloted aircraft have done so for quite some time. So, I question the benefits of such an effort. Neil |

As far as high jacking: I think that a pilotless plane would be more
secure. The designers could put in a code or something and make it impossible for a hi-jacker to take control of the plane. Of course he could still blow the damn thing up in mid-flight, but he wouldn't be able to fly it into the WTC or such. |

Given the demonstrated abilities of hackers, I think it might make hijacking easier. Quote Then instead of having 3 or 4 hijackers taking 1 aircraft, we will have 1 Hacker taking over several aircrafts and flying them wherever he wants |

... In the same vein, piloted airliners are "good enough". The number of catastrophic losses are quite small in comparison to the number of flights. There is no evidence that aircraft piloted by computer would fare any better, much less signficantly better. What would you consider "evidence"? It's not like we've got airliners without pilots that we can use for comparison. There's no question automation would avoid certain kinds of losses; the valid question (without an answer for the moment) is whether human pilots balance that out with actions that a computerized pilot could not take. I am sure the pilots' unions will invest great resources in showing that human pilots are better. But I'd just as soon see an independent source for that analysis. Saying "there is no evidence" may be true, but it doesn't answer the question. It simply describes the current lack of information. As far as "good enough" goes, that's a social issue. For the time being, I'd agree things are "good enough", especially the distrust that the public would have with an fully automated airliner. But long-term, airlines are looking at two things, at least: * Overall loss rate * Cost of operations Both of these affect their bottom line, and if they can save money by using airliners without human pilots, they will. They will, of course, have to take into account the effect making that change will have on ridership. But if the airliners can convince the public that taking the human out of the equation is safer, that won't be an issue. Pete |

There is no evidence that aircraft piloted by computer would fare any better, much less signficantly better. What would you consider "evidence"? I meant "evidence" in a loose way, not as legally valid terminology. ;-) So, any vehicle capable of operating autonomously over long distances and time could provide some "evidence", one way or the other.

I am sure the pilots' unions will invest great resources in showing that human pilots are better. But I'd just as soon see an independent source for that analysis. I see it a little differently. The contest is not between humans and computer control a computer can fly an airplane autonomously from point A to B. That's a ways off, considering the current state of AI. As far as "good enough" goes, that's a social issue. For the time being, I'd agree things are "good enough", especially the distrust that the public would have with an fully automated airliner. I also don't see this as an issue of public trust, because the mindset that we have about such things today is not relevant. By the time AI has achieved the required sophistication to pull this off, I'd expect that autonomous machines would be quite the norm and everyone would be able to accept the introduction of autonomous airlines as the next logical step, pun intended. ;-) But long-term, airlines are looking at two things, at least: * Overall loss rate * Cost of operations I am skeptical that the overall loss rate would change much, for the reasons I stated in my last post. As for cost of operations, it seems to me that support for autonomous aircraft would require an even larger and more costly infrastructure than the airlines have now. Who is going to service and pre-flight these systems? Considering the number of service stations capable of dealing with the problems identified by the computers in our cars and the expense of repair, I don't think the airlines can expect to save much (if anything) by eliminating pilots.
