If all midair collisions were eliminated...

John Smith wrote: The total accident deaths per year in the US is only around 38,000. Only? Well, that's on the order of one in 10,000 people per year. That actually sounds pretty good, considering around 140 people out of 10,000 will die of *some* cause during that year. Of course, the context of my comment was that 38,000 isn't much more than 30,000. Mike Beede |

Even to inattention and intoxication infrastructure is the answer. http://www.katchuptv.com/?video=4781 The video shows what happens if a driver gets knocked inconscious at 250 kph. What if he gets knocked outconscious? |

Then you live not in a technical world. Been in the highway/road building technical world when you were peeing in diapers. http://boingboing.net/2010/01/14/cra...1959-chev.html And you live in a grammar and spelling challenged world, not to mention a tangential world where you can't keep to the topic. |

Of course, you'd have to ban ALL transportation. Of course, sitting on your ass watching ESPN and MTV can kill you in the long run, too. Lemme guess: college student? |

"brian whatcott" wrote in message ... brian whatcott wrote: What cost is there in attempting to eliminate midair collisions that offsets the loss of life that they entail? If the US road speed limit were reduced from 70 to 65 mph, perhaps 30,000 lives would be saved annually. Isn't that worthwhile? We have apparently decided NOT. Brian W My numbers for road deaths were way high. The allowable speed would need to drop much more to provide these life saves - to perhaps as low as 15 mph?? The time series data is much more encouraging: fatalities per million cap are dropping. One supposes that belts and bags play a role. Depending on the source, the international data is not flattering for US drivers - but then - they have long distances available. I wonder if international road systems are built primarily for transportation, or for generating revenue from fines and/or deliberately choked to force people into mass transit like ours. http://www.thenewspaper.com/rlc/reports/rlcreport.asp http://www.ite.org/ http://www.cato.org/pubs/catosletter...letterv6n1.pdf |

And correct: there are some spelling errors, most of them due to typing too rapidely or thinking in several languages at the same time. I'll work on it. Tom De Moor Lots of grumpy people on this thread... Surely the point of the original post was to show that flying entails risk to life. It's difficult to eliminate all risks, but working to reduce the biggest risks will likely lead to the biggest benefit in terms of precious lives saved. Midairs don't contribute much, compared with all other causes, of your chances of dying in a glider. |

If it were possible, sure, but many _more_ lives could be saved by putting the effort elsewhere. It's a matter of allocation of resources. I don't have the numbers, but you're probably right. The restrictions on flying that an effort to completely eliminate midairs would mean that pretty much everybody stays on the ground. True of many safety measures if they are carried to extremes. |

For example, addition of some machine intelligence in the flight control systems that takes into account not just pilot demands, but limits to those demands imposed by the current flight regime, and is active through all phases of flight so that it aids and/or limits controls to controllable regimes. Automation has its own universe of failure modes that is just as difficult to eliminate as human error (because it is derived largely from human error), and digital systems in particular have catastrophic failure modes that human-based systems do not share. So be careful what you wish for. In any case, Airbus is trying to embrace the philosophy you espouse, not always successfully. And to a significant extent, the greater the automation, the less interesting the activity. It might be pragmatic to automate commercial flight, but flying for pleasure would probably suffer from excessive automation. The statistics currently indicate a greater probability of human failure than machine failure, so this seems likely to yield a net reduction in the accident rate. There are no heavily automated systems to compare to, and existing automation systems have not been analyzed in detail, as far as I know. |
