So, Kevin, what are you doing hanging around an aviation group?
"Kevin Hill" wrote in message news:f_hNb.17218$XD5.15970@fed1read06... Let's put it this way. A pilot flying a commercial jet or airplane is at his job. Not that that is a guarantee or anything. He's also responsible for all his passengers, and will loose his job and livelyhood should he do something stupid. As several pilots have done, who reported for work drunk. A professional airline usually has many people involved in the operation of a flight, and any one of those people can pull the plug on the pilot or the flight should they be doing something stupid, like drinking, or perhaps trying to take off with a few nuts and bolts loose. The theory being that the chances that multiple eyeballs will see a problem is higher. And maintenance crews and staff are dedicated to keeping the planes flying. A professional pilot also probably has lots more hours under his belt stepping into the jets cockpit than many private pilots. And, has experienced his share of issues, problems and perhaps emergencies. That experience means something. As to your remarks about who designed these planes. Glad they had supervising engineers looking over their shoulders, and glad they had engineers working under them to cover their mistakes when they were too hung over to do their jobs. Point being - one person can make a mistake and not recover from it. Many people can work on a project, and every person gets a chance to catch a mistake prior to it getting loose. Not that it's perfect. Just better. Finally - not knocking pilots. Just saying that I'd have a tough time getting into a plane with them and literally trusting my life to them. Particularly when their flight experience may be measured in tens our hundreds of hours. Flying may still have lots of lessons to teach them.

At least when I fly commercial, I know that they have at least had some kind of professional training (I hope)! Then I'm sure you'll be thrilled to hear that some of the engineers that designed those airliners, and their engines, were classmates of mine 25 years ago. Some of whom I helped carry back to their dorm while they were puking their guts out after overindulging at the weekend kegger because they were so tripped out on LSD that they didn't know how much they were drinking. Think about that next time you get on an airliner! As for the "professional training", do you think we were taught to fly by amateurs? Or just spent enough time with MS Flight Simulator that we decided to get in a REAL plane? BTW, I'm willing to bet that most private pilots could safely handle and land any airliner that's flying today. Should the need arise. -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBQAWuZpMoscYxZNI5AQFchgP+IeBl8ovaD9tSuiF8+9 fq3YsksJbgX+TI nhtmYcC9YqIwJRZIhn1aPG4K3ldsltPF34vf9++iCwp92Xr3gf 7yM8zhlbBdtbEH PTp9ieFklGl6oqHcNP0WAyUBqZxOT16IyCEHkePOWRwqn4mY9n zwSPqQIDf8TJz4 /gnke18Bsu0= =27vL -----END PGP SIGNATURE----- |

It would be more accurate to say that there is one fatal accident (as opposed to fatality) every 76,000 hours of flying. That would be one fatal accident every 760 years for people flying 100 hours per year. However, most people fly much less than 100 hours per year. They also do not have long flying careers. Most people fly for less than 20 years of their adult life. And if you eliminate the obvious Darwinism fatalities it is even safer. Just like automobile accidents. Don't do the things that kill most people and it is safer than raw stats would suggest. Ron Lee |

Enjoying the talk and listening to you guys swap stories. Good stuff!
Honestly - I do quite a bit of "sim" flying - and seeing how things go in the real world is kinda sobering. And - I didn't say that I wouldn't fly myself somewhere, or take passengers myself if I was a private pilot. Just that I don't know anyone right now that i'd fly with.

To put that in perspective, for | 40-year-olds with a life expectancy of 80 years, 6.3 hours of life are lost | for every hour flown. For 10-year-olds with the same life expectancy, 11 | hours of life are lost for every hour flown. | Wanna check your math, there, Gary? And maybe you could mine the data for a little more interesting information. You do come up with good stuff. It would be more accurate to say that there is one fatal accident (as opposed to fatality) every 76,000 hours of flying. That would be one fatal accident every 760 years for people flying 100 hours per year. According to p. 1 of the Nall Report, there are 1.22 fatal accidents per 100,000 GA hours. That's one every 82,000 hours. According to p. 5, personal flying accounts for 48.1% of GA hours, but 70.8% of GA flying. That comes to one fatal accident per 56,000 hours of personal flying. That's every 560 years at 100 hours per year, or every 28 years among 20 pilots who fly 100 hours per year each. So as I said, it's roughly 1 in 20 within 25 years. You're right though that I was conflating fatal accidents with fatalities. So the probability in question is the risk that *someone* will die in the plane you're piloting--not necessarily you. --Gary |

You're right that the statistics reflect an unknown number of dumb decisions that you and I might never make. But they also reflect an unknown number of instances where a pilot escaped harm by exercising better skill or judgment than you or I possess. We don't know which factor predominates, so we don't know if our personal risk is greater or less than what the raw stats show. --Gary Ron Lee |

news ![]() personal flying accounts for 48.1% of GA hours, but 70.8% of GA flying. Oops, that should say "but 70.8% of GA fatal accidents". |

Makes you wonder if we are going to get a an upsurge in accidents now that so many people are learning to fly again. Nall is not the only source on aviation safety. Other reports have broken the accident rate down by type of aircraft. The Cessna 152 and 172 have much lower accident rates than average, for example. Some models approach the safety record of airliners, but they tend to be flown only by professional pilots. |

![]() "C J Campbell" wrote in message ... It would be interesting to know whether accidents cluster around those who don't fly very often (less than 50 hours per year) or those who fly a lot or even professionally. I notice many fatal accidents in the NTSB database note that the pilot was not current...perhaps more than half (sorry...I've not run empirical analysis). OTOH, there seems to be a lot of pilots with thousands of hours. Overconfidence of experience? |

Wow, I asked a short question and this thread has blown into dozens
of postings. I'm glad I'm not the only who was interested in talking about this. Also I would like to thank everyone for your thoughts. I guess most of my friends will never go flying but that is their choice. Gary wrote: According to p. 1 of the Nall Report, there are 1.22 fatal accidents per 100,000 GA hours.

Is it me or do others find all these stats just completely useless after a while since it appears that if you add all the percentages up it comes out to 14,284% (Gary I'm not pointing this next comment you *at all*) I'm starting to believe the old saying, "Statistics don't lie. The people who use statistics lie." Gary's example is pretty clear cut but most of these reports are quite comfusing. (NOTE: I took 9 semesters of math above Calculus I so my math is not exactly lacking) Gerald |
