Let's have real numbers when discussing these things; Indeed. -- Dan C-172RG at BFM Check this out, Danny: http://www.seqair.com/FlightTest/Kil...lYourself.html Some people want to fly faster than that 130 mph Cessna of yours or in a different or unique airplane, and they don't have the experience in the type chosen for the purpose. I knew a doctor who killed himself in a Monnett Moni because he didn't have any time in it; the flight was the aircraft's (and his) first and last. Check out the graph here too: http://www.provide.net/~pratt1/ambuilt/faqhmblt.htm Experimentals are here to stay. Their safety record, just as the safety record of GA aircraft, always needs improving, but your comment is irresponsible. If you have any numbers other than sneering, please provide them. Hope this helps. |

Although fatal homebuilt aircraft accidents decreased dramatically in 2000, they increased to 19.2 percent in 2002. Historically, homebuilt aircraft are involved in approximately 17 percent of all fatal accidents." Hope this helps. Ditto. -- Dan C172RG at BFM |

From the report: The biggest weakness with the Nall report, and one which they admit in the report itself, is that they don't have "per flight hour" figures. If home builders are more likely to get out and fly their aircraft rather than let them sit mouldering with weeds growing through the landing gear, than the higher proportion of accidents means nothing. On the other hand, if the non-experimentals get flown on long distance night IFR while the experimentals get flown for local $100 hamburger runs, those figures might be covering up a much worse accident rate. We'll probably never really know the true answers, until somebody makes a long term comprehensive study of hours flown and types of flying versus accidents across the whole fleet. -- Paul Tomblin http://xcski.com/blogs/pt/ Microsoft - Where quality is job 1.0.1 |

Are you talking about your 172RG? Do they really cruise at 155 MPH? I
thought they cruised around 145 MPH. Is yours modified? I'm asking because I'm looking to buy one. "Dan Luke" wrote in message ...

According to Clarke's book, cruise for a 172RG at 75% power is 161 mph. George Patterson The desire for safety stands against every great and noble enterprise. |
