American pilots charged in Amazon jetliner crash
The fact that neither aircraft had a TCAS warning was a very significant
contributor to the accident. Given that both aircraft were virtually brand new, this raises a lot of questions. Mike Schumann "Guy Elden Jr" wrote in message ps.com... This story just gets more and more bizarre... based on the evidence I've seen reported so far, it certainly sounds to me like the Brazilian air traffic control system itself is solely to blame for this accident. http://www.cnn.com/2006/WORLD/americ....ap/index.html -- Guy |

Mike Schumann opined
The fact that neither aircraft had a TCAS warning was a very significant contributor to the accident. Given that both aircraft were virtually brand new, this raises a lot of questions. Doesn't TCAS need surrounding transponders to be interogated by radar? If so, then does TCAS work in an area without radar coverage? -ash Cthulhu in 2005! Why wait for nature? |

I don't know. I just read it, somewhere. -- Jim in NC |

Given how TCAS II works, it doesn't make sense that a head-on encounter wouldn't work well, even at cruise speeds. Have you ever talked to anyone that was involved in flight testing of TCAS II? -- Bob Noel Looking for a sig the lawyers will hate |

They must be right then. I only got the information out of one of the JAA (European) ATPL Instruments textbook which is used to prepare for the ATPL exams. or you can look here and see what they describe as the learning objectives Bottom of page 32 of 41. http://www.jaa.nl/licensing/jar-fcl/...pla_frame.html |

"Bob Noel" wrote read it where? If I knew, I would have gone back and quoted it, here! g That is kinda' like trying to look up how to spell a wierd word in a dictionary. How do you look up how to spell it, if you don't know how to spell it? ;-) I think it was on one of the aviation newsletters that I get on a subscription basis. AvWeb, perhaps? Given how TCAS II works, it doesn't make sense that a head-on encounter wouldn't work well, even at cruise speeds. Could be the high closing speeds, the radiation paterns of the antenna, or something. I don't have any more details. Have you ever talked to anyone that was involved in flight testing of TCAS II? Nope. Like I said, I only heard (or read) it, and posted it as a very "iffy", possible-maybe-could be it-explanation. Not very definitive, don't you think? g -- Jim in NC |
