PLANE DOES 360 AT 20000 FT!!!!

wrote: Without warning or reports of turbulence, an Air Canada flight en route to Toronto dipped and rotated violently, on early Thursday morning, causing injuries and confusion among passengers and the crew. Strangely enough, flight experts are still unsure about what caused the accident. "What happened aboard Air Canada flight 190," said a reporter on CBC's The National, "can best be described as chaos." According to passenger accounts, the Airbus aircraft bucked and rolled side to side abruptly, hurling dishes and people through the air. "It was weird," one passenger told the CBC. "The plane actually turned upside down without actually feeling it. There were people on the roof. Coffe and **** [was] flying all over the plane." After steadying the plane, the pilots were able to make an emergency landing in Calgary under their own power. Ten of the 88 people aboard were injured, even though the episode was over in 15 seconds. All have since been released from the hospital. So what caused the jolt? Immediately following the event, the pilot announced that the plane's autopilot program had been knocked out. But others aren't convinced. "I don't think it could have been anything other than turbulence," a Canadian corporate pilot told the CBC. "It's highly unlikely that it could have been a mechanical problem." Air Canada says that the Transportation Safety Board Read the whole story is investigating, but turbulence seems plausible. In the upper atmosphere, where many commercial jet liners like Flight 190 cruise, conditions exist where pilots cannot predict wind patterns that can lead to turbulence. The following video is from CBC's The National, broadcast on January 10, 2007 ************************************************** ******************************** Here is NTSB report on this incident. On January 10, 2008, an Air Canada Airbus A319, registration C-GBHZ, flight number 190, was enroute to Toronto from Victoria, when at 0835 mountain standard time, while climbing from FL360 to FL370, and at about 38 nautical miles south of Penticton, BC, Canada, the aircraft experienced a sudden upset when it rolled uncommanded 36 degrees right and then 57 degrees left and pitched nose-down. An emergency was declared and the flight diverted to Calgary where an uneventful landing was completed. There were 2 minor injuries to the crew and 8 minor injuries to the passengers. There were a total of 5 crew members and 83 passengers on board. The Transportation Safety Board (TSB) Canada is investigating, with the NTSB and BEA providing accredited representatives.

If you didn't know better it would be hard to tell that that was the same report the OP referred to!! Not 20,000 feet, not 360, etc -Robert |

Not 20,000 feet, not 360, etc -Robert- Hide quoted text - - Show quoted text - It really bothers me when A319s and B777s have things happen to them this radical that are "unexplained". They'll get to the bottom of the 777. But if computers had anything to do with the 319 they may never find out ... I know, I know, the testing for computer controlling flight is the best possible and all pathways are supposed to be proved. All we need is a stray cosmic ray setting a register funny, and POOF unexpected complexity ensues. Yes, this is just pure speculation on my part. I just don't trust computer systems to be 100%. Usually that's okay. Not in an airliner though. |

The official wording of the incident: http://www.tsb.gc.ca On January 10, 2008, an Air Canada Airbus A319, registration C-GBHZ, flight number 190, was enroute to Toronto from Victoria, when at 0835 mountain standard time, while climbing from FL360 to FL370, and at about 38 nautical miles south of Penticton, BC, Canada, the aircraft experienced a sudden upset when it rolled uncommanded 36 degrees right and then 57 degrees left and pitched nose-down. Of course, CAT describes atmospheric turbulence of unknown origins, so it's rather general. http://www.faa.gov/airports_airtraff...pubs/PCG/C.HTM CLEAR AIR TURBULENCE (CAT)- Turbulence encountered in air where no clouds are present. This term is commonly applied to high-level turbulence associated with wind shear. CAT is often encountered in the vicinity of the jet stream. So where was the jet stream located on January 10, 2008 at 0135Z? 0000Z: http://virga.sfsu.edu/pub/jetstream/...m_pac_anal.gif 0600 Z: http://virga.sfsu.edu/pub/jetstream/...m_pac_anal.gif All: http://virga.sfsu.edu/pub/jetstream/..._pac/big/0801/ Animation: http://squall.sfsu.edu/scripts/jet_p..._archloop.html And where is Penticton, BC located? http://maps.google.com/maps?f=q&hl=e...oc=addr& om=0 It looks like the jet stream was meandering through the area at the time, and its track shows an anomalous finger jutting to the north. Given this information, it's hard to rule it out. Even when contemplating crossing it from different angles it's difficult to imagine the uncommanded rolls to have been induced by wing-tip vortices from the wake of a heavy. |
