Do microbursts even occur at FL390?
To the credit of Ian Ross (Ch9 Sydney?) I was watching the news when he came on with the old "In breaking news" and introduced the Qantas issue he only mentioned that a Qantas Airbus has called Mayday and made an emergency landing at Learmonth with passengers suffering suspected fractures. There was no sensationalism at that time. |

It could never have been an A320 as this has only a seat capacity of 148 passengers. It was an A330-300 and it carried 302 Passengers.

That's funny. I thought QF's 333's were only configured 30J/267Y a total of 297 seats. Unless QF included the crew in the passenger count. Jason

Computer 'irregularity' on dropped plane
AIR safety investigators say there was an "irregularity" in the onboard computer equipment of a Qantas plane involved in a mid-air incident between Singapore and Perth. The Airbus A330-300, with 303 passengers and a crew of 10, struck what the airline described as a "sudden change in altitude'' north of its destination yesterday. The plane landed at Learmonth, about 40km from Exmouth, without any further incidents. West Australian police said at least 20 passengers and crew aboard QF72 were seriously injured - some with spinal injuries and others with broken bones and lacerations. Two Australian Transport Safety Bureau (ATSB) investigators are on the ground at Learmonth and five more are expected to arrive there later today. The bureau's director of aviation safety investigation, Julian Walshe, says the plane was travelling at 37,000 feet and 110 miles north of Carnarvon when the incident occurred. "The pilots received electronic centralised aircraft monitoring messages in the cockpit relating to some irregularity with the aircraft's elevator control system,'' he said in Canberra. The aircraft then "departed level flight'', and climbed approximately 300 feet. "The crew had initiated the non-normal checklist response actions. "The aircraft is then reported to have abruptly pitched nose down.'' |

If the nose first tilted upwards as some passengers said (and the news report above), is it possible that the aircraft, because of its high altitude and heavy load, stalled, and then descended rapidly because of the stalling?
If that did happen, perhaps its a question of what caused the upward movement of the aircraft to start with... Also i found this FAA document regarding operations of aircraft at altitudes over 25,000 feet. It provides a small section about weather and the jet streams, and some info about CAT as well (Starting at page 12 on your PDF reader). http://www.bom.gov.au/weather/national/charts/UV.shtml - Pretty extreme UV conditions out to the NW - thats todays forecast, but it wouldn't change much between 2 days.
