AirAsia Flight QZ8501 climbed fast then stalled (Indonesia)

The AirAsia plane that crashed into the Java Sea last month with 162 people on board climbed at a faster than normal speed and then stalled, the Indonesian transport minister said on Tuesday...

Flight QZ8501 went down on December 28 in stormy weather, during what was supposed to be a short trip from the Indonesian city of Surabaya to Singapore.

Indonesia's meteorological agency has said bad weather may have caused the crash, and investigators are analysing the data from the jet's black boxes before releasing a preliminary report.

Just moments before the plane disappeared off the radar, the pilot had asked to climb to avoid the storm. He was not immediately granted permission due to heavy air traffic.


"In the final minutes, the plane climbed at a speed which was beyond normal," transport minister Ignasius Jonan told reporters, citing radar data.

"The plane suddenly went up at a speed above the normal limit that it was able to climb to. Then it stalled."

Earlier at a parliamentary hearing, he said radar data showed the Airbus A320-200 appeared at one point to be climbing at a rate of 1,800 metres a minute before the crash. There were several other planes in the area at the time....................http://timesofindia.indiatimes.com/world/rest-of-world/AirAsia-Flight-QZ8501-climbed-fast-then-stalled-Indonesia/articleshow/45956301.cms

  1. AirAsia-Maschine flog vor Absturz rasanten Steigflug...

    Ein Pilotenfehler oder technischer Defekt als Ursache für den Absturz ist wahrscheinlich. Ermittlern zufolge befand sich das Flugzeug in einem ungewöhnlichen Steigflug.

    Vor dem Absturz der AirAsia-Maschine bei Indonesien befand sich das Flugzeug nach Behördenangaben in einem ungewöhnlich rasanten Steigflug. Das teilte der indonesische Verkehrsminister Ignasius Jonan mit und berief sich dabei auf Radaraufzeichnungen. Der Steigflug sei dann plötzlich abgerissen. Vermutet wird, dass es zu einem Strömungsabriss gekommen sei. Dieser ist gefährlich, weil die Flügel den Korpus des Flugzeugs nicht mehr in der Luft halten können.

    In einer Parlamentsanhörung hatte Jonan zuvor ausgeführt, dass der Airbus A320 kurz vor dem Absturz um 1.800 Meter pro Minute aufgestiegen sei. "Ich denke, dass es selbst bei einem Kampfjet selten vorkommt, dass er 6.000 Fuß (1.800 Meter) pro Minuten steigt", sagte der Minister; bei einem Passagierflugzeug seien schon "1.000 bis 2.000" Fuß als außergewöhnlich anzusehen..................http://www.zeit.de/gesellschaft/zeitgeschehen/2015-01/airasia-absturz-ursache-indonesien

  2. Indonesia will not make public preliminary AirAsia crash report...

    Indonesia will not release to the public a 30-day preliminary report detailing its investigation into last month's crash of an AirAsia passenger jet that killed all 162 people on board, said Tatang Kurniadi, chairman of the National Transportation Safety Committee, on Wednesday.

    Investigators are expected to submit the preliminary report to the International Civil Aviation Organization (ICAO) early next week.

    Under ICAO regulations, the preliminary report must be filed within 30 days from the date of the accident.
