ALERT The noise of stalling alarm can be heard from the black box of AirAsia #QZ8501. More details:

Warning alarms in AirAsia flight QZ8501 were “screaming” as the pilots desperately tried to stabilise the plane just before it plunged into the Java Sea last month, a crash investigator said Wednesday (Jan 21).

The noise of several alarms – including one that indicated the plane was stalling – can be heard going off in recordings from the black box in the Airbus A320-200’s cockpit, the investigator told AFP, requesting anonymity.

“The warning alarms, we can say, were screaming, while in the background they (the pilot and co-pilot) were busy trying to recover,” the investigator said, adding the warnings were going off “for some time”.

The investigator, from Indonesia’s National Transportation Safety Committee (NTSC), added that the pilots’ voices were drowned out by the sound of the alarms.

The revelation came a day after Indonesian Transport Minister Ignasius Jonan said that the plane had climbed abnormally fast before stalling and plunging into the sea, during a flight on Dec 28 in stormy weather from Indonesia’s Surabaya to Singapore.

“In the final minutes, the plane climbed at a speed which was beyond normal,” the minister told reporters. The plane crashed in shallow waters with 162 people on board, but so far just 53 bodies have been recovered.
