Qantas is conducting an internal review of a serious mid-air incident during which 15 passengers were injured when a jet's "stick-shaker" warning was activated.
Passengers on board flight QF29 from Melbourne to Hong Kong were about an hour from their destination when the drama unfolded last Friday, lasting about two minutes.
The airline said customers experienced "unexpected in-flight turbulence" on the Boeing 747.
"We notified the ATSB (Australian Transport Safety Bureau) of the occurrence, and our own teams are also reviewing the event," a spokeswoman said.
The ATSB said the flight crew had to disconnect the autopilot and manoeuvre the aircraft after the warning. It classified the incident as serious.
The "stick-shaker" warning is a device that causes the flight's control yoke to shake noisily and warn the pilot of an imminent stall.
According to Boeing it takes a physical, rather than visual, form so that crew members will be alerted even if they are not looking at the panel at the time.
