The ATSB is investigating after a rare “stick shaker” warning activated during a flight from Melbourne.

15 out of a potential 400 hurt, in seven seconds – a bloody miracle.
Well done Big Q crew; good catch, nice recovery. Bravo.
A’yup, it’s a numbers game alright.
A380 wake turbulence - hmm maybe related..
There seems to be a growing trend of A380 wake turbulence incidents, via the Oz today:

CASA says Australia already has a range of wake turbulence measures in place.Australia’s aviation safety watchdog is considering issuing extra advice on dangerous wake turbulence amid fresh warnings the phenomenon is on the rise as air traffic grows.

The Australian has confirmed that the Civil Aviation Safety Authority is looking at issuing advice after the European Aviation Safety Agency published safety information on mitigating the dangers of midair wake vortex encounters.
A CASA spokesman said that Australia already had a range of wake turbulence measures in place but added: “Beyond the existing measures, CASA will consider similar advisory advice with the additional information contained in the EASA guidance.”
Earlier this year there were concerns wake turbulence was possibly implicated in the April “stick shaker” stall alert on a Qantas Boeing 747 flight from Melbourne to Hong Kong and in the dramatic roll of a Learjet over Oman in January.
The Learjet, a Bombardier Challenger 64, was written off by insurers after a midair roll and 10,000-feet drop after it passed under an Airbus A380 going in the opposite direction.
While there are reports that the European move was not spurred directly by that incident, the advice is aimed at pilots and air traffic controllers.
“With the increase of the overall volume of air traffic and enhanced navigation precision, wake turbulence encounters in the en-route phase of flight above 10,000 feet ... have progressively become more frequent in the last few years,” the EASA bulletin says. It warns that minimum separation criteria “will not completely prevent wake encounters from occurring”.
As well as causing the aircraft to roll, wake turbulence can cause vertical acceleration and significant altitude changes.
“The greatest danger is typically the induced roll that can lead to a loss of control and possible injuries to cabin crew and passengers,” the bulletin says.
CASA’s spokesman said that for departure and arrival here, air traffic control applies specific time or distance spacing between aircraft of different weight categories based on the International Civil Aviation Organisation standards.
Also in line with ICAO recommendations, Australian air traffic control “applies extra time and distance spacing between Airbus A380 aircraft and aircraft that follow behind”.
“Beyond ICAO standards and recommended practices, Australian ATC applies extra distance spacing between aircraft in the en-route environment to account for wake turbulence,” the CASA spokesman said.
“The distance spacing required in Australia for the en-route environment is generally the same and in some cases greater than is required in similar circumstances in the airspace over the United States or the United Kingdom.”
Australia requires pilots of planes in the heavy wake turbulence category or the Airbus A380 to add the designation “heavy” or “super” after their aircraft call sign in initial radio communication with air traffic control.
A spokeswoman for Airservices Australia said the rules were under constant review.
“Safety is Airservices number one priority, and we consistently review the rule set used by our controllers which includes procedures on wake turbulence,” the spokeswoman said.
“It is Australian practice, to provide air traffic advice when aircraft are passing with the minimum vertical standard. Our controllers will accommodate offsets if requested.”
In Oceanic airspace, pilots are able to strategically offset horizontally from their route for up to two nautical miles without seeking permission.
“Airservices will continue to follow and work under the direction of the International Civil Aviation Organisation and the Civil Aviation Safety Authority.”
The new EASA bulletin gives advice to pilots, including a warning that disconnecting autopilot in the case of a wake encounter “can complicate the scenario” and the autopilot will “in most cases, facilitate the recovery”.
