"With the A380 vs Challenger 604 incident, there is now growing concern amongst aircrews about the effects of the A380's wake turbulence," the Flight Service Bureau, an information source for air operators, told Travel Weekly.
The A380 continued to Sydney and landed safely, however the smaller jet was forced to make an emergency landing in Muscat.
The German Federal Bureau of Aircraft Accident Investigation is leading the enquiry into the incident, which is believed to have occurred on January 7.
Wake turbulence is formed behind an aircraft as it flies through the air, much like a boat creates a wake in the water, reports the Daily Mail.
It is exacerbated by a pair of vortices - whirling masses of air - that spin from the wingtips. The vortices are mostly created when a plane is flying slow and the wings are working hardest to produce lift.
The bigger the plane, the bigger the wakes. The most virulent wakes leave smaller planes vulnerable if they run into one.
It cannot be seen by pilots or be detected on their radar and can linger in the air for several minutes.
