A Malaysia Airlines pilot successfully landed a passenger jet after it was caught in the wake turbulence of a larger aircraft in Malaysia on Sunday (December 15).

According to the Star, pilot Wee Cheng Yong felt the Boeing 737-800 plunge suddenly before swerving right and left about 10 minutes after he began preparing to land at Kuala Lumpur International Airport. However, he managed to regain control of the jet and landed safely at about 3:05 pm. It was later discovered that the air traffic control had failed to inform the pilot that the plane was flying in the vortex left behind by an Airbus A380.

All aircraft leave behind a vortex or wake turbulence. It is a rotating air disturbance created when the wings create lift. The high pressure air below the wing moves to the lower pressure zone above the wing. This creates a circulating air toward the tip and then forms vortices trailing from the tip. In fixed-wing aircraft, wake vortices begin during takeoff and continue throughout flight until the nose wheel touches down on the runway.

As the huge coils of rotating turbulent air are usually invisible. This poses a danger to any aircraft behind. Smaller planes usually needs to stay a minimum of two to three minutes away from larger aircraft, especially during landing and take-off to avoid wake turbulence.

This animation depicts the incident and explains how wake turbulence is generated.
