If you fly into busy airports you probably keep an eye out for large airplanes. Whether a large aircraft is taking off or landing, it creates a hazardous stream of air that we call “Wake turbulence.” But why do we call it “Wake turbulence”?
A wake is the result of any body or object passing through a fluid such as air or water. If you have felt the air rush by a moving truck or have seen the waves created by a moving boat then you have seen a wake.
We use the world “turbulence” because the wake created by an airplane can be turbulent and potentially dangerous. In fact, wake turbulence has been a contributing factor in many fatal accidents. In 2001, an American Airlines A-300 lost control and crashed after encountering wake turbulence created by a Japan Airlines 747.
Communicating wake turbulence
Most of the time air traffic controllers will warn pilots of wake turbulence prior to taking off or landing. Here are a few audio samples of what you might expect to hear over the radio.
