Which type of aircraft produces wake turbulence?

Wake turbulence is a phenomenon generated by an aircraft as it passes through the air, creating vortices that can disturb other aircraft flying behind or near it. This turbulence is produced by the differences in pressure and the flow of air caused by an aircraft's wings.

All fixed-wing and rotary-wing aircraft produce wake turbulence, regardless of their size or type. This includes everything from light training aircraft to massive commercial airliners, as well as helicopters. The strength of the wake turbulence can vary based on the aircraft's weight, speed, and configuration but it is a characteristic of flight for all types of aircraft.

Understanding that all categories of aircraft contribute to this effect emphasizes the importance of maintaining safe distances during takeoff, landing, and flight operations. This knowledge is crucial for pilots to ensure safety, especially in busy airspaces. Thus, the correct answer correctly identifies that wake turbulence is a concern for every type of aircraft in operation.
