How is the term "wake turbulence" defined?

• A. Disrupted airflow created by an aircraft, which can affect following aircraft during takeoff and landing.
• B. Airflow created by the engine of an aircraft during cruise.
• C. Normal airflow experienced by all aircraft in flight.
• D. Specific turbulence experienced only during thunderstorms.

Answer: (A)

Wake turbulence is specifically defined as the disrupted airflow created by an aircraft, particularly during phases of flight such as takeoff and landing. When an aircraft flies, it generates vortices - swirling air currents that trail behind its wingtips. These vortices can pose a significant hazard to following aircraft, especially smaller ones, as they can lead to loss of control or sudden changes in altitude if encountered unexpectedly. Understanding wake turbulence is crucial for air traffic controllers and pilots, as proper spacing between aircraft during takeoff and landing operations is essential for safety. This knowledge helps in preventing accidents or incidents resulting from the effects of wake turbulence on trailing aircraft.
