What is meant by the term "Wake Turbulence"?

• A. Airborne emissions from an aircraft
• B. The disturbance in the air caused by the passage of an aircraft
• C. An indication of a procedural error
• D. A specific weather phenomenon affecting flight

Answer: (B)

The term "Wake Turbulence" refers specifically to the disturbances in the air that occur as a result of an aircraft's movement through the atmosphere. When an aircraft flies, it disrupts the airflow around it, creating vortices that trail behind. These vortices can be particularly strong, especially with larger aircraft, and can pose significant hazards to following aircraft, especially smaller ones. Understanding wake turbulence is crucial for air traffic controllers and pilots to ensure safe separation between aircraft, particularly during takeoff, landing, and when operating in close proximity. Awareness of wake turbulence helps in preventing accidents and ensuring that procedures for departing and arriving aircraft effectively account for these disturbances.
