What is the classification weight for a heavy wake turbulence category?

The classification weight for a heavy wake turbulence category is indeed set at 300,000 lbs or more. This classification is essential for understanding the effects of wake turbulence generated by large aircraft. Aircraft that fall within this weight category, such as large commercial airliners and heavy cargo aircraft, create significant wake vortices that can affect smaller aircraft following them.

Understanding this classification helps pilots and air traffic controllers maintain safe distances between aircraft, particularly during takeoff and landing phases. The determination of these categories is based on the aircraft's maximum certified takeoff weight, which is critical for safety procedures surrounding wake turbulence avoidance.

Other options represent different weight classifications that do not align with the established heavy category, making them unsuitable for understanding heavy wake turbulence impacts.
