What weight range defines a Large Aircraft in terms of wake turbulence?

The classification of a Large Aircraft in terms of wake turbulence is determined by its maximum takeoff weight. A Large Aircraft is defined as one that weighs between 41,000 lbs and 300,000 lbs. This classification is important for air traffic control and safety measures, as larger aircraft generate more significant wake turbulence, which can affect the performance and safety of following aircraft. Understanding this classification helps in establishing appropriate separation distances during takeoff, approach, and landing to ensure safety in operations at airports. The range of 41,000 lbs to 300,000 lbs encompasses a variety of commercial jets, business jets, and some cargo aircraft that fall under this category and is critical in establishing proper operational protocols in relation to wake turbulence.
