How does the weight of an aircraft influence its wake turbulence?

The weight of an aircraft significantly affects the strength of the wake turbulence it generates. Heavier aircraft create stronger vortices due to the higher mass and lift forces involved in their flight. When an aircraft generates lift, it pushes air downwards, creating a rotational flow behind it known as wake turbulence. The intensity of this turbulence increases with the weight of the aircraft because a heavier aircraft displaces more air to generate the necessary lift for its operations.

The vortices produced by heavier planes, such as large commercial airliners or cargo aircraft, rotate more vigorously and persist longer in the atmosphere compared to those produced by lighter aircraft. This wake turbulence poses risks to following aircraft, particularly smaller ones that may be more susceptible to these stronger vortices. Understanding this relationship is crucial for air traffic controllers when managing the separation between different types of aircraft to ensure safe operations and minimize turbulence-related incidents.

In contrast to the selected answer, lighter aircraft do not produce as strong of vortices, and the weight of an aircraft directly correlates with the strength of wake turbulence, making the choice about weight's influence on turbulence essential for safe air traffic management.
