Which statement regarding wake turbulence is accurate?

The accurate statement regarding wake turbulence is that the primary hazard is loss of control due to induced roll. Wake turbulence occurs as a byproduct of lift generation, which creates rotating vortices behind an aircraft. These vortices can affect following aircraft, particularly smaller ones, leading to unexpected roll moments that can result in a loss of control.

When a larger aircraft generates lift, particularly at takeoff and landing, it produces these intense vortices that settle in a specific pattern behind the aircraft. Following aircraft operating in close proximity can encounter these vortices, resulting in an induced roll that can be difficult to manage. This is particularly critical during takeoff and landing phases, where precise control is essential.

The other statements are less accurate in their depiction of wake turbulence characteristics. For instance, vortex generation indeed begins during takeoff, but its immediate effects are most concerning post-flight as vortices remain for a period of time after the aircraft has departed. The greatest vortex strength typically occurs when an aircraft is heavy and clean, with some speed, but this is a condition rather than the primary hazard. Lastly, vortices do not dissipate immediately after landing; they can linger in the air for several minutes, posing a risk for any subsequent aircraft. Thus, the emphasis on
