Which situation contributes to an increased likelihood of experiencing wake turbulence?

The situation of departing immediately after a heavy jet significantly increases the likelihood of experiencing wake turbulence. This phenomenon occurs because heavier aircraft generate stronger vortices, especially during takeoff and landing, due to their larger wingspans and greater lift requirements. When a heavy jet takes off, it creates wake vortices that descend and drift laterally from the aircraft. If another aircraft takes off shortly after, it risks encountering these turbulent air masses, particularly if it is not well separated in time and distance from the departing heavy jet.

In contrast, taking off behind a small aircraft does not present a similar risk, as smaller planes produce significantly weaker wake turbulence due to their lighter weight and smaller wings. Poor weather does not inherently increase the generation of wake turbulence, although it may impact visibility and judgment. Landing first at an airport typically does not pose a wake turbulence hazard since the aircraft is on the ground and not producing any significant turbulent air. Thus, departing immediately after a heavy jet is the most critical scenario concerning wake turbulence risk, emphasizing the need for proper spacing and awareness of preceding traffic.
