To avoid wake turbulence from a large jet aircraft before takeoff, a pilot should plan to become airborne when?

The correct choice indicates that a pilot should plan to become airborne past the point where the jet touched down to ensure safety from wake turbulence. Wake turbulence is a significant factor that can affect trailing aircraft, especially during takeoff and landing phases, as it is generated by the departing and arriving aircraft.

When a large jet aircraft lands, it produces vortices that linger and descend slowly to the ground. These vortices can be particularly hazardous to smaller aircraft, especially when they are close to the ground during takeoff. By waiting to take off past the point where the large jet has touched down, the trailing aircraft allows enough time for these vortices to settle, thereby reducing the risk of encountering them during its climb out.

Choosing to become airborne at the point where the jet touched down, just prior to that point, or before the jet executes its landing does not provide sufficient distance from the wake turbulence that may still be present in the flight path. Such timing could place the aircraft directly in the path of potentially hazardous turbulence, which could lead to loss of control or other safety issues. Therefore, deciding to take off after the jet's touchdown point is the best strategy for avoiding wake turbulence.
