What is meant by 'rotation point' in regard to wake turbulence?

The rotation point refers specifically to the moment an aircraft begins its takeoff, which is where the pilot inputs the controls to lift the nose of the aircraft off the ground. This is crucial in understanding wake turbulence because it is at this point that an aircraft starts generating significant wake vortices, which can pose hazards to any following aircraft, especially during takeoff and immediate climb phases. Knowing the rotation point helps instructors ensure that students are aware of these generated vortices and the timing of their formation in relation to other traffic, especially in congested airport environments. Understanding this timing and the mechanics of wake turbulence is essential for ensuring safety in flight operations.
