Micro Vortex Generators (VGs) are placed in a spanwise line two to fifteen percent aft of the leading edge of the wing. 

They control airflow over the upper surface of the wing and the tail surfaces by creating vortices that energize the boundary layer. 

This results in improved performance and control authority at low airspeeds up to the critical angle of attack.

A Micro Vortex Generator creates a tiny vortex in the airstream over an airfoil. This vortex energizes the normally stagnant boundary layer of air on the wing and tail surfaces. 

An energized boundary layer is more resistant to flow separation than a stagnant boundary layer. 

The result is that airflow “sticks” to the wing and control surfaces better, providing greater lift, which results in greater control in flight at slower airspeeds such as take-off and landing.
