Webb9 feb. 2024 · Being in ground effect has the added benefit of reducing the size of rotor the tip vortex produced by each blade as it travels through the air. Vortices produce a type of drag called Form Drag. Some say that Pressure drag and Form Drag is the same thing. While others say Vortex drag is its own type of drag different from the other two.

WebbGround Effect altitude is flying out of ground effect, but it’s downwash (induced drag) is a vector that is backwards, downwards, and (although we can’t see it) outward. As the airplane gets closer to the ground, this downwash is modified such that it contributes less of a vertical opposition to lift.
