OK, very good... That's comply technical way that down force on elevator adds load to the wings which require higher airspeed at constant AOA. However Lift and CP are not constant with respect to AOA.

Forgive me if I'm getting farther from the subject but just wanna clear that there are two alternative solution on this topic at this time. By taking differential lift from moving CG or by increasing downward force using our solution to find out which is more effective.

This is why we need to raise the nose up on landing to slows down. When AOA increases center of pressure (CP) moves forward up to higher coefficient. CG must not go after the CP otherwise the plane will be able to land. This is why a non-nose heavy aircraft require to nose down to compensate for CP change. Maintaining CP after CG will make the plane able to descend smoother. At higher AOA the plane will benefits from lower speed, at nose heavy a plane will benefit from higher stability. Most likely the plane lands above stall level but lower in speed.

The force and moment torque generated at the tail which contributed to airspeed and wing loading is almost negligible at higher AOA.

On the other side using spoilerons, spoilers, crow has plenty of effect to the lift reduction due to wing camber and CL and this is proven effective for light aircraft or even to high performance aircraft which require smooth descend. However flaps, flaperons are proven effective to high wing loading aircraft to slows down and shorten the landings.
