Since I don't control the airplane, in a contact environment, by reference to instruments, I am not a big V speed fan. With the FAA's recently greater interest in loss of control mitigation, perhaps a new one might point us in the direction of mitigation.
No!, let's just go back to rudder and stick basics. In real slow flight, with the stall warning horn on, we learn very quickly why rudder is a primary control and aileron is a secondary control. Because it is mounted on the center of the longitudinal axis and because it gets more prop blast and because it doesn't have adverse yaw problems, rudder will maintain wings level and directional control at much slower airspeed than will aileron.
Most of us who taught before integration of instrument control technique believe that rudder control should be emphasised in slow flight at altitude and especially when we are trying to slow to Vsige (Velocity stall in ground effect) to land safely and at a speed less likely to cause damage. Sorry, I guess that V speed isn't in the book either. We believe rudder leads aileron in coordinated turns and that there are many places where only rudder mitigates loss of control problems.
