The velocity at which yawing motion can be produced by rudder deflection while the aircraft is on the ground is called _______(a) Ground roll speed(b) Ground control speed(c) Minimum control speed on the ground(d) Control speed

Answer» The correct option is (c) Minimum control speed on the ground

For explanation I would say: Minimum control speed on the ground is the minimum speed at which enough aerodynamic force can be generated in the vertical fin by rudder deflection while the aircraft is still rolling on the ground to produce a yawing moment on the aircraft.
