Then, starting from the lateral motion equation, the formulas of the minimum ground and air speed are deduced. Taking the H6 as an example, the calculation is made. The results show that the minimum ground and air handling speed depend on the yawing moment formed by working engine thrust. Finally, the factors that affect the minimum control speed are analyzed. The characteristics of the unsymmetrical thrust flight considering the minimum control speed are pointed out and can be used by pilots
