23.455—Ailerons.
        
        (2) 
         By the following deflections (except as limited by pilot effort), during unsymmetrical flight conditions:
    
    
        
        (i) 
         Sudden maximum displacement of the aileron control at V
            A. Suitable allowance may be made for control system deflections.
    
    
        
        (ii) 
         Sufficient deflection at V
            C, where V
            C is more than V
            A, to produce a rate of roll not less than obtained in paragraph (a)(2)(i) of this section.
    
    
        
        (iii) 
         Sufficient deflection at V
            D to produce a rate of roll not less than one-third of that obtained in paragraph (a)(2)(i) of this section.
