§23.455 Ailerons.

(a) The ailerons must be designed for the loads to which they are subjected-- (1) In the neutral position during symmetrical flight conditions; and (2) By the following deflections (except as limited by pilot effort), during unsymmetrical flight conditions: (i) Sudden maximum displacement of the aileron control at VA. Suitable allowance may be made for control system deflections. (ii) Sufficient deflection at VC, where VC is more than VA, to produce a rate of roll not less than obtained in paragraph (a)(2)(i) of this section. (iii) Sufficient deflection at VD to produce a rate of roll not less than one-third of that obtained in paragraph (a)(2)(i) of this section. [(b) [Reserved.]]
