CS-VLA 335 Design airspeeds ED Decision 2003/18/RM Except as provided in sub-paragraph (a)(4) of this paragraph, the selected design airspeeds are equivalent airspeeds (EAS). (a) *Design cruising speed, VC*. For VC the following apply: (1) VC (in m/s) may not be less than - 2·4  (VC (kt) = 4·7  ) where - M/S = wing loading (kg/m2) g = acceleration due to gravity (m/s2) (2) VC need not be more than 0·9 VH at sea level. (b) *Design dive speed VD*. For VD, the following apply: (1) VD may not be less than 1·25 VC; and (2) With VC min, the required minimum design cruising speed, VD may not be less than 1·40 VCmin. (c) *Design manoeuvring speed VA*. For VA, the following applies: (1) VA may not be less than VS  , where - (i) VS is a computed stalling speed with flaps retracted at the design weight, normally based on the maximum aeroplane normal force coefficients, CNA; and (ii) n is the limit manoeuvring load factor used in design. (2) The value of VA need not exceed the value of VC used in design
