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
