CS 22.341 Gust load factors ED Decision 2003/13/RM (a) In the absence of a more rational analysis, the gust load factors must be computed as follows:  where:  = density of air at sea-level (kg/m3) U = gust velocity (m/s) V = equivalent air speed (m/s) a = slope of wing lift curve per radian m = mass of the sailplane (kg) G = acceleration due to gravity (m/s2) S = design wing area (m2) k = gust alleviation factor calculated from the following formula:  where:  (non-dimensional sailplane mass ratio) where: ρ = density of air (kg/m3) at the altitude considered 1m = mean geometric chord of wing (m) (b) The value of n calculated from the expression given above need not exceed:
