CS 22.443  Gust loads

ED Decision 2003/13/RM

(a)     Vertical tail surfaces must be designed to withstand lateral gusts to the values described in CS 22.333(c).

(b)     In the absence of a more rational analysis, the gust load must be computed as follows:

where:

  =  gust load (N)

 = slope of vertical tail lift curve per radian

  = area of vertical tail (m2)

 = density of air at sea-level (kg/m3)

V    = speed of flight (m/s)

U    = gust speed (m/s)

K    = gust factor, should be taken as 1.2
