The 50/150 wind component requirement appears in the design standards. As such it should be built into the AFM charts.
How do you tell ?
Have a look at the chart (if the AFM present data in tabular format you may have to draw a quick sketch to see the effect described below) -
Subject to how the OEM has put the equations together,
(a) if there is a discontinuity (ie the slope of a line changes noticeably) at zero wind, then the factors are included. This may be a little difficult to see at the lower weight/distance end of the wind carpet but will be quite obvious at the other end.
(b) if there is no discontinuity and the wind line is nice and smooth across zero, then it is not.
