Quite interresting. To go back to the original question; If I fly exactly Vref over the threshold, as determend in the AFM, any windcomponent should not affect my stallspeed margin. Wind only changes my groundspeed over the runway. If I do not ad an extra couple of knots to my Vref, my groundspeed would be less (with an headwind component), so decreasing my landingroll. Now I can understand adding a HWC in gusts for safety margins on my Vref, but to always add a HWC to my Vref still keeps me questioning this procedure (although I have to use it as well). Please, can anyone comment on this one?
