Calculating Headwind/Tailwind component
I think Ramy is correct in this. In his calculation he is basically
assuming that he is flying his true heading - that is, he has adjusted his
true course to compensate for wind. Because of this, all of the vectors
become co-linear.

To clarify more, my formula is not Wind =3D TAS-GS, it is HW component
=3D
=
TAS-GS. This is the true head wind component as I explained. XCSoar does
no=
t currently show the true head wind based on TAS-GS, instead it is
calculat=
ing it from the vector head wind which is not as accurate.=20
