Today's flight was in wind from SE then NW then SW then SE then NW then SW then S then SW then SE then SW then NW. When approaching convergence lines the wind change was indicated on the Air-Glide S before the airmasses converged, by showing velocity reduction then change of direction then - on both mentioned varios - up indication.
