''Wind direction'' and ''speed'' define ''the lowest aloft wind'' in a height convenient to the atmospheric boundary layer thickness. If "terrain presampling" is disabled, the boundary layer thickness is 600 feet above ground level. The definition of the "wind direction" and "speed" has no effect in METAR tile mode (because AW deduces it from the METAR itself, which reports the ''ground'' wind) and/or when the wind model is ''aloft interpolated'' or ''aloft waypoint'' (because that wind is used instead - see below). Otherwise you can use it. | ''Wind direction'' and ''speed'' define ''the lowest aloft wind'' in a height convenient to the atmospheric boundary layer thickness.

''Gust settings'' are the happiest ones: they always work, immediately, no click needed, but if a new live METAR comes in (because you moved to a new area) they'll be overwritten. Their meaning should be self-explanatory. Note that gusts are only effective in the boundary layer, i.e. when close enough to the ground. | ''Gust settings'' are the happiest ones: they always work, immediately, no click needed, but if a new live METAR comes in (because you moved to a new area) they'll be overwritten.
