computer: centre dot on TAS (240 kts), put heading 010°T under the HEADING index and mark a line down the
15° Stbd drift line. Rotate to put heading 085°T under the HEADING index and mark a line down the
10° Stbd drift line. The point where these two lines intersect is
the end of the wind vector; rotate to position it under the centre dot and read
the wind.
