200° radial inbound = Track 020°M, Variation +5° (E) = 025°T

                                                                        Heading            = 010°T

                                                                        Drift                   = 15° Stbd

 

090° radial outbound = Track 090°M, Variation +5°(E)  = 095°T

                                    Heading 080°M, Variation +5°(E)     = 085°T

                                                                        Drift                      = 10° Stbd

 

Nav 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.
