wildbill,as teeters says,do an `airplot `on some graph paper; you should find that,your ground speed is 97 kts,your drift is 3.5 deg. port,as you are left of track,and computing gives a wind of 260/7kts appx. So ,if you are going 100 miles,you need to alter heading 3.5d stbd,to parallel track,then another 3.5 d to regain track at destination,or, 10.5 d stbd to regain track at about the 75 mile mark.Suggest another 50 rpm and you will regain time as well,as you are 1minute late.....
Whilst the `radio beacon may still be showing 200deg. it is probably a class B bearing which was accurate to about +- 5 deg.Dont forget your fuel checks and time log.....
