    Re: Wind Velocity from Three Drifts

    Thank you all for the replies!

    Dear David, I'm asking not only about being late to the DR point because of the extra time spent to fly longer track while determining the wind vector.

    Let me give an (unrealistic) example: consider a wind with a velosity equal to our TAS, then on one of the legs (if it happens to be 0° against the wind) we will have our GS == 0. So the second leg will take us significantly leeways from our initial track.

    The +60°|-120° veering will make us late by the time spent on doing those legs, that's easy to account for.

    Should we also account for being leeways after the wind vector determination? That is my question.

    Warm regards,
    60°N 30°E
