<WBR>The 010 track<br>
is caused not by a weathervane effect, but by the body of air moving from<br>
west to east while airplane progresses<br>
through it on north heading.<br>
<br>
<br>
<br>
During this flight, (and in<br>
Case 1 and 2) a yaw string would be straight, no wind hits side of airplane.<br>
<br>
<br>
<br>
I'm missing something here. The body of air moving from west to east is <br>
not hitting the airplane? Then what makes it go off course? Please explain.<br>
