It seems I can't get my head around this questions:
Your should follow a track due north taking account of a north westerly wind. You calculated a WCA –8°.
a) The drift will be 8° right
b) A track error of 2° (right) shows a drift of 10° right
c) A track error of –2° (left) shows a WCA of only –6°
d) The drift will be 8° left
answer: b)
The evaluation of your plotting work shows a WCA +3° and a drift 3° left
a) The track error is 6°
b) Your actual position is on the intended track
c) The expected W/V and the actual W/V coincide
d) The GS was exactly calculated
answer: b)
What is the difference between WCA and drift angle?
In the above questions I can`t explain myself why the other solutions are wrong.
Can anyone help me ? Thanks
