If a true heading of 135° results in a ground track of 130° and a true airspeed of 135 knots results in a groundspeed of 140 knots, the wind would be from
A
019° and 12 knots.
B
200° and 13 knots.
C
246° and 13 knots.✓ Correct Answer
Explanation
The wind is the difference between the ground vector (140 knots toward 130 degrees) and the air vector (135 knots toward 135 degrees). Resolving them gives a wind vector of about 13 knots blowing toward 065 degrees, that is, from about 245 degrees. That fits the picture: the track drifts left of the heading and groundspeed exceeds airspeed, so the wind comes from behind on the right.
