What is the wind direction and speed with a true course of 345° and true heading of 355°?

To determine the wind direction and speed, the difference between the true heading and the true course should be assessed. The true course is the intended path of flight over the ground, while the true heading is the direction the aircraft is pointed, which takes into account the wind's impact.

In this scenario, the true course is 345° and the true heading is 355°. The difference between the two is 10° (355° - 345°). Since the true heading is greater than the true course, it indicates that the wind is coming from the left of the aircraft's path, which means the wind is from the southeast.

To find the wind direction, one needs to convert this relative wind vector into an absolute wind direction. Since the heading is affected by the wind from the left, you would add 90° to the left side of the true course (which is counter-clockwise). Therefore, when you subtract the 10° from 355°, the resultant wind direction of 345° - 90° = 255° (wind from the south quadrant) does not seem to match the provided options directly.

However, recognizing that the wind correction angle (the deviation caused by the wind on heading) should express itself in terms
