If a true heading of 135 results in a ground track of 130, the wind would be from...

To understand why the correct answer is 246 degrees for the wind direction, we need to analyze how wind affects the aircraft's heading and ground track.

When an aircraft is flying with a true heading of 135 degrees but is tracking along a ground track of 130 degrees, it indicates that the wind is pushing the aircraft sideways. The difference between the true heading and the ground track is often referred to as the "drift." Since the aircraft is heading slightly to the right (more southeast) than it is tracking, the wind must be coming from a direction that would cause that drift.

The drift angle can be calculated by taking the true heading and the ground track; in this case, the difference is 5 degrees (135 – 130 = 5 degrees). This drift suggests that the wind is coming from a direction that is 5 degrees towards the left from the true heading of 135 degrees.

To determine the wind direction, we can analyze the heading of the aircraft. A true heading of 135 degrees indicates the aircraft is pointing towards the southeast. If the wind is causing it to track 5 degrees to the left, we can visualize this shift on a compass, which means that the wind is coming more from the west-south
