Top-down view with north at the top. A drone sets out to fly a desired track of 090 degrees (due east, dashed line). With heading 090 and a wind from 360 (the north), the wind pushes the drone sideways, so its track over the ground is to the right of its heading, south of the desired track. Heading (blue, where the nose points), wind (red), track (green, the path over the ground) and the drift angle between heading and track (orange) appear in turn. With heading corrected, the nose points slightly into wind, about 080 in this example, and the track stays on 090. Example values, not to scale.
