Angle of attack (AOA) refers to the angle between the wing's chord line and the direction of the relative wind. This angle is crucial for understanding how lift is generated by the wings of an aircraft. When an aircraft is in flight, the relative wind is created by the aircraft's forward motion through the air. By measuring the AOA, pilots can assess how much lift is being generated and whether they are approaching critical lift limits, which could result in stalling if exceeded. Understanding AOA is essential for effective flight maneuvering and maintaining safe flight conditions.

The other options do not accurately define angle of attack. The angle determining aircraft pitch refers to the aircraft's orientation rather than the relationship between the wing and wind flow. Wind speed is measured using different parameters and is not related to the geometry of the wing in relation to airflow. The angle of descent during landing refers to the glide path of the aircraft and is not related to AOA, which specifically deals with the wing's position concerning the oncoming air.
