The details of the pressure and airflow depend on the exact shape of the wing. However, there are general features that are true for any wing design. For example, wings are designed to be angled upward, to direct the airflow downward, and produce lift. The angle of the wing with the incoming air is known as the “angle of attack” and is a key concept in flight, controlling the amount of lift. Devices, like flaps, are also added to airplane wings to helps increase this angle of attack when landing or taking off.
To learn more about the details of the airflow around the wing, watch this video, or read this article. To understand more about devices used to create lift, see this article.
