What describes an anhedral wing configuration?

An anhedral wing configuration is characterized by a downward slope towards the wingtips. This design can be particularly advantageous in enhancing the aircraft's roll stability and maneuverability. By angling the wingtips downward, the anhedral wing can help lower the center of gravity of the aircraft and can improve how the wing interacts with the airflow, promoting better control during turns and maintaining a stable flight attitude.

In contrast, the other configurations described do not represent anhedral wings. A wing that is raised towards the tips would be classified as having a dihedral configuration, which is typically used to enhance lateral stability. Wings with upward sloping tips also fall into the dihedral category, contributing to positive directional stability. A completely horizontal wing, while it does not indicate either dihedral or anhedral, lacks the benefits that an anhedral design brings regarding roll responsiveness and maneuverability.
