A design feature where the wingtips are lower than the wing roots. Engineers use this downward slope primarily on high-wing transport aircraft and swept-wing fighters to reduce inherent roll stability, making the aircraft more maneuverable and responsive to control inputs.
Heard on the job
The massive cargo jet uses a pronounced anhedral to prevent it from being too stable and sluggish in the roll axis.
Do not mix it up with
- Dihedral: Dihedral is an upward wing angle for stability, while anhedral is a downward angle for maneuverability.
