Which term describes a downward slant from root to tip of a wing?

• A. Anhedral
• B. Dihedral
• C. Cant
• D. Sweep

Answer: (A)

Anhedral describes a wing that slopes downward from the root to the tip. This downward angle reduces the dihedral effect, making the aircraft less laterally stable in a sideslip and more prone to roll, which can be desirable for certain designs that need quicker roll response or have stability provided by other features.

Dihedral, the opposite term, is when the wings slope upward from root to tip, increasing lateral stability. Sweep refers to the wing’s leading edge angle relative to the fuselage and relates to aerodynamic characteristics rather than the vertical slope of the wing. Cant isn’t the standard term for describing the spanwise slope from root to tip in this context.
