What Is the Difference Between Anhedral and Dihedral?

Dihedral is where the wing slopes in a positive (upward) degree in relation to the wing base, whereas anhedral wings have a negative (downward) slope from the wing base. ... The main desirable effect this wing configuration has is its effect on roll stability.

What do Anhedral wings do?

Anhedral wings will induce roll instability and improve roll maneuverability. In a large/heavy airplane with a high-wing configuration there is usually excess roll stability, so this type of wings can be pretty common.

What is a Anhedral?

: the angle between a downwardly inclined aircraft wing and a horizontal transverse line The bottom wing had pronounced anhedral; the upper wing, dihedral.—
