What is dihedral in aviation terms?

Dihedral in aviation refers to the angle between the horizontal plane and the wings of an aircraft, particularly when the wingtips are higher than the wing root. This design provides increased lateral stability, allowing the aircraft to return to level flight more easily if it tilts to one side. The dihedral angle helps in maintaining controlled flight by counteracting the tendency of the plane to roll in response to turbulence or turns.

When the wings are positioned this way, the lift generated creates a righting moment, improving the aircraft's stability in flight. This design feature is commonly found in various aircraft types, from small general aviation planes to larger commercial aircraft, making it a fundamental aspect of aerodynamics and aircraft design.
