What role does wing dihedral angle play in aircraft rigging?

The wing dihedral angle significantly contributes to the stability of an aircraft during flight. When wings are angled upward from the horizontal plane, this configuration enhances lateral stability. The design aids in maintaining level flight and helps the aircraft recover from roll disturbances. If an aircraft begins to roll to one side, the lowered wing generates more lift due to its increased angle of attack, which causes it to rise back to level flight. This inherent stability is crucial for safe and efficient operation, ensuring that the pilot can maintain control more easily under various flight conditions.

In contrast, while the other aspects mentioned—such as aesthetics, fuel capacity, and passenger comfort—may be relevant to overall aircraft design, they do not directly correlate with the functionality and performance benefits provided by the wing dihedral angle.
