What factors can affect the rigging of an aircraft's wings?

The correct answer, which involves wing twist, dihedral angle, and structural integrity, encompasses critical aspects that influence the rigging of an aircraft's wings.

Wing twist refers to the angle change along the length of the wing, which can affect lift distribution and stall characteristics. Proper rigging must account for any twist to ensure optimal aerodynamic performance.

The dihedral angle, which is the upward angle of the wings relative to the horizontal plane, affects an aircraft's roll stability. Ensuring the proper dihedral angle is vital for maintaining control during flight; hence, accurate rigging is necessary during assembly.

Structural integrity plays a fundamental role in wing rigging. This includes ensuring that all components are securely attached, and that the wing can withstand the aerodynamic forces it will encounter in flight. Any weakness in the wing structure could lead to operational failures, making it essential for proper rigging to uphold the aircraft's safety and performance.

The other options do not capture the critical technical aspects that can significantly impact wing rigging, making them less relevant for this question.
