What does the term "rigging" refer to in the context of aircraft systems?

The term "rigging" in the context of aircraft systems specifically refers to the process of securing and adjusting components, cables, and control surfaces to ensure they operate correctly and safely. Proper rigging is crucial for the functionality of the aircraft's flight control system, as it ensures that all associated mechanisms, such as flaps, ailerons, and rudders, move as intended. This involves fine-tuning cable tension, alignment, and travel limits, all of which are vital to achieving optimal handling characteristics and adherence to safety standards.

Other options, while related to aircraft maintenance and functionality, do not accurately represent the definition of rigging. Installing decorative elements does not affect the aircraft's operational capabilities, adjusting fuel levels pertain to fuel management rather than rigging, and inflating tires relates specifically to landing gear maintenance, which falls outside the scope of rigging.
