What is the purpose of the rigging chart in assembly?

The rigging chart plays a crucial role in ensuring the proper setup and alignment of the aircraft's control surfaces, which is vital for safe and efficient flight operation. This chart provides definitive specifications and adjustments for each control surface, detailing how they should be positioned relative to the aircraft’s structure.

A precise alignment is necessary because even small deviations can lead to issues with aircraft performance, stability, and control. Proper rigging ensures that control surfaces such as ailerons, elevators, and rudders respond accurately to pilot inputs, making the rigging chart an essential reference during assembly and maintenance processes.

The other options, while related to aspects of aircraft assembly and operation, do not accurately describe the primary function of the rigging chart.
