What information is necessary to utilize a cable rigging chart?

To effectively utilize a cable rigging chart, it is essential to know the cable size and ambient temperature. The cable size is critical because it determines the specific rigging tolerances, tensions, and adjustments necessary to ensure that the aircraft operates safely and efficiently. Ambient temperature is equally important, as it can affect the properties of the cable; for instance, changes in temperature can influence the cable's tension and stretching capabilities.

In situations where these factors are not taken into account, there could be significant safety risks during flight operations, including potential failures in control surfaces or other critical systems that depend on correct cable tension and configuration.

The other choices, while potentially informative in other contexts, do not provide the necessary information needed to effectively use a cable rigging chart.
