The bonding straps installed in instrument mounts serve what purpose?

The bonding straps installed in instrument mounts are essential for providing a current path to ground. This grounding helps to eliminate static electricity build-up and prevents electrical interference from affecting sensitive avionics and instrumentation systems. By ensuring that there's a reliable pathway for electrical currents to dissipate safely, bonding straps contribute significantly to the overall safety and functionality of aircraft systems. They also help to maintain signal integrity, especially for instruments and systems that rely on accurate electrical readings and performance.

Other options, while potentially relevant to aircraft systems, do not directly relate to the specific function of bonding straps in this context. The primary role of bonding straps is to facilitate grounding, making it crucial for reducing electromagnetic interference and enhancing the reliability of avionics.
