What would be the consequence of not grounding electrical equipment in an aircraft?

Not grounding electrical equipment in an aircraft can lead to static charge accumulation. Proper grounding is essential for safely dissipating static electricity that can build up on surfaces due to various factors like air friction and movement of parts. If equipment is not grounded, this static charge can interfere with sensitive electronic systems, potentially causing erratic behavior, malfunctions, or even system failures. It can also pose a significant risk of electrical shock to personnel working on or near the aircraft. Grounding helps ensure a safe and stable electrical environment, which is crucial for the optimal operation of avionics and other electrical components.
