What is the primary purpose of bonding in aircraft?

The primary purpose of bonding in aircraft is to ensure the same electrical potential of all metal components. This is crucial for the safety and functionality of the aircraft's electrical systems. When all metal components are at the same electrical potential, it minimizes the risk of electrical shocks and damage caused by voltage differences. This uniformity helps to prevent interference with sensitive electronic equipment and reduces the likelihood of stray currents causing malfunctions.

In aviation, bonding is particularly important as it helps to protect against potential hazards such as lightning strikes and electromagnetic interference. If different components were to have varying potentials, it could lead to harmful situations, including the risk of sparks or electrical arcs, which could compromise aircraft safety.

This understanding of bonding emphasizes the necessity for electrical continuity between metallic surfaces, aiding in the prevention of corrosion and ensuring the reliability of system performance. Proper bonding also plays a role in mitigating the effects of static electricity, contributing to overall aircraft safety and operational integrity.
