What is the purpose of electrical bonding jumpers in aircraft?

The primary purpose of electrical bonding jumpers in aircraft is to decrease the probability of lightning damage and reduce radio interference. These jumpers create a continuous electrical connection between various components of the aircraft's structure. By ensuring that all parts are properly bonded, they facilitate the equal distribution of electrical charges during a lightning strike, which mitigates the potential for damage to sensitive electronic systems and the airframe itself.

Additionally, effective bonding reduces electromagnetic interference, which can disrupt avionics and communication systems. Therefore, the installation of electrical bonding jumpers is crucial for maintaining the operational integrity and safety of the aircraft, particularly in terms of its electronic systems and overall resilience to environmental electrical phenomena.
