Developed by the Society of Automotive Engineers (SAE), the SAE ARP 1870 standard describes the minimum requirements for electrical bonding and grounding of electrical, avionics, weapons, communications and electronic equipment installations for aerospace applications. The bonding and grounding requirements specified in this standard are to ensure that a sufficiently low resistance return path is obtained for electrical, avionics, weapons, communications and electronic equipment that withstands operating conditions and corrosion. This is necessary for the following reasons:
A prerequisite for effective control of the hazards of electromagnetic interference (EMI) and electrical effects is: establishing a reference ground plane and providing adequate connections to it. Connecting to the ground plane is grounding. The mechanical method of providing low impedance unity between conductors is electrical bonding.
Grounding essentially refers to establishing an electrical connection with the ground. All electrical installations are connected to an object that enters the ground. Bonding, on the other hand, refers to connecting an electrical piece of equipment to the grounding system. Bonding equalizes the equipment's ground potential and eliminates static discharge between devices. In a successful grounding and bonding system, electromagnetic interference noise is carried to the ground through a shield that protects data from being affected by this noise during transmission. Everyone involved in wiring and bonding needs to understand both grounding and bonding. Furthermore, this system requires regular checks for the safety of aviation systems.
One of the most important factors in design and maintenance is the correct connection and grounding of aircraft electrical systems. Inadequate bonding or grounding can result in unsafe systems operation, such as electrostatic discharge damage to sensitive electronics, danger of personnel shock, or damage from a lightning strike.
