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 the establishment of an electrical connection with grounding. The entire electrical installation is connected to an object that enters the ground. Bonding refers to the connection of an electrical equipment to the grounding system. By connecting, the ground potential of the equipment is equalized and static discharge between devices is eliminated. In a successful grounding and bonding system, electromagnetic interference noise is carried to ground through a shield that protects data from being affected by this noise during transmission. Anyone involved with wiring and connection needs to understand both grounding and bonding. At the same time, this system Regular checks of aviation systems should be made in terms of security.
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.
