They refer basically to requirements relating to the effect of lightning, return currents, One of the more im-portant factors in the design and maintenance of aircraft electrical systems is proper bonding and grounding. Grounding and Bonding Grounding is the electrical connecting of a conducting object to the primary structure to provide a return path for the electrical current. Wire specifications include MIL-W-7072 for aluminum wire and MIL-W-22759/1, /41, /16, /19, and /1044/9 for copper wire. Bonding also provides lightning protection by allowing the current to pass through the airframe with minimum arcing. The problems of making bonds and the often competing requirements of corrosion protection and low interface resistance are described. 5 milliohm requirement for lightning protection is derived by limiting the maximum voltage in the aircraft at 500 volts and defining the maximum current at 200,000 3. This AMC describes an acceptable means, but not the only means, for demonstrating compliance with the applicable certification specifications (CSs) related to high-intensity radiated fields (HIRF) protection (CS 23. It outlines standards for (2) Modify the electrical bonding of the main instrument panel (MIP) assembly located in front of and between the captain and first officer. It was decided to supplement the term “grounding” by adding “earthing” in the Airbus AMM relevant chapters dealing with the aircraft bonding/grounding (earthing) for all aircraft programs. Grounding provides an effective return path from loads to the power source MIL-B-5087B, MILITARY SPECIFICATION: BONDING, ELECTRICAL, AND LIGHTNING PROTECTION FOR AEROSPACE SYSTEMS (15-OCT-1964) [S/S BY MIL-STD-464].
