What should the electrical resistance of bonding jumpers be no more than?

The correct electrical resistance for bonding jumpers should be no more than 0.003 ohms. This low resistance value is critical in aircraft avionics systems to ensure efficient electrical bonding and grounding of aircraft components. Low resistance in bonding jumpers minimizes the risk of voltage differentials between various parts of the aircraft, which can lead to interference with electronic systems, reduce the likelihood of damage from static discharge, and maintain the overall safety and reliability of the electrical system.

In aviation, ensuring that these resistances are kept to a minimum is paramount because any increase in resistance can impair the performance of electrical components and systems, affecting everything from communications to navigation and safety systems. Therefore, maintaining bonding jumpers at or below this specified resistance level is essential to uphold the integrity of the aircraft’s avionics systems.
