Study Notes

Electrical & Electronic Equipment Installation

  • All electrical and electronic components must be installed to ensure a continuous low resistance path, known as bonds, from the equipment enclosure or component to the aircraft structure.
  • These bonds are crucial for maintaining electrical stability and preventing hazards such as lightning strikes, static discharge, and electrical shock.
  • The primary objective of bonds is to create a continuous pathway for electrical current to flow safely through the aircraft structure, preventing potential damage to the equipment or harm to passengers and crew.
  • This ensures safe operation and protects against the risk of electrical malfunction or failure in the event of an electrical surge.
  • By establishing a continuous low resistance path, the bonds effectively ground the equipment and the aircraft structure, preventing the build-up of static electricity and mitigating the effects of lightning strikes.
  • This grounding mechanism prevents the accumulation of electrical charges on the aircraft surface, minimizing the risk of electric shock and ensuring the safe dissipation of electrical energy.
  • The importance of proper bonding practices cannot be overstated, playing a vital role in ensuring the safety and reliability of aircraft electrical systems.
