  1. Safety Ohmmeter C003.02.03/ 16

  2. Objective You will be able to demonstrate an understanding of Avionic circuit testing with regards to the safety ohmmeter. C003.02.03/ 16

  4. Bonding Testing Bonding means ‘to tie’, ‘connect’, ‘join together’ or to ‘form a single unit’ C003.02.03/ 17

  5. Safety Ohmmeter Pre-Use Checks C003.02.03/ 18

  6. Earthing & Bonding The metal airframe is used as the ‘negative return path’ for aircraft electrical circuits. ON OFF Battery Aircraft structure Aircraft structure C003.02.03/ 17

  7. Earth Points C003.02.03/ 17

  8. Objective You will be able to demonstrate an understanding of Avionic circuit testing with regards to the safety ohmmeter. C003.02.03/ 16

  9. Summary What do we mean by the term bonding in terms on aircraft electrical systems? It is the interconnection of conducting parts of an aircraft to ensure the safe distribution of electrical charges and currents.

  10. Summary What electrical quantity does a Safety Ohmmeter measure? Resistance – (primarily very low resistance). What are the two functions of the Safety Ohmmeter? Perform aircraft electrical bonding checks Perform resistance checks on sensitive electronic circuitry

  11. Summary The Airframe should form a Low Resistance path to allow it to: Be safely used as an “earth return system” under normal and fault conditions. Ensure that electro static charges cannot build up between adjacent panels. Minimize the damage to the aircraft structure and components in the event of a lightning strike.
