Key electrical tests in the aviation industry

The aviation industry sets high standards for the reliability and safety of aircraft. A key part of this is the thorough testing of the aircraft’s electrical systems.

These systems are critical to the operation of navigation, communication, engines, and many other functions. In this article, we discuss the main electrical tests performed to ensure that these systems function optimally.

Common tests relate to item 1, Functional testing of electrical systems. Item 4 covers, among other things, checking electrical safety and functionality.

  1. Functional testing of electrical systems
  2. Continuity testing
  3. Wiring Harness Testing
  4. Electrical Safety & Compliance Testing
  5. Insulation Resistance Testing
  6. High-voltage testing (HiPot)
  7. Grounding Tests

The tests mentioned are often part of the applicable norms and standards listed below;

  • Airbus ABD0100.1.8 (A380)
  • Airbus ABD0100.1.8.1 (A350)
  • Airbus AMD24C (A400M)
  • Boeing 787B3-0147 (787)
  • RTCA/DO-160, Section 16
  • MIL-STD 704
  • MIL-STD 1399-300, Rev B & Part 1

Recommended test equipment for avionics-related applications:

  1. AC power supplies
  2. 270 VDC in the avionics.
  3. Simulation software
  4. Electrical Safety & Compliance Testing
