Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Avionics Technicians

Military experience isolating faults, inspecting systems, and removing, installing, and repairing integrated avionics directly overlaps civilian aircraft electronics maintenance.

How to prepare: Review the ASTM NCATT Aircraft Electronics Technician exam content and use it to identify subjects to study before testing.

What the civilian work involves
  • Test and troubleshoot instruments, components, and assemblies, using circuit testers, oscilloscopes, or voltmeters.
  • Adjust, repair, or replace malfunctioning components or assemblies, using hand tools or soldering irons.
  • Install electrical and electronic components, assemblies, and systems in aircraft, using hand tools, power tools, or soldering irons.

Training & Development

Choose credentials for your target role. COOL funding markers describe program listings, not a guarantee of eligibility or funding.

Getting Started

  • ASTM NCATT Aircraft Electronics Technician (AET)

    Demonstrate aircraft electronics knowledge through an exam-based credential aligned with civilian avionics work.

    Eligibility and preparation: No mandatory education, experience, or prior certification is required to take the exam.

    For: Avionics Technicians

  • ASTM NCATT Foreign Object Elimination (FOE)

    Build maintenance safety knowledge in tool accountability, housekeeping, and material handling.

    Eligibility and preparation: No mandatory education, experience, or prior credential is required; AET is not a prerequisite.

    For: Avionics Technicians
