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

Intermediate-level testing and repair of airborne communications, navigation, cryptographic, and countermeasures assemblies directly overlaps civilian avionics component troubleshooting and repair.

How to prepare: Compare your assembly repair experience with avionics bench-repair openings and use the ASTM NCATT AET exam topics to identify preparation gaps. Work maintaining, adjusting, or internally repairing FCC-licensed aviation radiotelephone transmitters calls for the General Radiotelephone Operator License.

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.

Telecommunications Equipment Installers and Repairers, Except Line Installers

Testing and repairing airborne communications assemblies transfers to isolating faults and verifying repairs in civilian telecommunications equipment.

How to prepare: Complete a hands-on telecommunications equipment lab covering circuit fault isolation and post-repair testing to bridge from airborne assemblies to ground communications equipment.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
