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.

Heating, Air Conditioning, and Refrigeration Mechanics and Installers

Inspecting, testing, maintaining, and repairing electrical and refrigeration systems on aircraft support equipment transfers directly to refrigeration service work.

How to prepare: Ask a local HVAC training or apprenticeship program to assess your support-equipment experience and identify gaps in building-system installation and service. Covered refrigerant work requires EPA Section 608 certification unless performed as an apprentice under close, continual certified supervision; some states and localities also require trade licensing.

What the civilian work involves
  • Test electrical circuits or components for continuity, using electrical test equipment.
  • Discuss heating or cooling system malfunctions with users to isolate problems or to verify that repairs corrected malfunctions.
  • Connect heating or air conditioning equipment to fuel, water, or refrigerant source to form complete circuit.

Mobile Heavy Equipment Mechanics, Except Engines

Operating, inspecting, testing, and repairing aircraft support equipment provides a practical foundation for diagnosing and servicing mobile heavy equipment.

How to prepare: Compare your documented equipment repairs with a target fleet's service tasks, then seek supervised training on unfamiliar machine systems.

What the civilian work involves
  • Repair and replace damaged or worn parts.
  • Test mechanical products and equipment after repair or assembly to ensure proper performance and compliance with manufacturers' specifications.
  • Operate and inspect machines or heavy equipment to diagnose defects.
Civilian tools and software (examples)
  • Fleet management software
  • Maintenance management software
