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.

Aircraft Cargo Handling Supervisors

Preparing equipment for air delivery, inspecting sling and airdrop loads, and supervising airborne missions transfer directly to aircraft cargo staging and securing operations.

How to prepare: Complete civilian aircraft cargo loading instruction that includes weight-and-balance calculations and load distribution exercises.

What the civilian work involves
  • Determine the quantity and orientation of cargo, and compute an aircraft's center of gravity.
  • Direct ground crews in the loading, unloading, securing, or staging of aircraft cargo or baggage.
  • Distribute cargo to maximize use of space.
Civilian tools and software (examples)
  • Cargo tracking system software
  • Microsoft Excel

Transportation Inspectors

Sling load and airdrop load inspection experience aligns with checking freight securement and observing loading for compliance with procedures.

How to prepare: Practice inspecting and documenting civilian freight securement against the loading procedures used by a target cargo operator.

What the civilian work involves
  • Inspect shipments to ensure that freight is securely braced and blocked.
  • Record details about freight conditions, handling of freight, and any problems encountered.
  • Observe loading of freight to ensure that crews comply with procedures.
Civilian tools and software (examples)
  • Microsoft Word
  • Adobe Acrobat
