Does the documentation entry come from AS9100?

No, enter the time required by your inspection and record-control procedures. A fixed percentage is not supplied by this calculator.

Should repeated checks be counted?

Yes, include each planned verification in the characteristic count. Do not count the same repeat again in setup or review time.

Can I divide labor hours by the number of inspectors?

Only when the work can be split without interference. The result measures labor effort; it does not establish elapsed completion time.

What if different features take very different times?

Run separate groups with comparable inspection methods and add their labor. A single pace can hide a slow subgroup.

Aerospace & Defense Manufacturing calculator

Aerospace Inspection Burden Calculator

Estimate labor for a defined aerospace inspection plan. Enter the characteristic count, measured verification pace, setup minutes and documentation review minutes.

What this calculator does

Plan inspection labor from measured verification pace and separate setup and documentation time.

Formula used

Measurement hours = characteristics ÷ verification pace ÷ 60
Setup and review hours = (setup minutes + review minutes) ÷ 60
Total inspection hours = measurement hours + setup and review hours
Total inspection minutes = total inspection hours × 60

Inputs explained

Characteristics to Verify: Count from the inspection plan, including every planned repeated verification.
Verification Pace: Measured pace for these characteristics using the planned inspection method.
Inspection Setup Time: Recorded setup labor for this inspection job, excluding measurement time.
Documentation Review Time: Planned labor to complete and review this inspection record.

How to use the result

Best suited to inspection labor Estimate, metrology staffing plan.
Machine dwell and queue time require a separate elapsed-time schedule. Documentation time comes from your procedure, not a universal aerospace percentage.

Current U.S. benchmarks

Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
The U.S. has 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).
