UAV & Drone Manufacturing worked example

Final Inspection Burden at 12% setup, handling, and rework-retest allowance: a worked example

What does the result look like when setup, handling, and rework-retest allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when final inspection burden in uav and drone manufacturing is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Aircraft to inspect this run: 120 units (unchanged)
  • Aircraft inspected per minute at final QC: 12 units / min (unchanged)
  • Setup, handling, and rework-retest allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base final inspection burden time = final inspection burden workload รท final inspection burden completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required final inspection burden time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base final inspection burden time.
  • At this operating point the engine returns 12 % for final inspection burden allowance applied.
  • At this operating point the engine returns 12 pieces / min for final inspection burden completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and rework-retest allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when setup, handling, and rework-retest allowance is genuinely sustained, not just peaked for a shift. It assumes a steady inspection rate; a spike in defects that forces rework and retest cycles will push actual time well beyond the flat allowance.

Results at a glance

  • Required final inspection burden time: 11.2 hr (headline result)
  • Base final inspection burden time: 10 hr
  • Final inspection burden allowance applied: 12 %
  • Final inspection burden completion rate: 12 pieces / min
