Aerospace Lot Traveler Load at 37% routing rework time allowance: a worked example

This scenario runs the aerospace lot traveler load calculation on the strong side: 37% routing rework time allowance, with every other input held at its documented default. a production planner needs to estimate traveler processing effort for an aerospace build lot

The inputs for this scenario

  • Traveler operation signoffs per lot: 185 signoffs (unchanged)
  • Inspector signoff pace: 4.2 signoffs/min (unchanged)
  • Routing rework time allowance: 37 % (raised for this scenario; the documented default is 32)

Working through the calculation

  • Applying the documented formula (Base traveler processing time = traveler signoffs รท processing pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 60.35 traveler hr for aerospace lot traveler load, the number this scenario is built around.
  • At this operating point the engine returns 44.05 traveler hr for base traveler processing time.
  • At this operating point the engine returns 37 % for routing correction allowance.
  • At this operating point the engine returns 4.2 signoffs/min for traveler processing pace.

How this compares with the baseline

  • Against the tool's baseline example, where routing rework time allowance sits at 32% and the headline result is 58.14 traveler hr, this scenario comes in 3.79% above the baseline at 60.35 traveler hr.
  • Use it when quoting a new aerospace lot, loading a work center, or estimating documentation labor for a build with a long, inspection-heavy router. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Aerospace lot traveler load: 60.35 traveler hr (headline result)
  • Base traveler processing time: 44.05 traveler hr
  • Routing correction allowance: 37 %
  • Traveler processing pace: 4.2 signoffs/min
