Test Range Utilization at 12% weather, recharge and reset allowance: a worked example

This scenario runs the test range utilization calculation on the strong side: 12% weather, recharge and reset allowance, with every other input held at its documented default. Use it when test range utilization in uav and drone manufacturing needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Test flights to complete on the range: 120 units (unchanged)
  • Flight test throughput per minute: 12 units / min (unchanged)
  • Weather, recharge and reset allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where weather, recharge and reset allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when scheduling range slots, sizing pilot and observer crews, or committing to a delivery date that depends on completing flight validation. 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

  • Required test range utilization time: 11.2 hr (headline result)
  • Base test range utilization time: 10 hr
  • Test range utilization allowance applied: 12 %
  • Test range utilization completion rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Test Range Utilization calculator, which recalculates instantly and can be shared with the inputs intact.
