Aerospace Capacity Reserve at 62% reserved equipment uptime: a worked example
Suppose reserved equipment uptime falls to 62%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate reserved good-part capacity from output per production cycle, reserved cycles, equipment uptime, and aerospace route yield.
The inputs for this scenario
- Output per reserved production cycle: 42 parts/cycle (held at the documented default)
- Reserved production cycles: 36 cycles (held at the documented default)
- Reserved equipment uptime: 62 % (the input this scenario stresses; the baseline uses 86)
- Aerospace route yield: 93 % (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Gross reserved capacity = output per cycle × reserved cycles.
- Usable aerospace capacity reserve works out to 872 reserved good parts at these inputs, and this is the headline figure for the scenario.
- Gross reserved capacity works out to 1,512 reserved good parts at these inputs.
- Reserve downtime loss works out to 575 reserved good parts at these inputs.
- Reserve yield loss works out to 65.62 reserved good parts at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where reserved equipment uptime sits at 86% and the headline result is 1,209 reserved good parts, this scenario comes in 27.91% below the baseline at 872 reserved good parts.
- It computes the usable good-part reserve from gross reserved capacity after applying equipment uptime and aerospace route yield, and breaks out the downtime and yield losses. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
