Airport Ramp GSE Duty Cycle Capacity at 63% gse equipment availability: a worked example

This worked example runs the airport ramp gse duty cycle capacity numbers for a tougher week than the baseline: 63% gse equipment availability instead of the typical 88%. Estimate usable ramp duty cycle capacity from aircraft turns per cycle, available operating cycles, equipment availability, and completed-turn yield.

The inputs for this scenario

  • Aircraft turns supported per cycle: 5 turns/cycle (held at the documented default)
  • Available ramp operating cycles: 72 cycles (held at the documented default)
  • GSE equipment availability: 63 % (the input this scenario stresses; the baseline uses 88)
  • Completed-turn service yield: 96 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross ramp turn capacity = aircraft turns supported per cycle × available ramp operating cycles.
  • Usable ramp turn capacity works out to 218 aircraft turns at these inputs, and this is the headline figure for the scenario.
  • Gross ramp turn capacity works out to 360 aircraft turns at these inputs.
  • Turns lost to GSE unavailability works out to 133 aircraft turns at these inputs.
  • Turns lost to incomplete service cycles works out to 9.07 aircraft turns at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where gse equipment availability sits at 88% and the headline result is 304 aircraft turns, this scenario comes in 28.41% below the baseline at 218 aircraft turns.
  • Use it when sizing a ramp GSE fleet against a flight schedule or evaluating whether current equipment can absorb a peak bank. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Usable ramp turn capacity: 218 aircraft turns (headline result)
