Ground Operations & Hub Efficiency
Aircraft Turnaround Time (TAT) & Ground Cycle Simulator
Model the critical path of commercial flight turnarounds. Simulate parallel ground service equipment (GSE), passenger boarding dynamics, fuel hydrant throughput, and gate dwell buffers to benchmark fleet block hour productivity.
Ground Ops Fundamentals
- Simulates critical path ground activities: deplaning, fueling, catering, baggage handling, cleaning, and boarding.
- Evaluates dual-door vs single-door boarding efficiency and high-pressure fuel hydrant pumping throughput.
- Quantifies airline gate dwell penalties and aircraft daily block hour utilization gains.
Flight & Ramp Parameters
Turnaround Critical Path
Benchmark Target: 25 minutes
Calculated Turn 24.5 min
Critical Path Driver Passenger Boarding
Gate Dwell Variance -0.5 min ahead
Aircraft Daily Cycles 6.8 flights/day
Fuel Hydrant Rate 1,200 L/min
Efficiency Insight: Dual-door boarding reduces total passenger movement time by 38% compared to single-jetbridge operations, saving an average of 9 to 14 minutes per turn on high-density narrowbodies.
