What this dataset tests
Whether a system can convert detected phase-space distortion into a maintenance horizon and schedule.
The point is not fault blame. It is safe remaining cycles and workload risk.
Required outputs
- integrity_horizon_flights
- maintenance_priority
- workload_risk_index
- oscillation_risk_probability
- replacement_window
- intervention_rationale
Scoring conventions
- horizon is remaining flights to unacceptable integrity risk
- workload and oscillation risk range 0 to 1
- replacement window is an actionable flight bound
- priority is low, medium, high, or urgent
Use case
Layer three of Flight Control System Phase-Space Integrity Map.
Supports:
- fleet-level trend maintenance planning
- early actuator replacement before oscillation
- reduced pilot workload through proactive scheduling
