US Aviation Disruption Index →

A logistics-operations agent polls ADW-215 hourly; when disruption_score rises above 50 (from its current 20.0, which is at the 50th percentile of its two-observation history) and ground_stops covering three or more major hub airports appear in airports_affected, the agent automatically re-routes time-sensitive freight shipments to ground carriers, notifies affected customers with revised ETAs, and logs the FAA ASWS data reference in source_lineage for SLA-dispute documentation. The ground-stop weighting (weight 3x versus delay weight 2x) in methodology_version ensures the agent distinguishes systemic airspace halts — which cascade for hours — from routine weather delays that self-correct within 45 minutes. Real-time hourly refresh means re-routing decisions are made before connecting flights propagate the delay chain.

An airline operations director uses ADW-215 as an early-warning dashboard during IROP (irregular operations) events to pre-position ground crews and hotel accommodations before the full delay cascade hits connecting hubs. At a current score of 20.0 the system is near-normal; when the score jumps past 40 — particularly if the ground_stops field spikes — the director activates the IROP protocol and begins passenger rebooking workflows 30–60 minutes ahead of when FlightAware paid tools would surface the same information. Using the open FAA NAS feed rather than a proprietary airline data aggregator also avoids the $200K+ annual licensing cost of comparable commercial disruption platforms.
