1. Crosswind & Wind Shear Limits
Major coastal airports like JFK (Runways 04/22, 13/31), EWR (04/22), and BOS (04/22, 09/27) have fixed runway orientations. When northeasterly coastal gales exceed 35-45 knot crosswind components with low-level wind shear, safe transport-category airliner landing limits are violated, dropping Arrival Acceptance Rates (AAR) to near-zero.
2. The Tail & Crew Turnaround Cascade
Aircraft operate in linked chains (e.g., ORD → LGA → MIA → DFW). A 3-hour ground stop at LGA delays the aircraft's onward leg to Miami. Flight crews hit mandatory FAA Part 117 flight duty period limits, triggering cancellations hundreds of miles away in calm weather due to displaced tails and illegal crews.
3. Ground Delay Programs (GDP) vs Reroutes
Rather than letting flights circle in holding patterns and burn contingency fuel until declaring minimum fuel emergencies, the FAA Air Traffic Control System Command Center (ATCSCC) issues EDCTs (Expect Departure Clearance Times) holding aircraft on origin tarmac, or orders bypass routing through inland waypoints.
