Method. Landing events are detected from raw ADS-B tracks, the runway is
scored from ground-level threshold evidence and final-approach geometry, and each
arrival is classified by how it entered the circuit. Circuit Compliance compares the flown
circuit side against the published direction (Left-Hand or Right-Hand) for the runway. Data is limited by ADS-B Coverage. Data provided by ADSB Exchange.
Not for navigation. Runway geometry is approximate — verify against current CFS/CAP.
