HKE629 was operating from RJTT to ZGNT on 2026-06-15. SkyMeter detected a long landing rollout at Shenzhen Nantou Heliport (ZGNT) on runway 11H at 21:47 UTC. Trace data at the event: 0 ft AGL, 16 kt GS, 0 fpm vertical. Approach stability score: 73/100. Scores in this band are observed on roughly 25% of approaches at this runway: one or more gates outside the per-runway tightest envelope, but still inside the typical operating range. METAR at the time reported 4 kt wind, 3 kt crosswind component. A long landing rollout is detected when ground deceleration after touchdown is below the per-runway P10 envelope. It is an observational measure of rollout efficiency, not a runway-exit incident. Detection algorithm and known limitations: see SkyMeter methodology.

Automated analysis. Events shown on this page (such as go-around, unstable approach, or runway events) are heuristic classifications produced by algorithms from publicly broadcast ADS-B data. They are intended to surface flights of interest for further review — they are not findings of fact, and they do not determine pilot fault, regulatory compliance, or the cause of any occurrence. Coverage gaps and sensor noise can affect accuracy. Only the relevant civil aviation authority or accident investigation body can make official determinations.
