JAL2742 was operating from RJCH to RJCO on 2026-05-22. SkyMeter detected a unstable approach at Sapporo Okadama Airport (RJCO) on runway 14 at 00:19 UTC. Trace data at the event: 925 ft AGL, 109 kt GS. METAR at the time reported 6 kt wind, 3 kt crosswind component, 9,999 m visibility. An unstable approach is one where the aircraft was outside the runway's normal envelope for at least one gate (glideslope, lateral deviation, descent rate, or IAS) at a defined altitude on final. The flag is advisory. It documents a deviation from the per-runway baseline, not an accident. 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.
