HGB703 was operating from RCTP to VHHH (Hong Kong International Airport) on 2026-03-05. SkyMeter detected a diversion to Macau International Airport (VMMC) on runway 16 at 04:27 UTC. Peak cruise altitude FL400, turnaround area near Dongshan, CN. Approach stability score: 35/100. Scores below 50 occur on under 10% of approaches at this runway and indicate the v2 scorer flagged the approach as highly anomalous (three or more gates exceeded the runway's P90 envelope simultaneously). METAR at the time reported 10 kt wind, 6 kt crosswind component, 9,999 m visibility. 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.
