FFL938 (Efficiency Aloft) had departed KSTS on 2026-05-30. SkyMeter detected a return to field at Charles M. Schulz Sonoma County Airport (KSTS) on runway 20 at 22:24 UTC. Peak altitude 9,804 ft, turnaround area near Monte Rio, US. Approach stability score: 28/100. 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 0 kt wind, 16,093 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.
