Upset — N406AX

2026-04-09 13:48 UTC· SC05 KNBC· AIRBORNE TACTICAL ADVANTAGE CO LLC· KFIR

N406AX (Airborne Tactical Advantage) was operating from SC05 to KNBC on 2026-04-09. SkyMeter detected a upset at 13:48 UTC. Trace data at the event: 18472 ft AGL, 517 kt GS. Approach stability score: 23/100. 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 25 kt wind, 16 kt crosswind component. 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.
