Squawk 7600 transmission — N603WM

2026-05-14 21:41 UTC· KHPN → KLEB· WHITE MOUNTAINS CAPITAL LLC· E55P

N603WM (White Mountains Capital) was operating from KHPN to KLEB on 2026-05-14. SkyMeter recorded a 7600 transponder transmission at 21:41 UTC. Code 7600 indicates a lost-comms / NORDO state; brief transmissions are often transient radio or transponder issues that resolve without crew action. Trace data at the event: 20874 ft AGL, 427 kt GS. Approach stability score: 25/100. 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 1 kt wind. 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.
