Squawk 7600 transmission — ISR581

2026-07-20 16:17 UTC· LLBG LCLK· A320

ISR581 was operating from LLBG to LCLK on 2026-07-20. SkyMeter recorded a 7600 transponder transmission at 16:17 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: 27805 ft AGL, 394 kt GS. Approach stability score: 72/100. Scores in this band are observed on roughly 25% of approaches at this runway: one or more gates outside the per-runway tightest envelope, but still inside the typical operating range. METAR at the time reported 11 kt wind, 11 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.
