Squawk 7600 transmission — DAL1354
2025-12-25 11:52 UTC· KIAD → KATL· DELTA AIR LINES INC· BCS3
DAL1354 (Delta AIR Lines) was operating from KIAD to KATL on 2025-12-25. SkyMeter recorded a 7600 transponder transmission at 11:52 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: 30673 ft AGL, 440 kt GS. Approach stability score: 66/100. Scores in this band occur on roughly 10-15% of approaches at this runway, with multiple gates outside the per-runway envelope. METAR at the time reported 1 kt wind, 1 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.
