Squawk 7700 transmission — DAL2547
2026-08-30 18:14 UTC· KGRR → KATL· DELTA AIR LINES INC· B739
DAL2547 (Delta AIR Lines) was operating from KGRR to KATL on 2026-08-30. SkyMeter recorded a 7700 transponder transmission at 18:14 UTC. Code 7700 indicates a general emergency declaration (e.g. engine, medical, smoke). A sustained transmission is normally accompanied by ATC priority handling. Trace data at the event: 35148 ft AGL, 463 kt GS. Approach stability score: 92/100. Scores in this band are observed on roughly 50% of approaches at this runway and represent the centerline of normal operations. METAR at the time reported 5 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.
