Squawk 7700 transmission — CTP881

CTP881 (Citation Technology Partners) was operating from KSDL to KPHX on 2025-08-22. SkyMeter recorded a 7700 transponder transmission at 00:44 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: 7474 ft AGL, 242 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 3 kt wind, 2 kt crosswind component. Detection algorithm and known limitations: see SkyMeter methodology.

All events on this flight

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.
