Squawk 7600 transmission — HRT421

HRT421 (Chartright Air) was operating from KBUF to KPSK on 2026-07-14. SkyMeter recorded a 7600 transponder transmission at 13:24 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: 6187 ft AGL, 189 kt GS. Approach stability score: 86/100. 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, 4 kt crosswind component. Detection algorithm and known limitations: see SkyMeter methodology.

SkyMeter cross-referenced this flight against FAA-published TFRs that were active during its window and within its geographic bounding box. Overlap doesn't necessarily mean violation — the aircraft may have been outside the TFR’s precise polygon or flying under air-traffic-control coordination.

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.
