Stall warning — STY543

STY543 (Altius Aviation) was operating from KFRG to KBOS on 2026-05-31. SkyMeter detected a stall warning at 13:23 UTC. Trace data at the event: 9381 ft AGL, 250 kt GS. METAR at the time reported 5 kt wind, 4 kt crosswind component. A stall flag is raised when the inferred angle of attack and observed airspeed are consistent with a stalled wing. Stall events on general-aviation trainer aircraft are predominantly stall-recognition practice during primary flight training, not safety-of-flight incidents. 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.
