WJA455 (Westjet) was operating from CYYZ to CYEG on 2026-08-19. SkyMeter detected a stall warning at 18:32 UTC. Trace data at the event: 1123 ft AGL, 104 kt GS. Approach stability score: 85/100. 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, 3 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.

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.

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.
