Speed exceedance — PSC1122

2026-04-18 01:00 UTC· CYMX CYHU· 9736140 Canada Inc. (Pascan Aviation)· DHC3

PSC1122 (9736140 Canada Inc. (Pascan Aviation)) was operating from CYMX to CYHU on 2026-04-18. SkyMeter detected a speed exceedance at 01:00 UTC. Trace data at the event: 2879 ft AGL, 168 kt GS. METAR at the time reported 5 kt wind, 5 kt crosswind component. An overspeed flag is raised when observed indicated airspeed exceeds the aircraft type's published Vmo (maximum operating speed) or Mmo (maximum operating Mach). Compressibility-correction bugs were a major false-positive source on the E75L and CRJ9 fleets prior to April 2026; current flags use the corrected IAS calculation. 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.
