Speed exceedance — BOX397

▶ Replay 📊 Analyse

BOX397 was operating from KCVG to EDDP on 2026-05-19. SkyMeter detected a speed exceedance at 03:56 UTC. Trace data at the event: 25009 ft AGL, 502 kt GS. METAR at the time reported 4 kt wind, 4 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.

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.
