KHHR · 252026-04-22 05:33 UTC· ALASKA AIRLINES INC· B39M
ASA561 (Alaska Airlines) was inbound to KHHR on 2026-04-22. SkyMeter detected a long landing rollout at Jack Northrop Field Hawthorne Municipal Airport (KHHR) on runway 25 at 05:33 UTC. Trace data at the event: 124 ft AGL, 0 kt GS, 0 fpm vertical. Approach stability score: 60/100. Scores in this band occur on roughly 10-15% of approaches at this runway, with multiple gates outside the per-runway envelope. METAR at the time reported 6 kt wind, 2 kt crosswind component, 16,093 m visibility. A long landing rollout is detected when ground deceleration after touchdown is below the per-runway P10 envelope. It is an observational measure of rollout efficiency, not a runway-exit incident. Detection algorithm and known limitations: see SkyMeter methodology.

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.
