Go-around — TLM539

VTBD · 21R

2026-01-19 08:58 UTC· B739

TLM539 was inbound to VTBD on 2026-01-19. SkyMeter detected a go-around at Don Mueang International Airport (VTBD) on runway 21R at 08:58 UTC. Trace data at the event: 422 ft AGL, 153 kt GS, 0 fpm vertical. Approach stability score: 85/100. Scores in this band are observed on roughly 25% of approaches at this runway: one or more gates outside the per-runway tightest envelope, but still inside the typical operating range. METAR at the time reported 3 kt wind, 9,999 m visibility. A go-around is a discontinued landing approach in which the pilot adds power and climbs back to a safe altitude before re-attempting the approach or proceeding to an alternate. It is a routine safety response, not an emergency, and is taught as the standard reaction to any unstable approach. 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.
