The site's monitoring system observed an aircraft arriving at Taiwan Taoyuan International Airport (TPE). According to public ADS-B observation data, the aircraft bore registration B-2017, with ICAO hex 7809f0, aircraft type display name B734, and callsign CSS266. The operator ICAO is CSS, while operator IATA, operator name, operator Chinese name, and operator country or region are all listed as unidentified.
The observation record shows a first valid observation time of 2026-08-11T23:56:26Z and a confirmed arrival time of 2026-08-12T01:10:29Z. The arrival determination is confirmed_arrival, with the confirmation basis being that the aircraft was located within the airport geofence and alt_baro indicated ground level. The number of valid observation records is 2.
The primary data source for this observation is Airplanes.live, with a secondary data source of ADSB.lol. The cross-confirmation status is secondary_unavailable, indicating that the secondary data source could not provide cross-referencing data during this observation period. The airport ICAO code is RCTP, and the airport name is Taiwan Taoyuan International Airport.
The statistics note states that the system's observation history is still accumulating, with no comparable long-term statistics available. Consequently, this observation combination lacks a long-term comparison baseline within the site's system, and no frequency or rarity inference should be drawn against historical records. The event ID is fw-7b04d5d22c1eab80.
Because operator IATA, operator name, operator Chinese name, and operator country or region are all marked as unidentified, the site cannot confirm from the observation data which airline operates this aircraft or its national affiliation. The CSS code in callsign CSS266 corresponds to the operator ICAO field, but the observation data itself provides no further operator identification. This report records the arrival event based solely on observation data and does not speculate on the aircraft's purpose, route, charter arrangements, or operator identity.
