Tu204100S

Tu-204-100S is a designation that appears in some aviation references as a variant within the Tupolev Tu-204 family. The Tu-204 series is a Russian twin-engine, medium-range jet airliner developed by Tupolov and first flown in the late 1980s. The base Tu-204-100 served as the initial passenger version, with several derivatives introduced or proposed over the years, including later-generation models such as the Tu-204-200 and Tu-204-300.

Publicly available documentation does not consistently define a distinct Tu-204-100S model. Some sources treat the -100S as an export-oriented version, a specific certification package, or a field modification rather than a separately produced aircraft. Because of the inconsistent usage of the designation, there is no universally agreed set of technical characteristics that can be attributed to a standalone Tu-204-100S airliner.

In terms of design, aircraft within the Tu-204 family share a common configuration: a twin-engine, low-wing jet with a conventional tail and a two-crew cockpit, optimized for mid-range operations. Passenger capacity for Tu-204 variants generally falls within a broad range depending on layout, typically in the vicinity of roughly 150 to 210 seats.

Operational history for a distinct Tu-204-100S variant is not well documented in public records. Most widely documented Tu-204 operations have involved other -100, -200, or -300 derivatives. For precise specifications or confirmation of a Tu-204-100S, official Tupolov/United Aircraft Corp publications or dedicated aviation archival resources would be the authoritative sources.
