The Airbus A350-900 is the initial and shorter passenger variant of the Airbus A350 family. It is a twin-engine, long-range widebody airliner certificated as the A350-941 and powered by Rolls-Royce Trent XWB-84 engines. The variant first flew in June 2013, entered service with Qatar Airways in January 2015 and forms the numerical core of the A350 fleet.[1]Airbus A350 Family facts and figures — January 2022Airbus · airbus.com · Accessed 2026-08-29Open source details[2]EASA Type Certificate Data Sheet EASA.A.151European Union Aviation Safety Agency · easa.europa.eu · Accessed 2026-08-29Open source details
Development and certification
The A350-900 was the first A350 variant to enter flight testing and production. MSN001 made the type's maiden flight from Toulouse on 14 June 2013. Five development aircraft accumulated more than 2,600 flight hours during a test programme lasting a little over fourteen months.[1]Airbus A350 Family facts and figures — January 2022Airbus · airbus.com · Accessed 2026-08-29Open source details[3]Test and certificationAirbus · airbus.com · Accessed 2026-08-29Open source details
EASA issued the A350-941 type certificate on 30 September 2014, followed by FAA validation on 12 November. Airbus delivered the first aircraft to Qatar Airways on 22 December 2014, and the airline began commercial service on 15 January 2015.[1]Airbus A350 Family facts and figures — January 2022Airbus · airbus.com · Accessed 2026-08-29Open source details[2]EASA Type Certificate Data Sheet EASA.A.151European Union Aviation Safety Agency · easa.europa.eu · Accessed 2026-08-29Open source details
The -900 established the baseline A350 structure, systems and cabin. The later A350-1000 shares a high proportion of its system part numbers and the same pilot type rating, but it is a separately certificated model with a longer fuselage, different landing gear, higher weights and higher-thrust engines.[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details[2]EASA Type Certificate Data Sheet EASA.A.151European Union Aviation Safety Agency · easa.europa.eu · Accessed 2026-08-29Open source details
Design
The A350-900 has a carbon-fibre-reinforced plastic fuselage and wing, a conventional tail, retractable tricycle landing gear and two underwing turbofan engines. Airbus states that more than 70 per cent of the airframe by weight uses advanced materials, including 53 per cent composites, together with titanium and modern aluminium alloys.[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details
Wing and flight controls
The 64.75-metre-span wing uses high-aspect-ratio geometry and variable camber: flight-control surfaces adjust the wing's aerodynamic shape during flight. Digital fly-by-wire controls and side-stick controllers follow established Airbus practice, while the A350 flight deck introduced large integrated displays and systems developed specifically for the type.[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details[5]Aircraft characteristicsAirbus · aircraft.airbus.com · Accessed 2026-08-29Open source details
The A350-900 is an ICAO Code E aircraft by wingspan. Airports and operators use its variant-specific planning data for stand geometry, pavement loading, servicing zones, jet blast and rescue access.[5]Aircraft characteristicsAirbus · aircraft.airbus.com · Accessed 2026-08-29Open source details
Engines and ETOPS
The certificated powerplant is the Rolls-Royce Trent XWB-84 family. The “84” identifies the nominal thrust class; the precise engine mark and approved thrust rating are part of an individual aircraft's configuration. The higher-thrust Trent XWB-97 belongs to the A350-1000 and is not an interchangeable marketing option for the A350-900.[2]EASA Type Certificate Data Sheet EASA.A.151European Union Aviation Safety Agency · easa.europa.eu · Accessed 2026-08-29Open source details[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details
EASA and the FAA approved extended-range twin-engine operations beyond 180 minutes. ETOPS approval supports routes remote from diversion airports, but an operator must also hold its own authorisation and meet continuing maintenance, dispatch and operational requirements.[6]FAA approves A350 XWB for beyond-180-minute ETOPSAirbus · airbus.com · Accessed 2026-08-29Open source details
Cabin and cargo
The fuselage is 5.96 metres wide externally. Airbus's February 2026 data gives representative three-class capacities of 332 passengers at nine-abreast economy seating or 352 at ten abreast, with a maximum certified capacity of 440. These are planning and certification values; actual airline layouts depend on exits, monuments, crew-rest installations and class mix.[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details
The lower deck accepts standard LD3 containers and pallets. Airbus publishes a maximum usable cargo volume of about 172 cubic metres, but passenger baggage, crew-rest modules and airline equipment reduce the volume available for revenue freight.[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details[5]Aircraft characteristicsAirbus · aircraft.airbus.com · Accessed 2026-08-29Open source details
Weight and range standards
“A350-900” covers multiple certificated weight standards rather than one payload-range combination. Airbus's February 2026 data distinguishes regional, basic and high-gross-weight versions with maximum take-off weights of 250, 268 and 283 tonnes respectively. Corresponding manufacturer range figures are 6,000, 7,500 and 8,500 nautical miles under Airbus assumptions.[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details
Operators can select or later upgrade certain weight capabilities where the aircraft's build standard and certification permit. A fleet record should therefore store the certified weight variant and modifications instead of assigning every A350-900 the highest published range.
A350-900ULR
The A350-900 Ultra Long Range is a mission-specific development of the A350-900, not a separate model number on the EASA type certificate. It uses a higher fuel-capacity and weight standard, together with associated systems and cabin provisions, for flights of up to 9,700 nautical miles in Airbus's published configuration.[7]Airbus A350 Family facts and figures — April 2025Airbus · airbus.com · Accessed 2026-08-29Open source details[2]EASA Type Certificate Data Sheet EASA.A.151European Union Aviation Safety Agency · easa.europa.eu · Accessed 2026-08-29Open source details
Singapore Airlines introduced the A350-900ULR on 11 October 2018. Its low-density layout was designed around ultra-long sectors, illustrating why the ULR's operational capacity should not be confused with the A350-900's maximum certificated seating.[1]Airbus A350 Family facts and figures — January 2022Airbus · airbus.com · Accessed 2026-08-29Open source details

Dimensions and performance are current manufacturer planning values. Airline-specific operating weights, payload, reserves, winds, temperature and runway conditions determine actual capability.[4]Airbus A350 Family facts and figures — February 2026Airbus · mediaassets.airbus.com · Accessed 2026-08-29Open source details[5]Aircraft characteristicsAirbus · aircraft.airbus.com · Accessed 2026-08-29Open source details
Production and operators
Final assembly takes place at Toulouse. Airbus's July 2026 report records 1,601 A350-family orders and 731 deliveries, but the public summary combines the A350-900 and A350-1000. Exact -900 orders, deliveries and customer allocations must therefore be taken from the dated model-level workbook rather than inferred from the family total.[8]Airbus orders and deliveries — July 2026Airbus · airbus.com · Accessed 2026-08-29Open source details
Qatar Airways was the launch operator. The A350-900 has subsequently entered service with network and long-haul operators in every major region, including Singapore Airlines, Finnair, Cathay Pacific, Lufthansa, Delta Air Lines, Air France and Japan Airlines. This is illustrative rather than a current fleet census; leases, transfers and storage status change over time.[9]Airbus delivers its 100th A350 XWBAirbus · airbus.com · Accessed 2026-08-29Open source details[8]Airbus orders and deliveries — July 2026Airbus · airbus.com · Accessed 2026-08-29Open source details
The variant supports conventional long-haul routes, high-capacity regional operations and ultra-long-range services through different weight and cabin standards. Registration-level records should link the airframe's MSN, engine marks, operator, configuration and dated status rather than treating an airline order as proof of current operation.
