Airbus A350 XWB Specifications.

Airbus are producing three variants of the A350, namely the Airbus A350 800, Airbus A350 900 and the Airbus A350 1000.  Building on technologies from the Airbus A380, the Airbus A350 XWB has the same fly by wire technology as well as a similar cockpit layout to the Super Jumbo. The use of new materials and manufacturing methodology produces in the region of a 10% reduction in maintenance costs as well as a 14% reduction in empty weight per seat compared to competitors.

To put things in perspective the use of modern materials between the Airbus A350 XWB and its most similar competitor, the Boeing 787 read as follows:

Material AIRBUS A350-XWB BOEING 787
Aluminium, Aluminium-Lithium (Alu-Li)

The new design makes it possible to pressurise the cabin to the equivalent of pressure found at

..cabin pressure is maintained at the equivalent of 6,000 feet with 20 percent humidity….

6,000 feet (1,800 metres), with humidity at 20%. The new airflow system is able to adapt to passenger numbers and adjusts accordingly with a draught free flow.

The fuselage has a constant diameter from door 1 to door 4 thereby not only maximising space available inside the aircraft but standardising all doors so that not so many spare parts have to be carried. The fuselage, as the designator XWB (Extra Wide Body) would indicate, is remarkable in that it is wider than both the A330 and A340 models. The A350 XWB has an external cabin width of 5.97 metres (19.6 feet) against the A330/A340 at 5.64 metres (18.5 feet).

The redesigned wing is the largest for a wide body single deck aircraft.

The redesigned wing is the largest for a wide body single deck aircraft. The wing is common to all three variants measuring 443 square metres (4,770 square feet). The wing sweep is 31.9 degrees for a span of 64.8 metres (213 feet) which is the same as Boeing 777-200LR / 777-300ER, although the Boeing aircraft have slightly less area. Gone are the traditional Airbus wingtip fences, to be replaced with a sabre like point taking up the outer 4.4 meters (14 feet) of the wing. The high-lift trailing edge of the wing uses the same hinge system as the A380 with spoilers covering the gap created when flaps are extended. The new wing design allows a cruising speed of mach .85 with a maximum operating speed of mach .89.

The nose section uses a similar design criterion to the Airbus A380, offering improved aerodynamics. The nose wheel is forward swinging as does the Airbus A380. The shape of the forward section allows a crew rest area to be placed further forward above the cabin ceiling which reduces its encroachment on the passenger cabin space. A trade-off study was conducted to determine the best construction material for the forward section. Composite materials would have been an obvious choice due to weight benefits, however, extra strength is required to allow for bird strikes and if composites were employed then extra titanium would be required to bolster the strength. The decision was made to go with aluminium.

Instead of the traditional 4 flight deck windows, A350 XWB has 6 giving not only a wider field of vision but also with the spread of the load carried by the window posts the centre post can be thinner improving forward vision.

The A350 XWB cockpit carries 6 LCD screens of a 38cm (15in) diameter. Two are located in the centre of the panel one above the other above the thrust levers. Each pilot has their own primary, flight and navigation panels. The system is designed to allow for the addition of new technology as it comes in the future.

Pilots also benefit from a Head Up display (HUD)

Pilots also benefit from a Head Up display (HUD), where primary information is projected onto a clear screen in their forward line of sight much like fighter pilots so that they never have to take their eyes off the outside world.

The Integrated Modular Avionics (IMA) found on the A380 have been improved upon with the system handling 40 functions against the A380s 23. These include functions such as; Undercarriage, air systems, pneumatics and fuel. The benefits, of course, will be weight reduction as fewer processors are required on board, as well as a more stable system running a 100 Megabit per second network.

There are two Trent XWB engines to provide power to all A350 XWB variants. Details can be found in the table further down this page.

Advanced technology gained on the creation of the Trent 900 for the A380 and Trent 1000 for the Boeing 787 will obviously benefit the A350 XWB. In addition, the advances in noise dampening ensure that A350 XWB has state of the art solutions.

Airbus have adopted a three-prong main landing gear configuration with the two main prongs attached to the rear wing spar forward and to a gear beam to the rear which is itself attached to the wing and fuselage. The use of composite materials in the wing construction requires a more even distribution of weight. The main gear will come in four and six wheel bogies. Four for the -800 and -900 variants and six for the heavier longer range -1000 and also the -900r being proposed for British Airways to enable a London to Sydney non-stop type range.

As already mentioned, there are three variants of the Airbus A350 XWB. Some important points to note about these are:

  2. There seems to be wrong wing span for -1000. It should be same as for -800 and -900, 64.75m. Greetings!

    1. Hi Lech,

      thank you so much for spotting the mistake. I have now updated this to reflect a common wing span of 64.75M for all variants.

      Thanks for stopping by and taking the time to comment.

      Regards Peter

  3. Hi,

    I stopped by and to check the MTOW and MLW, due to since long time ago flight simulator yesterday and it was hard to land… Nose very high up.. Of course it was too heavy..should have done some jettisoning first.. Anyway it was happy a landing etc..

    Next fligth with 205t, not 260t

    BR from Finland


    Thanks by the good specs informations 😀

    1. Hi Julia,

      Thank you for stopping by. I love Flight Simulator. Although I must admit I haven’t had time to get the A350 yet. I will do that soon and give it a test.
      Happy flying.

      Cheers Peter

  7. I enjoyed flying with Lufthansa’s A350 from Canada to Germany. Very comfortable seats, modern infotainment equipment, quiet. It is funny how the toilets are placed “downstairs”, grouped, 4 of them if I remember.

  8. What is the thickness to chord ratio of the A350-900 wings? And where is the maximum thickness located? How about the thickness to chord ratio of the horizontal and vertical stabilisers?

    Thanks for reading,


    1. Hi Vasco,

      good question. We will look into it for you, unless someone else has that information they would like to share.

      Cheers Peter

    1. Hi,

      stall speed is dependent on many factors so is a bit of a moving target. It is continually computed by the PRIMs based on weight, altitude and configuration.

      You could calculate the stall speed from Vapp, which is VS1g (stall speed at 1g) x1.23*. Taking a fairly normal Vapp of 140, this gets you a stall speed of 114 with flaps full. But again, it is dependent on weight, altitude and configuration.

      * Vapp is also limited to a minimum of VMCL + 5.

        1. Hi, and thanks for stopping by. I’m not sure where you are seeing 114. Certainly would like to fix any mistake you have found. Thanks for the heads up.
          Cheers Peter

  10. Hi guys.

    The MTOW of the A350-1000 is now up to 316t (and is likely to be raised by Airbus again soon).

    Keep up the good work on a great website

  11. Hi.
    I work for Rolls-Royce as a fitter building the XWB A350 engine, currently I’m building both the 84K and 97K, but can never recall building a 74K. When was the 74K first put into service as the first engine we built was the 84K.
    Kind regards
    Gaz Block

    1. Hi Gaz,

      Thanks for stopping by. Does the following table taken from Wikipedia ring true to you?

      Designation Certified Net Take-off Rating Net Maximum Continuous
      Trent XWB-75 7 February 2013 74,200 lbf (330 kN) 66,600 lbf (296 kN)
      Trent XWB-79 7 February 2013 78,900 lbf (351 kN) 71,400 lbf (318 kN)
      Trent XWB-79B 7 February 2013 78,900 lbf (351 kN) 71,400 lbf (318 kN)
      Trent XWB-84 7 February 2013 84,200 lbf (375 kN) 71,400 lbf (318 kN)

  12. Hi Peter. I flew the A350-900 from Hong Kong to Perth, Australia. It was a bumpy flight. The cabin however was fantastic. I would fly it again no worries. I’m looking for to flying on the A350-1000 Perth to HK and the HK to Toronto in December.

    1. Hi Tony,
      that’s great, thanks for sharing. Yes there are more and more services to pick from these days as airlines are receiving their A350 orders. Did you feel any difference as far as jetlag and general wellbeing is concerned on arrival? The higher cabin pressure and humidity is supposed to reduce that hang over feeling.
      Yesterday I saw an Air China A350 parked next to an ANA Boeing 787 at Sydney Airport. It felt like a statement of this is the new normal, the age of the giant twins.

      Look forward to hearing about the A350 1000.
      Cheers Peter

  14. Hi Peter, is the wing really the largest for a wide body single deck aircraft? Would just like to confirm, can’t find anything else about it anywhere.
