The first stretched variant of the is likely to appear around MSN60 of the A350-900. Nevertheless, Program Executive Vice President Didier Evrard acknowledged that there is “a lot to do; nothing is taken for granted, nothing a given.”
Establishment of systems-installation design maturity is said to be “on plan,” while work continues on the variant’s structural design phase, which will permit the start of engineering drawing. Structural design maturity “incorporating all requirements” also was completed by mid-June.
The A350-1000 is already benefiting from the manufacturer’s experience with the A350-900. Evrard specifically cited 2 examples claimed to represent latest innovations: carbon-fiber-reinforced polymer door surrounds and engine-pylon composite spars.
Because Airbus needs to shorten the new variant’s overall testing time (relative to that for the initial model), it is making more extensive use of simulation, said Evrard.
