Last week, the extra-body jet tested its ability to operate on wet runways at Istres, France, travelling successfully through water troughs.
“This test validates how the aircraft would behave on a very rain-soaked runway, and verifies that neither the water under the aircraft nor the spray generated by the nose landing gear will enter the engines or APU (auxiliary power unit),” the European manufacturer said.
The four A350 test aircraft have now accumulated about 1,600 hours in over 350 flights, Airbus added.
The A350 features an extra wide cabin with a non-stop flying capability of more than 15,000 kilometres.
It will be built in three versions – A350-800, A350-900 and A350-1000. Qatar Airways, with an order for 80 A350s, is the top customer.
In all, Airbus has received 812 orders from 39 customers worldwide.
