McKinley’s Elgin Air Force lab is prepared to test the first A350 XWB to visit the US beyond certification requirements. An A350 XWB, serial number 2, is at the McKinley Climatic Lab in northwest Florida. Tests over the next few weeks will include extreme hot and cold temperatures across aircraft systems and cabin installations. Initial tests were performed earlier this year in the Middle East and northern Canada. There are four A350s in the XWB programme, which is on schedule to complete certification in late 2014.
