Following the Bolivia and Canada trials, the A350 will undergo another round of extreme temperature tests in May, but this time it will use the McKinley Climatic Laboratory at Eglin Air Force Base in Florida.
The hangar will be cooled down to temperatures of around -40 degrees Celsius and heated to reach +45 degrees Celsius. The hangar has been used by many previous programs including, most recently, the Boeing 787.
Two months before, in March, natural icing tests will be completed.
