Hot-weather testing of the Airbus A350-1000 is underway in the United Arab Emirates after one of the three flight-test airframes arrived in Al Ain.
The aircraft, MSN65, arrived at Al Ain on 4 July, landing on runway 01 following its flight from Toulouse.
Airbus has not indicated how long it will spend at the airport but typically hot-weather testing spans several days.
As well as flight-performance tests, the aircraft is likely to undergo behavioural checks of its Rolls-Royce Trent XWB-97 engines and cooling systems, and be subjected to a heat-soak.
Al Ain is currently experiencing temperatures of around 46C, according to the airport's meteorological data.
Airbus is aiming to deliver the first A350-1000 to Qatar Airways by the end of this year.
