Airbus has carried out several days of cold-weather testing of the A321XLR, having flown one of the prototype twinjets to northern Canada.
The test aircraft – MSN11058, also known as FTV2 – departed Toulouse on 20 February for the airport at Iqaluit.
It undertook a number of flights, conducting circuits and approaches, while also undergoing ground checks in the harsh conditions.
Meteorological data from Iqaluit shows the temperature was around minus 33°C.
The aircraft, one of three XLRs in the certification fleet, is powered by Pratt & Whitney PW1100G engines.
Airbus says the aircraft returned to Toulouse on 24 February.
It is intending the A321XLR, which uses a specially-design large aft fuel tank to achieve long range, to enter service in the second quarter of next year.
