Apart from a quick trip to Hamburg in December when temperatures got down to -10°C, the Grizzly team has spent most of its time in the relatively benign climate of Seville and Toulouse. But over the last couple of weeks that has all changed.

First Grizzly 2 and then Grizzly 3 have been to Kiruna in northern Sweden at a latitude of 67° 49'N to set about cold weather testing in earnest. On the first visit, during which temperatures dropped to about -21°C, the focus was on the powerplants following overnight 'cold-soaks', including the propeller controls which have to move those mighty eight-blades on each engine. On the second trip there was more emphasis on the aircraft's other systems, as explained in this very nice video filmed by our own Sylvain Ramadier.
