Steve76,
The #3 S-92 will go to Alaska next month for it cold wx certification which will take about 1 month. We have had a good spell in the climatic hangar at Eglin AFB (some unwritten rule of fligh test says that you go to the cold wx chamber in July in Florida!).
GLS is right, time gets kinda slow at -40C!
We also launch the snow tests in #4 in January, which are always interesting. We have to show no problems in snow warmer than -3C, with visibilities below 1/4 mile, which usually means indefinate ceiling below 100 feet. Interesting flying weather. In the 76, we were the only thing flying within 100 miles when we did those tests!
