I wonder if an ATR 42 or 72 can answer if itīs possible
What i know it's NOT possible for an ATR 42/72 to speak...
possible for an ATR 72-2/500 (or 42-3/500 to take-off and land at a 850m runway in a cold weather.

Check out this document, you will find out all info you want to know about
ATR operations in freeeeeeezing cold weather....
I don't think ATR have any freeware performance documents for their aircraft
on the net.
And for a 30-45min flight?
What's the fuel burn of this type? Whats your ZFW? What's your alternate airport?
What is your flight time? Contaminated runway or not?
Many many factors...But as i newly said to you, ATR what i know doesn't have
any free for sharing performance diagrams.
