Let's put it in a way that you can understand. Any pilot with more than a couple of thousand hours (5000 is the minimum for the lhs from what I see) with average skills, proper discipline, the support of a competent training dept and and decent sops can handle winter ops in Norway or anywhere else for that matter.
I did, and I am nothing if not an average pilot at best.
Now, I can understand that it might hurt the ego of someone, but I am sure you will cope.
