About the only thing you can glean for certain from these threads is that the procedures related to the topic are poorly defined and, often, poorly understood. Different States have different policies, perhaps even with local differences in application. Different operators have different procedures in their OMs, perhaps even a few with no reference to the topic (and I'm thinking of the ones that might operate in low temperatures). And different navigation technologies and systems function differently when handling cold temperature corrections.
Oh, and none of it is very transparent.
It is clearly a potential and specific hazard in your environment - I wish you well in getting a safe solution in place. In theory, any (and your) Safety Management System should have a method of handling the concerns that you raise.
