Why are some aircraft able to fly in extremely cold climates (such as the Poles)? What causes them to not freeze over?

I am a huge fan of flight simulation games (and aircraft mechanics in general), and this is a question that has always been interesting to me. Why are some crafts able to fly in super cold areas without freezing over and inevitably plummeting, while others have basically no chance of staying airborne?

The big high-altitude commercial aircraft are designed to operate at -55 degC. It’s a basic industry standard. At 50k ft altitude, flying over the poles doesn’t really mean anything because it is just as cold at the poles as it is somewhere else (roughly).
