Icing in the scan...

Seeing several recent posts on icing situations, I was struck with a
curiosity of how much a part of watching for ice accumulation becomes a
part of your scan, for those of you who have flown into potential icing
conditions.

I've seen a lot of postings, regarding icing, and the places to look
for accumulation and I started to think about how I would feel being in
those conditions, and how it could be easy to fixate on looking for
ice!

I'm not asking, with the intention of flying into ice, but was curious
as to how the masses who have been in the ice, incorporate it into your
scan.

How much is too much? How fast is too fast? How often do you look?
Man... seeing the slightest trace of ice, I don't see how you could
pay attention to anything else!

Best Regards,
