Ok, I know this is one of those "it depends" answers, but I'm curious as to
what folks are willing to do in the winter time.

Assumptions:

Single engine piston aircraft with NO de-icing equipment.

Situation:

It's wintertime. You want to fly XC and there are midlevel clouds in the
forecast with the potential for icing to occur.

It looks like the band is thin enough to climb through and cruise in the
clear above the weather.

SO:

1) If the cloud layer is forecast to potentially have icing, can you legally
and would you climb through the layer to get up high for your trip? how
thick a layer, type of forecast, time spent in the layer, etc. What would
you be willing to risk transition through possible icing?

I believe the recent interpretations is that this would be illegal as
the cloud layer at below freezing temps would constitute an area of
"known" icing and thus penetrating it would not be legal. As to what I
would do personally ... well, I won't answer that here! :-)


2) Would that change any if those same conditions were now reported icing
from a recent PIREP?

It would change my personal view of the situation, but I don't think it
changes the legality.


3) If it's reported, can you transit the cloud layer legally?

I don't believe you can do so legally.


4) Let's say yoru trip starts off VFR but by the time you get to your
destination, a cloud layer has formed that has reported icing in it. Can or
or would you be willing to transit this layer to land at this destionation
or would you turn around or divert to land someplace to stay out of the
clouds?

Again it depends, but if I had sufficient fuel, I'd probably divert. If
I was low on fuel, I'd descend through the layer.
