FAR 91.157 Operating in icing conditions

I was able to climb above it and it was gone fairly quickly,


In freezing rain, there has to be warmer air above, with warmer water - the
source of the rain that then freezes when it falls through colder air below.
That helps remove ice. Though depending on conditions, that warmer water may
not be reachable.


Even if climbing wouldn't have removed it, can't you just turn around into
the warmer air?


Maybe. Probably. But if conditions are getting worse all over (night is
falling...) there may no longer be warmer air behind you.


Interestingly enough, while you say the FAA considers forecast icing =
known icing, it would seem that at least Richard L. Collins of Sporty's
disagrees.


Many people disagree. But they are not the ones that can pull your certificate.


Then he spends a fair amount of time
explaining the characteristics of icing, its relationship to Low pressure
and fronts, and escape tactics... This would strongly imply that at least
some pilots fly into forecast icing conditions, regardless of the
legalities...


Knowing about icing (beyond "Danger Will Robinson") is a good thing - a
necessary thing. Forecast or not, pilots will end up in ice and need to know
what to do (and what not to do) to extricate themselves before they have gone
too far the wrong way.
