I can understand where Chris is coming from.
I fly behind a Continental C90 (apparently an ice making machine).
So being well aware of that fact, flying recently towards low cloud, rain, foggy bits etc. I had the carb heat on, well in advance, rain streaming up the screen, down to 500ft, steering by the GPS, definitely "get home itis" situation.
The engine didn't falter. "No big deal", was not how I felt at the time, although that's how it turned out!
Carb ice can, with preparation, action, a working carb heat system etc, be resolved.
Airframe ice can make the thing unflyable long enough to kill you very quickly.
