Thanks again, Lou.

Those details show the real workload and thinking behind flying in my eyes. We sim pilots maybe check one or two lamps being lit or not and then don't care.
Having the duct routing in mind and also the consequences when this or that one gets punctured is far beyond the sim horizon, but one can play around a bit with the current planes there.
So once again, a thumbsup for your explanations and also to CS for having quite some switches and gauges modelled there.

Where did you have your worst ice experiences? Coming in on a winter's day at the American Eastcoast, doing some Canadian locations or approaching Greenland?

I always turn on the anti-ice stuff when descending into warmer and more humid air (which should be the case most of the time) with my rather cold aircraft.
Although the skin friction heats me up a bit (on the subsonic things while the supersonics get speed limited by just that huge heat), my thinking is that the warmer and more humid air at lower altitudes will condensate at my aircraft's surfaces.
Also, when coming in with anti-ice on at the approach, my speeds (and therefore power settings) are a bit higher to give enough airflow in the a/i system.
I'm also leaving my flaps down after landing.
Is that the correct thinking/acting?
