Just to let you know... Even without the patch I can confirm the following:
I made several flights with her flying from Wichita in Kansas, USA to Friedrichshafen in Germany. Due to the range restrictions of the airplane I took the "northern route" crossing Canada and flying over Greenland to Iceland and UK (several hops / flights).
I was able to tackle severe storms with very low temperatures (sometimes manually because the AP, realistically, couldn't manage any more) and I also think I had several times icing effects. However, I was always able to manage without crash... and I didn't care that much about the weather in advance ;-). The only issue I had was the cabin temperature (but this is another thread and fix is coming up).
Here's what I did (please be aware I am no real pilot):
1.) Avoid moist air, namely clouds... Icing equipment shouldn't be an excuse to take needles risks. Of course many times I was not able to outclimb the clouds, etc. Then you have to rely on your Anti-ICE defenses.
2.) Use the Bypass handle if any Clouds or FOD
3.) Bleed Air always on while in climb and cruise (not for Take off and Landing !)
... and in order not to crash ...
4.) If I had any icing on the cockpit window I took the windshield and prop heat to on. But if there was any weather change (or I was coming out of the clouds)... I turned them off again... In doing so I "ensured" that I can see the icing conditions if they happen on my cockpit window and wings and reapply the procedure.
