Should I be icing up?
Posted: Mon Mar 28, 2011 7:11 pmI've recently changed some of the settings I use in Active Sky Evolution and FSUIPC (now using DWC).
Visible moisture and temps below freezing.

Yes, that is what I thought...since posting my original, I conducted some test flights in Fair/Good conditions (without the 3rd party weather), and determined that there is most definitely something going wrong with my setup.

Posted: Tue Mar 29, 2011 6:36 amI'm not familiar with that model.. but at first glance (your image).. I see an airplane in icing conditions (estimating your altitude, subracting 2C per 1000 feet from the surface temps.. visible moisture)
But it sounds like that aiplane is modeled over-zealously for icing.
Is it done by "gauge", or is it coded into the mdl file ?

A career flight simmer like yourself doesn't have the J41?

Re: Should I be icing up?
Posted: Tue Feb 21, 2012 5:48 amWhat are the criteria for icing conditions?
In real-world ops, anti-ice is required at +6 C or below and visible moisture. Visible moisture means you can see clouds. You don't have to actually be in them. If the clouds are in your neighborhood and you can see them, that's visible moisture. The reason for the +6 is because local airflow around the airframe can cause adiabatic cooling well below what the free-air temp is.
From your screen shot and stated conditions, icing would be a possibility. I've had ice accumulation on the 737 (real-world) under the windshield wipers flying through nearly cloudless skies in the Pacific Northwest and Northern Europe. I'm not familiar with Active Sky Evolution or DWC, but it looks like they're doing a good job of replicating some realistic conditions.
