ISSUE DESCRIPTION
After spawning to an airport parking spot with temperature below 0 degrees C (Live WX - Canada), the windshield freezes over resulting in total loss of visibility and no means to defrost.
FREQUENCY OF ISSUE
Every time on sim load.
REPRODUCTION STEPS
Please list clear steps you took in order to help our test team reproduce the same issue:
-
Live WX (in northern hemisphere) so you get below 0 C temperature and Assistance Icing Effect ON (refer to pic).
-
Load SR22 aircraft at airport parking spot. Start engine and set TEMP and FAN speed to max.
-
Windshield ice over without any means to defrost.
NOTE: I tried the same scenario in C172 / C208 Caravan and although some icing occurs on the side windows, the windshield is much clearer than the SR22. I tried the DA40 and windshield freezes over right away as well.

Personal Comments and Observations - this is not a Technical Support Response
Not sure this is an actual bug since you didn’t mention use of anti-ice fluid capability, which is present on the SR22T as part of it’s Flight Into Known Icing (FIKI) rating.
On the right side of the Bolster Panel directly under the PFD, there is an anti-ice fluid switch for the windshield. It must be manually activated and pressed several times until the windshield begins to clear. That’s what the 8 gals. of anti-ice are for in the load manager on the EFB for the SR22T.
That 8 gals. constitutes an upper limit of anti-ice capability - if you use too much of it on the ground, you may end up not having enough of it while airborne if you’re in a high precip / freezing cold airspace.
Ideally, the FBO would de-ice you as part of the run-up process and then you’d expedite your taxi and take-off to minimize further obscuration while still on the ground. Since none of the GSE ground support equipment) can simulate the de-icing, you could run the de-ice while on the ground then before take-off use the EFB to refill the fluid as a workaround.
If you’re icing that badly on the ground, that’s usually a sign that GA operations shouldn’t continue. But it’s the sim, no one’s really in peril. Nonetheless, if you’re playing the meta-game as well as the flight operations game, this would be a non-flying day…

When parked the ANTI-ICE SPEED does not work per SOP, see pic.
Also, the PUMP BKUP animation works ON/OFF but the switch is not functional/programmed, see second pic.
Thanks for the quick reply. I did try pressing the WIND SHLD switch several times and no joy!
Question is why other aircraft in the same wx condition will not have their windshield suddenly freeze over…?
Icing in this plane is very broken.
Was starting my flight, getting the preflight checks done, after around 5-10min the plane was completely covered in ice (windshield, wings, engine).
Zero visibility out of the windscreen
The plane was just staying on the ground, even engine was off and no wind.
Happened in moderate icing condition -2C and foggy.
Other GA planes I have flown seem fine and don’t have the issue.
Same issue for me, the wing shield is full of ice even with anti ice enable and pressed multiple times the wing shield button
ISSUE DESCRIPTION
The sim models windscreen icing when flying into icing conditions. But does not seem to model the windscreen defrost in the Cirrus SR22. There are cabin heat and fan controls, but there does not appear to be means to select windscreen defrost. Nor does any defrosting appear to happen.
This limits the usefulness of the FIKI capabilities of this airplane model - kind of hard to land when you cannot see out the windscreen.
FREQUENCY OF ISSUE
Whenever using this aircraft model flying into icing conditions.
REPRODUCTION STEPS
Please list clear steps you took in order to help our test team reproduce the same issue:
-
Use the Cirrus SR22 model from Microsoft from the marketplace.
-
Fly through icing conditions. Turn cabin heat to full hot and fan to full on.
-
Observe that the button on the cabin heating panel to select defrost are not clickable.
-
Observe the windscreen still ices over and obscures visibility.
Personal Comments and Observations
I wonder if this old 2020 trick will work.
Assign keybinds to:
TOGGLE ANTI ICE
TOGGLE STRUCTURAL DEICE
TOGGLE WINDSHIELD DEICE
These commands worked when I wanted to fly limited icing capability aircraft like the Asobo G36 on long-haul IFR. Even though some systems do not exist for all aircraft, the commands were still honored by the sim regardless of the plane used.
Yeah, it’s not realistic but I consider it a vanity control to balance out gameplay enjoyment.
I confirm those buttons are not clickable (seems functionality has not been implemented).
Not sure the fan & temperature controls have any effect on the cabin temperature and could defrost the windshield on the ground.
Is someone able to re-verify this bug on SU5? Is it possible to re-create using a custom weather setting? I was trying to re-create this by going to custom weather and dropping the temp, but I couldn’t get it to ice over.
In live weather, it’s hard to find somewhere cold now on this planet 
but I got a spot that was 0C and it wasn’t icing. Maybe not cold enough.
Still an issue in SU5.
CYRB now, live weather badbadweather.com :: Lowest temperatures
Not sure if the TEMP and FAN have any impact on the cabin temperature. And if they do, what the outside temperature range they have an effect to defrost the windshield ?.
Thanks for the tip. I’m there now. Clear skies. Live weather. It is starting to ice, slowly. Been here 5-10 minutes and I’m like this.
I’m trying to figure out if this bug is documented well enough and we think it’s confirmed to be a plane issue (rather than a larger sim issue). I’m in “bug escalation” mode right now 
but I don’t really know how the sim handles icing and how the plane may impact it.
