investigating PFD IAS Frozen in Severe Icing - 1.1.8

[xe_operator]

All IAS indications from the pitot static systems were frozen at 250 during severe icing. All anti-icing systems were on.

So? The icing is severe. Get out of it.

The A350 is capable of operating in severe icing conditions. This is a bug.

Had this happen on approach to CYYZ today. Turn off icing effects from the sim itself seems to have fixed it. I had all the anti-ice on and it still didn’t stop the pitot freezing with IAS stuck at 180

Samething happen to me today, on the approach to CYYZ ILS 24L. IAS froze at 200

Had the same issue on final during my last flight while intercepting the localiser in IMC and icing conditions, freezing the airspeed during deceleration. No ECAM warnings at all, no indications of airspeed disagreement or probe blockage/failure. I guess all probes iced up at the same time, or ECAM warnings simply haven't been implemented yet in the iniBuilds A350 for these types of situations.

Just flew from Newark to Minneapolis ... all perfectly fine until below 10000, then all hell broke loose. Got icing warning, turned on de icing systems, and plane went haywire. Automated systems failed, speed tape showed stalling at 220 kt, and plane wanted to plunge. Had to manually recover and barely made it to runway. Is this the icing bug in action? Never experienced anything like it before. Fenix does NOT do this. 🙂

By the definition of severe icing no aircraft is capable of operating in it, as it renders deicing equipment useless.

Turned pitot and window heat on for a flight from Minneapolis to Toronto -- even though according to Airbus, it's supposed to be automatic (no need to activate it) -- and again crashed on final, in cold but not even icy conditions. Soon as I got to 2500 feet at flaps 2, speed tape went haywire, stall was announced, and plane dropped to ground. Will try again, this time with MSFS 2024 icing set to off, but am also doing a clean uninstall/reinstall, in case this isn't an icing thing. Really wondering if I'm alone with this bug. Thx.

Thanks for report, team is looking into it.

In the meanwhile, recommend setting the Icing Effect under Assistance Options to 'VISUAL ONLY' or 'OFF'.
Thanks!

[AVGA]

Will do. Thank you.
