investigating Angle of attack indicator stuck

[ECTAE]

While attempting to perform a best-rate turn at 900 km/h, the AOA indicator became stuck after a few turns, resulting in loss of valid AOA readings resulting in the loss of angle-of-attack limit protection. Is this a modeled feature or a system malfunction? I was unable to find any reference regarding operational limitations in the manual.

OAT=-2ºc so its not very cold.

Is that with pitot heat engaged?

[ECTAE]

Yes sir

Hello,

I experience the same issue on a test mission I made. I suspect temperature playing a role in that, it was -2°C and a few minutes after take off, the AoA needle freeze anytime I played it.
I change meteo to 15°C and the problem disappeared. Everytime played with pitot heat on of course.

[ECTAE]

Yes AOA vane freeze is a real thing but I doubt the Mikoyan design bureau didn't take into account the operating temperature on the Mig29. With a stuck AOA sensor, you're not able to perform high AOA turns, best rate turn, and also AFCS protections stop working.

I've experienced the same in the Instant Action, cold and dark flight.

I have also experienced this, but only after I forgot to turn on pitot heat. I’ll see if I can see it again with it turned on.

Yup experienced this on MP servers in cold weather conditions on Caucases, both in under hot and cold start settings. Makes for annoying landings considering the drifty wheel physics of the Fulcrum.

I can confirm this too. It's been like this since the very beginning, and sometimes AoA just doesn't work. I have no idea what's causing it yet.

I saw this once - forgot to save the track; I just assumed a stray bullet was the cause.

[ECTAE]

Nope, and still happening. They don't need any more track. Only using their own module. If you takeoff and do some turns you'll see by yourself. This plane is kind of a mess right now. Every update you got a surpise.

Yes and it happens in the default hot start IA missions too.
