AP disconnect on ILS finals

Manrucavia

I made 2 flights since latest update. One with F70 and one with F100. On both I used an ILS approach, and on both approaches the AP suddenly disconnected while on final. I have checked for any key binding issues but didnt find anything. Both disconnects occurred more or less at the same stage of the approach I believe, around the time the flaps 42 callout came and I was selecting full flaps.

Anybody else had this? Is there any particular limitation for AP use om approach? Or is that a bug or what could have triggered that? Any advise would be appreciated, many thanks !

I'm not aware of any bugs, new or old, that'd be causing this. The only thing that comes to mind is the trim disconnect if sustained stab/elevator trim inputs by the pilot are detected, but presumably you aren't making any trim inputs?

I was flying the RNP Y approach for RWY 06 into Vitória (SBVT) today. Right in the middle of the procedure, the autopilot suddenly disconnected completely on its own, without any input from my end. Immediately following this uncommanded disconnect, the aircraft aggressively pitched down into a severe nose dive.

We are already aware of the pitch-down tendency when manually disconnecting the AP for landing, but having the autopilot drop out uncommanded and instantly throw the nose down during an RNP procedure is a critical failure...

I caught this specific behavior on video, and you may watch it here: https://www.youtube.com/watch?v=UhpcDVPt8Ak

Was just on Approach into Inverness and the A/P disconnected for me in the exact same way on short finals.

No conflicts and not touching the yoke when this occurred.

I had similar on my flight earlier to Manchester ILS 05R approach. Sudden disconnect of the autopilot.

i'm also getting this issue on multiples airports. I tried disconnecting all of my yokes and remaining only with mouse and keyboard and the issue remained

I had this happen as well just now. EIDW to EGCC. Also ILS 05R. On 4nm final the autopilot simply disconnected and putted me down into a dive. Never seen this before the latest update

Hi all. We are investigating this urgently now and will issue a fix ASAP.

Hi all. As we aren't guaranteed to be able to reproduce the issue here, and didn't encounter it during our v1.2 pre-release testing, it'd be great if some of you could try this updated WASM gauge to see if it helps:

The WASM, which has MSFS 2020 and 2024 versions, needs to replace the existing one that is found in: \justflight-aircraft-f100\SimObjects\Airplanes\Just Flight Fokker F100 Airstairs Small\panel
\justflight-aircraft-f70\SimObjects\Airplanes\Just Flight Fokker F70\panel\

Thanks for your feedback and assistance, and apologies for the inconvenience.
