Hello all,


not sure if this is a common issue, but suddenly during cruise Managed Speed changed to 210.
I switched to Speed Selected and all was fine again.


What can cause this?


Route was LSZH-KSAN.

Problem started shortlöy after 6230N

We saw this in the past, and believe it was caused by errant weather engine input.  I experienced this on three flights shortly after I transitioned from Europe to the Atlantic ocean (Europe to North America flight), which lead me to believe it was indeed a weather engine issue (I was using ActiveSky).  I haven't seen it in quite some time, and we made some changes to the code in one of the past updates to help mitigate this.


If you can, I recommend updating to P3Dv4.5 HF3, but if you do so please update all three P3D Components.


Let us know if you see this again!

Happened to me as well today around 9 hours inflight on a flight from EDDF to VRMM. Speed dropped down to 110 knots and TOGALK activated. I was not able to fix the issue and had to go for Manual speed. I have P3Dv4.5 HF3 installed and active sky . The issue seems to be similar with a former bug that I had with the A320 family.
