Flying the 777 from Athens to KJFK today and just south of St Johns, the sim started the most ridiculous turbulence - every 2 seconds the autopilot disengages.  This has gone on for about 45 mins so I'm hand flying it so I have better control over the violent shifts  - the autopilot is useless here.  .  But not sure if i'm wasting my time.   I have turbulence set to Low in the Piloting options.      Really massive updrafts, constantly every 3 seconds for 45 min - so far.  This must be more to do with a glitch in the Asobo weather system than it has to do with actual turbulence.   A look at the CAT map on Windy shows nothing remarkable for this area.  Anyone else had this before?

Looks like it is associated with the jetstream. Just looked at my jepps from work, and it looks like the core of the bad ride is a bit north of St. Johns, but glad to hear there’s at least some turbulence. 

You should take note of the wind values, direction/speed/shift, because it could well be CAT...

I had this the other day.  Sorry I dont remember the exact location except it was over mountains.

I had to go to a preset.  I'll pay more attention next time.

Wind wasn't remarkable.  Slight headwind, 12 knts

Hmmmm, then that's strange (???)

If it was due to jetstream, you should get significant wind values indeed...

Using realistic setting in MSFS with the combination with real turbulence 3d party app 🙂 never had a disconnect and the 777 at 4x rock stable over the Atlantic...
Just arrived from KJFK > EHAM KL644... Was a great jetstream and tailwind 😍

Update:  This wasn't turbulence at all.  It was actually a controller conflict.....

The strange thing is,  I have had 2 controllers connected for about a year.  One for Airbus, one for Boeing.  They have never conflicted with each other.  After tearing my hair out with these ridiculous oscillations (what appeared to be massive updrafts) I decided to have a look at what the EFIS flight control page was doing every time this happened.  I noticed that the elevators themselves were rapidly pitching upwards every few seconds even though there was no physical deflection on the Airbus controller.  I disconnected the controller and no more nonsense.  Continued to JFK. 

Well, I'm sure you're happy now 😄
