High altitude shakes

Recommended Posts

At high altitude (plus 20k feet) my 737 commences to tremble or vibrate.

 

Inside the cockpit all is smooth, but looking from the cockpit to the horizon the shaking is very noticeable.

 

Any suggestion on a solution?

Try a flight without Opus and report back.

Flew SLC to DEN @ 33k feet without Opus wx.

 

PMDG 737 started tremble @ 24k' and continued as usual.

 

Starting playing with an add-on, AccuFeel. 

 

Determined setting Vne (max IAS) = 0 causes tremble to return to smooth!

 

Problem solved.

AccuFeel is designed more for products that don't have the amount of realism that ours have. As an example, you can use AccuFeel to add in all kinds of realism feel to even the default aircraft. It's best not to use it on our aircraft, which already have realistic dynamics. Trying to add "realism" on top of realism is going to make the aircraft behave oddly, as you've seen.

 

Additionally, be careful with Opus. From what I recall, it has or had an issue with upper altitude wind.
