won't hold flight path at cruise

Recommended Posts

Every so often I'm getting really weird behaviour at cruise. This is primarily in PMDG 737 and 747 (because that's primarily what i fly) and happens in cruise. Everything will be normal and then the aircraft starts turning sharply left and right and can't seem to stay on the course. Resetting the AP doesn't help. If I disable live weather and then clear all weather using opus, then exit and restart opus and restart live weather it works fine. I'm running version 3.55.1. Thanks in advance.

Turn off all Bump Aircraft options in your DHM settings, either in all General DHM or in all Live Camera views for those (or all) aircraft types.

That helps but it is still happening. I'll get the "swerving" and then I turn off live weather, clear the weather, exit Opus, then restart Opus, activate live weather, then it's fine. 

 

Edit: I turned off the bump options in DHM settings.

Provided you turn off all Bump Aircraft options in all DHM dialogs OpusFSI won't be affecting the aircraft directly at all. You should also enable wind smoothing and enable Dynamic Wind Control DWC in the weather options. DWC requires fsuipc4 to be installed and active.

I found out that its the wingflex with the PMDG 737 NGX. This is causing the plane to turn extreme.

Set winglex to zero and the problem is gone. DHM can be set normaly.

Turn wingflex data off in OpusFSI or better still turn it down. Only if you have a problem with the 'in sim' reaction to wing flex turbulent data though.
