Took a quick flight with the RealAir Lancair Legacy last night. Loaded the latest version of OPUS FSX weather with bump switched on in the camera DHM settings.

 

On climb-out I engaged the autopilot. All was fine until reaching cruise at around FL80 when the autopilot refused to level off and continued the climb. It also didn't react to any heading change instructions.

 

I switched it off to fly manually when I discovered that the flight dynamics were stuck! The elevators and ailerons were moving (I checked in spot view) but unless I wound on at least 30 degrees of bank it wouldn't react to stick inputs. 

 

This happened with bump and levels 1, 2 or 3. As soon as I switched off bump the aircraft reacted normally. This didn't used to happen but since the program has been updated over the last month or so I always have this problem with nearly every aircraft in FSX.

 

I've tried FS Global Real Weather and don't have the same problem but the OPUS FSX turbulence is IMO more realistic so would rather continue to use that.

 

Will OPUS FSX generate any sort of weather-related turbulence with BUMP switched off?

I found the same thing from beta 3.35 onwards. I asked on the forum and was told it was something to do with pre-ordaine turbulence at airports. I found that a plane wouldn't answer to the helm for quite a while then boom! It turned. This was only turning to base and the again to final. I played with the bump aircraft settings to no avail so I unticked it. All good again.

We did find a problem with the yoke detection cut off which was corrected in Beta Version 3.34.8. The latest OpusFSX Release is Version 3.36.1

 

We test with the RealAir Lancair Legacy and haven't noticed this problem with the autopilot on our system yet with 3DOF enabled, I will conduct some further tests. Have you tried also tuning the associated Delay setting for the DOF?

 

You will get DHM turbulence with Bump Aircraft turned off.

I've got 3.36.1, I'll turn bump aircraft back on and check.

Well. My yoke is still seized by the phantom co-pilot. I've turned off bump aircraft. Still get turbulence but it's not 'manufactured' and predictable.

Hmmm, can't think of any suggestions if Bump Aircraft doesn't work with 1DOF and a Delay set, other than the obvious one of calibrating your yoke and perhaps introducing a dead zone.

 

Cheryl

My yoke is calibrated to death! :biggrin:  OK, I'll try 1DOF and 2 delay (what's DOF? I understand it to mean Degrees of Freedom? :unsure: )

Thought you would be the calibration king!

 

Yes, the DOF Degrees Of Freedom option can be set to 1,2, or 3 as required. These settings are equivalent to turbulent jolts in Bank, Pitch + Bank, and Pitch + Bank + Yaw respectively. You should set an appropriate DOF to suit your preference and capabilities of the aircraft sim. Set the lower value options if your aircraft sim has trouble maintaining a heading.

Set a Delay value if you have problems with jerkiness or the auto pilot in aircraft sims. The Delay factor (0..4 = Fastest to Slowest, default 0) adjusts the Bump Aircraft frequency.

Reporting back.(Are you reading this Traffic?) Tried the aforementioned settings and the co-pilot minded his own business. That was good. However, there were no effects at all, just like turning it off. I'll up the ante a tad.

The Spy window will indicate what strength of turbulence you have at the moment ranging from 0 (none) to 8 (max). Set all defaults in the DHM dialog and start off with DOF 2 trying different Delay Factors (0 is best), use the highest DOF setting that your aircraft is capable of handling.

 

To create a known turbulent condition try Importing a GLOB METAR using a text import file,

Then fly around at about 2000 feet AGL.

 

Stephen :smile:

Ah the Spy window. I forget about the Spy window.  :rolleyes:  Text import files are beyond me I'm afraid. I'm a 'fly what ya got' kinda bloke. All I really ask of Opus is that it gives me the weather 'as it really is'.

I appreciate your help Stephen but don't take up any more of your sun tanning time. Have a Cuba Libre for me. :wink:

Hi Ron,

 

Sorry long busy day at work trying to get people out of traffic jams so only now have the time to visit AVSIM and just seen the replies to the thread. Lots of interesting info from you and Stephen. Much like you this software worked nicely until recently and then I started getting this freezing on all aircraft.

 

I'll try a few of the above settings using the Lancair as the test aircraft this weekend. I already have the METAR text Stephen suggests loading. It is worth trying. It's pretty easy, just copy this:

 

GLOB 040900Z 09024KT 9999 SCT024CB 28/22 Q1028

 

into notepad, save it in your OPUS folder somewhere then go into OPUS click "weather" tab and tick the box at the top right "Import METAR Data From File" then click "Browse" below go to the folder you saved the METAR text file in and open it then click "update weather" at bottom of window. It's very useful for testing out different settings as it produces extremely strong turbulence.

 

Once you've finished testing you just go back into the weather window, untick "Import METAR Data From File" and finally click "update weather" again to get the current live dynamic weather instead.

 

I'll keep an eye on the "spy" window as well this weekend. Forgot about that feature too!

 

EDIT: I noticed we're both using DX10 - I presume that has nothing to do with it...?

 

Regards

 

Adam

Wow! That's a helluva breezy day! Thanks for tutorial Adam. There IS a sweet spot there...somewhere. I've now have 3DOF and 2 on the delay scale. . Can't see that DX10 has anything to do with it.
