Dan, thanks for your help

I just purchased and installed 747 for P3Dv4 with out any incident. Then , I opened P3Dv4 I received the following "Warning" : "Cannot get product version-data-string not found" I clicked "OK" then all was normal. Fs2Crew performed with out any problem. What is this "Warning" How can I fix it. Thanks

Thanks to All, I made a test flight KEWR-KDEN with out any incident. I will make two additional Test Flight, then I will close the case, WOW

Marc, I turned down all sliders 20-30%. Enhanced Turbulence box is not checked. I calibrated all controls. Now I will make a test flight. Thanks

Dan, I didn't ignored, I appreciated your effort trying to give me guidence. As I said before. My problems are nothing to do with Turbulence. 99% A/P disconnect flights were turbulence free. I will try to fix it. If i cannot.then will open PMDG Support ticket Thanks

Dan, That is time first time I opened AS wind settings. They are all default settings. I will read Pg92 and will check zone settings. Majority of my 777 with good weather and no turbulence. Today only I encounter with heavy turbulence over KORD and A/P disconnected. That was the turbulence effect. Rest of my all disconnected flights happened during beautiful weather and no turbulence. 777 P3D V4 I didnt read yet, but I will read it. Thanks for the info

I am going to check each items. Will inform 1-I am wondering if there is a problem with some hardware or controller,causing a spike. Will it not be influence to other airplanes (747,737, DC-6 and others. THey are all OK) 2-What kind problem can effect only to 777? Thanks

Lars, Thanks for your response.. "Also, go to the key commands section via the CDU and check which commands are mapped to A/P " How shall I do via the CDU?

Unfortunately, my test flight KEWR-KDEN failed. 1-After I uninstall and reinstall 777-200 and calibrated all controls, no weather effects 777 take off from KEWR. At 2000 Ft I connected A/P . Before reach at 6000 Ft A/P no reason disconnected. 2-I reengaged the A/P but at 5000 ft again A/P disconnected. 3-Climbing FL380 at FL290 A/P diconnected 4- 224 Nm to Denver A/P again disconnected VS reached -4200. I connected A/P and climb back to FL380. 10 second later 777 A/P disconnected and dived VS-4500 ft. I terminated flight. I am totally lost I never see this kind strange problem with 777-200. I wish I can find if I am causing this events or 777.

REX provides clouds settings and Active Sky Engine receives Real weather data/winds and develops weather for P3D.

I followed Gregg and J35OE advise. Reduced the Elevator Trim repeat rate by 50% from 64%. It gave me control back. Thanks all.

Thanks for your responses. My problem: During level flight, as soon as I disconnect the A/P. Plane goes up/down rapidly no way you can trim the plane. I have various airplanes, none of them has this problem Is it possible some AXIS in puts causing these problems. I have CH Eclipse yoke and CH pro pedals.I calibrated it recently. I will make test flight with various payload and calculate the take-off trim accordingly.

Last week I purchased PA31 Chieftain. I made some flights with A/P. No incident. If I fly by hand. There is no way I can hold the plane's altitude. It is up or down. No time even put proper trim to avoid this kind flying. Some thing is wrong, if you memebers having no problem by hand flying, then problem must be from my side. What causing this problem ? How can I correct the proper inputs to plane's controls.

Installation was successful. I will make a test flight tomorrow. KEWR-KDEN will follow the same route of A/P disconnect problem. I have only have Active Sky Engine.Weather provided by REX.

Dan, "you never provided information on type of weather you are using" Active Sky P3Dv4" Weather was perfect and clear. Unfortunately I already uninstall and reinstalled 777

May be it helps. I will uninstall 777. Clear all files and reinstall it.

Marc, I don't have Kaspersky. Good advsie, I will not put mobile phone near my PC. Thanks

Dan, I checked all Axis. Settings are correct. There are no conflicts. Lars thanks for your post. That is the same incident is happening to me. Romain, tonight I made two test fights with out any A/P disconnect problems. I don't know what to say any more. I will continue make test flights. Will inform.

I am sure that is not Bug. I agree with you. It is possible some configuration problem. I will try to find it. Thanks for your help.

This happening only with 777. 747 is ok. Today's flight from KEWR-KORD all was ok , until plane approaching Decent Point (I was not checking PC) When I back to PC I found 777 at the departure gate with out landings gears. Weather was no issue.

Dan Hi, Lately I am experiencing problem with 777-200. A/P keep disconnecting during the decent. I am trying to find what is causing these events, May be there is some logs in PMDG Error file, but I cannot located it.

Where is PMDG 777 Error Log file located in P3d V4 ? Thanks

Marc, "third axes set to your flight control axes like for example an x box controller." I have P3Dv4. I opened Option>Control" screen I cannot find "flight Control" axes. I dont find any axes assigned to "Mouse Yoke" or Mouse Look" sections,

Romain, thanks for your response. I will check them,
