P3D V4 Rocking up and down

Recommended Posts

I am having problems with the P3d V4 777.  I continually get rocking (slight up pitch and then down pitch) while flying with AP on VNAV and LNAV at 31000.  This is the 4th flight same thing.   Can anyone help me that has experienced this.  I noticed that happened in 2013 a lot.  I can't find anything on this in the forum.  I do appreciate the help.

Update:

Bounces between 30000 and 32000 can stay at Alt set of 31000.   Tried to unplug joysticks still continued to rock, No weather loaded, No trim axis assigned to joysticks.

Do you have FSUIPC installed? If so try moving the FSUIPC.ini file out of your Modules folder

Please list out anything and everything that you are using on your computer, sim-related.

Additionally:

What anti-virus program are you using? What kind of motherboard?

When it comes to asking for support, it's usually best to bury us in as much information as possible. Playing 20 questions about it delays things and makes it more difficult than it needs to be.

All,

    I have gone back to the tutorial flight.  Flew it just as specified.  It almost killed me :)   But the PMDG 777LRX flies perfectly smooth.  I now wonder what step I left off that caused the effect I am seeing

Were you using time acceleration before or in smooth flight? I don't see how that would stop it bouncing.

 Chris...No idea but I was not using time acceleration.   Also, I stopped P3D reloaded the tutorial flight from scratch so it was a completely new environment....It is either the aircraft configuration (I downloaded repaints only from the PMDG Operations Center) or something I missed in start-up or flight planning.  I want to recreate so that I can understand and then share with everyone...

Were you loading the default panel startup configuration in your "rocking" flights or was it a custom made one?

I though that I am the only one who has this issue, because not so many people have this issue, I do not really ask in this forum,  so far I just stop flying with 777.

Seeing the porpoising as well with latest build. This is on P3D v3. 4. Hundreds of hours in her and first I've seen of this. This was with the 300ER

Gents,

Earlier, I asked a few questions. Instead of "oh hey +1" or "me too," if you want any meaningful help, or really want to assert it's an actual problem you're going to have to help us track the issue down. I don't have access to your computers, which is why I asked the questions I did. Please answer them:

Without answers to stuff like this, I'm shooting in the dark, and I'm a little busy to be trying to drag answers out of you. Help me (and others) help you.

A/V = ESET Nod 32. All FS related items excluded from scanning and disabled while flying. Same one I have been using before the issue cropped up. 

Motherboard = AS Rock Z170 OC Formula 

Using: AS16 with ASCA, vPilot, VA Interface from Virtual Avionics, Track IR, LINDA with VRinsight MCP2, PFC Jetliner 737 Yoke with rudder pedals and toe brakes, JetMax 737 throttle quadrant with tiller.

Too add, did not see this whilst in cruise. I selected a lower cruise level, from FL360 to FL280 while in VNAV (dialed in the altitude in the MCP, selected FL280 in the CRZ page of the FMC and hit execute). Upon reaching FL280 is when it started. When I went lower on the arrival I selected V/S after dialing in the lower altitude in the MCP and upon reaching 17000 it did not do it.

Kyle,

    Since I started this thread and I have been doing my own troubleshooting.  My assumption is I did something wrong.  Since when I follow the checklist exactly as defined, I can not recreate the problem.   So my recommendation for anyone that is having this problem is to follow the checklist exactly!   Since I have done that it has worked flawlessly.  

Lastly, what I believe is the cause is one of three things.  1. Using a Cold and Dark Panel (no mods), 2. Either I hit activate flight plan before the flight plan is complete or 3. I failed to properly input the trim before leaving the ground.   These are the only three things that I could have messed up. When I use the default model when it starts and follows the checklist no problems.   I have not tried to see if I could break it again because I am enjoying flying this wonderful airplane...Thank you PMDG.   I have read many times the importance to read the manuals, however, I am impatient and sometimes try to do it my way...

Gigabyte GA-Z170MX-Gaming 5 (rev. 1.1) , Intel I7 6700, MS Defender Anti Virus (TUrned off during installs), Orbx (all regions), FS Dream Team, Fly Tampa etc, AS16, ASCA, Logitech G970 throttle, pedals and Joystick.

I have had a Hash crash but I believe that could be connected to weather...Can't recreate that either.   As a software engineer what Kyle is saying is critical.  He needs to be able to recreate the problem in order to fix it. 

Hope this helps

Not seeing this either anymore. Must have been a one off that the HID initiated. Consider this topic closed.
