Hello all, I posted this on the p3d forum but I think I might get some help here as well. Hope copying the same content doesn't offense anyone. I just bought the v3.1 and I liked most aspect of it. However the joystick problem alone is making the simulator very uncomfortable to fly with. Here is what I encountered: The sim is reading "noises" from my yoke and even if I have my hands off the yoke, I can see the "virtual" yoke occasionally shake around its natural position. I tried to calibrate it with both the built in function and FSUIPC, and I can observe the slide jumps like -118, 0, -118, 0, 0, -118 and there's no way I can eliminate this. I tried the "eliminate control peak" function in FSUIPC and it doesn't work either. Also it happens when I turn the yoke left to bank the airplane, the yoke will actually go right first for a tiny bit and then go left, same happens with pitch axis. I have never encountered such problem in p3d v2.5 or FSX, I don't see this noise in the Windows joystick align interface either so it doesn't seem like a hardware problem to me. I'm wondering if someone could point some direction for me to try fix this? (I tried playing around with sensitivity and null range but that won't fix the problem.) Another problem which is minor but maybe related to this, that is when I use mouse look (space+mouse), I can't go 360 degrees but rather something close to 270 which means I can only go from 45-315 and can't reach the nose view of the airplane. Thanks in advance for any help!

Thanks very much for your clear explanation 777simmer and kevinh. I guess that takes out my confusion in theory and I just need to practice more.

You are absolutely right and I'm trying to keep my aircraft trimmed all the time as best as I can. Also thank you for the tip on yoke settings, that's a very useful link! btw, the settings in P3D, except for those graphics related ones, are exactly the same as in FSX. That's interesting, so since you brought up this topic, the "trim by speed" logic is also something that makes me confused. In my understanding, stabilizer trim angle is directly related to speed (in a fixed configuration) in any aircraft and if you don't touch the trim and elevator, the plane will fly at a certain speed when it finally stabilizes itself after some oscillations. So what's special about the 777 system? I looked up in the FCOM but didn't find an answer. Thanks!

Thank you for the reply! The second point is really helpful and it's good to hear that this is realistic. I was worried about this being a software problem before and reinstalled several times as no one seemed to have this problem. About the first one, sorry I didn't describe it clearly, so let me put it shorter here: In the case when your IAS and trim speed vary by a big amount (in the case I described above, the trim speed was almost 100kt lower than IAS).The airplane may behave not as it's supposed to, in my case, it pitches down instead of pitches up and accelerates instead of decelerates. So I'm wondering if it's caused by some aerodynamic factors that I don't know about? ps. About the deadzone, I do have it set for 11 in P3D settings menu. Regards

Hello, When I fly the 777, unlike the 707 I flew, the trim seems a bit sensitive and anti-intuitive to me. Since I'm new to aviation those behaviors that feels strange to me might be perfectly normal and basic but I still want to know why that happened. So here are the scenarios: 1. Once I made a departure, climbed and then reduced the thrust, leveled the plane at 250kt, then the aircraft started to have a tendency to slightly pitch down, accelerate and sink. To prevent this from happening I need to constantly put back pressure on the yoke. Now if I add the throttle a little bit, it won't stop the plane from dropping and I will also begin to build up more speed. So naturally speaking, it's because my trim speed was too high right? But since I haven't moved the trim that much after take off, I decided to confirm this first before I do anything. So I turned on the "show FBW trim speed" and it shows: 160kt while my plane has already accelerated to 270 at that time and still wanted to descend. So well, I did what I had to do, I tried to trim up my plane further, like 4s after the trim speed reached its minimum (the stab trim angle did increase even after trim speed reaches minimum). Then after a short delay, the aircraft started to pitch up tremendously, finally, then I managed to adjust the trim speed back to where my speed was, everything normal after that. 2. When I turn the 777, with less than 30 degrees bank angle (15-25 normally), there should be no need to put back pressure on the yoke as the FBW will trim that for me right? However in the simulator if I don't pull back the yoke in a turn the pitch angle will start to fall after about one second. Actually if I want to hold a leveled-30-degree-turn, I would need to trim up the nose for about 4-6s (which equals to 40-60kt of speed) along with a slight back pressure on the yoke, and then trim down and push the nose when about to exit the turn.
