PMDG Forum Rules

1) SIGN YOUR POSTS. Since 1997, we have asked users to sign their real name, first and last, to all posts in the PMDG forum. We do this in order to keep conversations personal and familiar. You took the time to be here, we want to get to know you. This is one of the few rigid rules that we enforce regularly. We do so because we feel that forums in which users must engage one another personally are generally warmer, more collegial and friendly. Posts that are unsigned will be quietly removed without comment by the moderators, so to make your life easy- we recommend enabling your forum signature so that you never need to remember. Do this by clicking the username pull-down at the top right, then selecting "User Settings." You will find the signature editor on the ACCOUNT tab, about half way down the page. Look for "Edit Post Signature." Be sure to click the "Show Signatures" box.

2) BE NICE. We are all simmers here and no matter our differences of opinion, we share a common love of aviation, computing and simulation. Treat everyone else in the forum with respect even when you disagree. If someone frustrates you, walk away from the conversation or ask for a moderator to get involved. Speaking of Moderators, they prefer not to be treated as "The Thought Police" but if any behavior infringes on the enjoyment of another user or is otherwise considered to be unacceptable in the moderator's judgment, it will be addressed in keeping with our view of ensuring that this forum remains a healthy environment for all simmers.

3) BE LAWFUL: Any behavior that infringes upon the law, such as discussion or solicitation of piracy, threats, intimidation or abuse will be handled unsympathetically by the moderators. Threats and intimidation may, at the moderator's discretion, be provided to law enforcement for handling.

4) BE FACTUAL: When you post, always be factual. Moderators will remove posts that are determined not to be factually accurate.

5) RESPECT COPYRIGHTS: Posting of copyrighted material such as flight manuals owned by Boeing or various airlines is not allowed in this forum. If you have questions related to copyrighted material, please contact a forum moderator for clarification.

6) RESPECT PMDG: We love to hear what you like about our products. We also like to hear what you think can be improved, or what isn't working. Please do tell us and we will always treat your feedback with value. Just be sure to treat the team respectfully, as they do put a significant amount of effort into building and maintaining these great simulation products for you.

7) RESPECT PMDG DEVELOPERS: All of the developers will spend some time here. Given the ratio of developers-to-users, it simply isn't possible for us to answer every post and private message individually. Please know that we do try to read everything, but developer workload is simply too high to manage personal contact with tens-of-thousands of users simultaneously. In most cases, members of the development team will stick to conversations in the forum and will not answer private messages.

8) RESPECT OTHER DEVELOPERS: PMDG has always advocated for a strong development community and we have many friends within this community. Every developer offers something unique that helps to make the simming community larger and more vibrant. We insist that you treat our friends respectfully.

9) RESPECT MODERATORS: Moderators have a tough job, and none of them enjoy having to stomp out negativity. If a moderator has to weigh in to keep a thread peaceful, please respect that effort and refrain from giving the moderator any grief.

10) If you require official support for any of our products please open a support ticket through the support portal, https://support.precisionmanuals.com

11) This forum is designed primarily as a vehicle for the PMDG development team to interact with our customers, and for customers to interact with one another in a manner that is positive, supportive and assists in the general advancement of understanding the simulation and helping to make this and future simulations better. Any other use of this forum is not permitted, including but not limited to discussion of pricing policies, business practices, forum moderating policies, advertising of non-PMDG products, promotion of events, services or products that are not approved in advance by PMDG or any other topic deemed unacceptable by any forum administrator

    Aircraft veering left on the ground

    Hi Guys. I have a really irritating issue where my aircraft veers off the runway or anywhere on the ground. Taking off is ok but landing can be a right pain and sometimes when trying to correct it spins out. It varies from aircraft to aircraft but its the worst on the A310, PMDG 737 and twin otter.

    I have a Thrustmaster Airbus TCA and also an older stick which the same thing happens on also. Both are calibrated and working perfectly and it behaves perfect in the air.

    Even the wheel light stays forward on the PMDG 737 but yet moves off to the left when i start moving. I have even uninstalled and re installed MSFS. I thought it may have been an issue with the non powered USB hub but i plugged them in directly to the PC and same thing happens.

    I have adjusted sensitivity and null zones etc and nothing seems to make any bit of an impact.

    Has anyone had this issue?

    Check all you controls if there is a mapping for rudder or steering.
    This looks like an other mapping is conflicting and always steers to the left.

      Also please check if Flight Model is set to Modern and all Assistance Options are Off (As real), especialy pilot and ground assistances.

        Checked all that and it was all off. the only thing that was on was helicopter auto rudder.

        Strangely after i changed that the 737 and A310 took off normally but when i shut down to re-install the Twin Otter i went back to 737 and it started happening again.

        Flight model is modern also. Im baffled as when i start moving its veering straight away

          I am not familiar with your controller.... is it a joystick with a twist axis you use for rudder? How do you control rudder and what do you have assigned and sensitivities set? Basically, answer Rene's post # 2 above.

            I can’t see any irregular bindings. I have a Thrustmaster Airbus TCA with indeed the twist for rudder. Same on the older yoke I have for flying dingle engine props.

            I had a CTD the other day and I started in safe mode and took off on the A310 and A320 and that’s when it behaved perfectly. I just remembered that’s what it was. Now I assumed the default bindings were reinstated after I re installed but I don’t think they were. Is it safe to assume that they did use 100% factory settings when in safe mode?

              Do you use Toolbar pushback? I have the same problem after pushing back. But it gets fixed if i use rudder after that

                Someone on the MSFS forums reported a similar issue when flying from a particular airport (FlyTampa’s Toronto, I think?). They ultimate uninstalled and reinstalled the airport and their problem was resolved.

                So it might be useful to see if the problem occurs everywhere or only at specific locations.

                    Have you also checked your brake bindings?

                      Is there something for left and right breaks? I have only ever come across one for breaks in general.

                      Also, is there a way of starting in safe mode intentionally? I need to check again to see was it safe mode that the aircraft behaved normally.

                        Most aircraft have left and right toe brakes so yes there are mappings for both.

                          Hi, I have exactly the same problem with my TCA Stick and rudder, I tested this in extenso (I have been a beta tester for a payware 737 for years, so reasonable aware of testing set-ups, calibrating and tuning hardware, result analysis, debugging etc.), and it is not (at least in my set-up):
                          • Asymmetric trust
                          • Other rudder/jaw bindings
                          • Asymmetric brakes
                          • Wrong trim settings
                          • Weather related
                          • Limited to a few airports – it happens at every airport
                          • Day/time related
                          • Roll instability
                          • Uncalibrated hardware
                          • Etc.
                          • Etc.

                          I had my TCA Stick and rudder replaced by another complete set from TCA (thanks very much for their support), so not likely hardware related.

                          It happens to all airplanes in msfs, as well in X-plane 12, and interestingly the earlier beta versions of x-plane 12 worked well.

                          My OS is Windows11, but the same happened with Windows 10.

                            ​Am I reading this wrong? If it happens in all aircraft in MSFS, how did you conclude it’s not in your setup somewhere?

                              Check your axis again. My Thrustmaster T16000m tended a bit to the left in the aileron axis and to the right of the twist grip. Not really a spike but rather a mechanical null zone and a hyper sensitive encoder. Cheap quality… I don‘t know the Airbus TCA but it doesn‘t have hall effect sensors, does it?

                                assign a dead zone for your rudder and / or tiller axis and see if that solves the problem.

                                  I've had this with the Thrustmaster Airbus TCA along with the "twitchy" rudder problem. Fixed the latter using the following video which has also made the former way way less of an issue outside of strong cross winds...



                                  Few minute fix that has made using the controller so much more stable.

                                    problem is, its happening on both of my sticks so seriously doubt its hardware.

                                    As i said, it didnt happen in safe mode which i assume uses factory setting bindings?

                                      Why assume? Go into your Controls settings and check.

                                        Well i totally reset all controls and that didnt work on either controller. and then i got it to start in safe mode and that didnt work either so im at a loss!

                                        Ive tried every scenario with both controllers and if im honest it only seems to be getting worse. the 737 was nearly 45 degrees off the center line last night and once in the air it was perfect.

                                          Are you absolutely certain there's no failure of the aircraft? Check the FMC for failures and items needing service (brakes, tires, hydraulics ..). Are you certain you don't have any Assistance options enabled in the sim? Are you certain you don't have any controller keybind conflicts with your brakes (and yes, Left and Right brakes can be assigned independently)?

                                            Yeah all checked. also cleared bindings for left and right break and kept it just just the break. Its happening on every aircraft but its way more invasive on the A310 and B737.

                                            At the end of my tether now with it. It seems like it goes straight for 6-7 seconds then heads off to the left then.

                                            What about nose wheel steering axis?

                                            Also, if i dont use any hardware it veers to the left also!!! Throttle and Yoke plugged out.........

                                              Probably not the kind of answer you will like, but...

                                              ...you won't find a single 737 that'll constantly go straight no matter what in real life under real operating conditions either.
                                              Pilots will constantly have to correct for several factors, including amongst others wind, left/right slope of taxiways, the plane not being perfect (aka having slightly more or less drag on one side than the other).

                                              Thus it is normal that you have to constantly correct your taxi route.

                                                ...you won't find a single 737 that'll constantly go straight no matter what in real life under real operating conditions either.
                                                Pilots will constantly have to correct for several factors, including amongst others wind, left/right slope of taxiways, the plane not being perfect (aka having slightly more or less drag on one side than the other).

                                                Thus it is normal that you have to constantly correct your taxi route.

                                                Ya i completely get that but i had to have the rudder fully to the right to go any but straight.

                                                Ive turned Auto Rudder on and it seems to have fixed it but thats surely just a plaster on the wound?

                                                  It just might be something wrong with the potentiometer in the rudder axis. I have the Thrustmaster T16000M and my aircraft are always veering to the left or right with no input, even if the winds are calm or I'm taxiing at a slow speed. I have no idea how to fix it. Recently I got the Honeycomb bravo and alpha with logitech rudder pedals. I still get that weird yaw/uncontrolled movements at any speed and condition. Don't know how to fix it.

                                                    Hi, I've had this issue and am still getting it on occasion. I have the Thrustmaster TCA and from my research I think there is a common issue with the rudder axis. There are a lot of videos on how to fix it but I've had to do it several times already as the wiring moves out of place again over time. Is it to the same side for you?
                                                    Might be worth having a look into the sensitivity settings and look if there is movement, de-activating the axis entirely if using pedals (wouldn't work as tiller then) or increasing the deadzone.

                                                    Hope this helps.

                                                      Ive seen it too but im 100% certain its nothing to do with that?

                                                      Just weird that once last week there was no issue. Plus it happens in my older stick too. I turned on Auto Rudder and its helped a bit but i know the way its going that its just helping but not the fix.

                                                      Is your auto rudder on?

                                                        No auto rudder is off. I had literally just started to think about potential fixes again yesterday other than opening upp the TCA again. I might have to just go back to nosewheel steering via pedals and deactivate the TCA axis entirely. I thought initially that it might be due to wind so countersteering seemed legit but the way the wheel and the tiller in the cokpit are twitching it can't be that.

                                                      Whats everyones stance on auto rudder? its improved it majorly but there is still a slight pull but its very flyable now. Taking off was a job but landing was impossible before.

                                                        The PMDG stance on auto rudder is OFF.... see Introduction document pg 26. All PMDG products in all platforms has always recommended auto rudder be set off.
