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.

    [02NOV22] PMDG 737 for MSFS: New Updates Released

    Captains,

    As detailed over the weekend, we have just released the latest series of updates for the PMDG 737 for Microsoft Flight Simulator.

    This marks the tenth round of updates since the product line's initial launch back on 09MAY22, which means we are averaging a new product update for the 737 about every 18 days. Overall that is a pretty decent update rate- and we anticipate quite a few more as we are bringing new features and capabilities into the product line during testing of the 737-900 and development of the 777.

    This update has some modest changes baked in, but is really focused on control law and improving the overall stability of the 737 within the MSFS environment.

    One of the things that is REALLY hard to accomplish in simulation at any level is a realistic model of fluidity, pressure, stability and instability in the atmospheric model. The influence that all of these factors have on the stability of an aircraft in flight has been a holy-grail in mathematical simulation since the advent of the first flight simulators- and even the much-revered training simulators that so many of us train and retrain in each year fail to do it well enough to be convincing to a pilot with even modest experience.

    One of the things we take great pride in at PMDG is our ability to adapt our work so that it yields accurate results within the simulated environment. This is not a simple task and takes many iterations of change, lots of testing and heaping portions of patience- especially in a simulation platform that is changing even as we work. What we have focused on during the past few months is to improve the core capability of our MSFS product line to allow the airplane's control law logic to manage atmospheric instability gracefully without making itself obvious to the user. Most sim pilots are completely unaware that their PMDG products for the past 17 years have been "fly-by-software" with a very complicated computational process leveraging the capabilities of the simulator in order to yield appropriate results.

    This core logic required a huge update to deal with the far-more-dynamic environment of MSFS when compared, say, to P3D. It has taken some time- but we have made significant progress with it lately- and this update brings us much closer to where we want the package to be.

    The MSFS environment modeling is excellent in very many regards- but it also provides some levels of mathematical instability that would be truly terrifying if you hit them in real life. We have adapted the 737 to manage these moments so that they are not disruptive to the flying experience and still yield a realistic result. This required a comprehensive re-study of the control logic used in the actual airplane, with adaptation for extremes. It has been a fantastic exercise and we think you will notice the results right away as improved stability in roll, pitch and now also in the thrust channel.

    That isn't to say you can't find scenarios in the environment that won't cause some instability for the airplane- but it is capable of flying through them and returning the airplane properly to stability without excessive distortion provided that the unrealistic disturbances are momentary and not continuous. (We fond some spots where it is possible to see the airplane go from -0.3 to +1.5g in the span of milliseconds- which if you experienced in real life would convince you that perhaps travel by train is a much saner option for soft, plump humans. )

    One of the nice aspects of this work is that it is entirely dynamic, so changes to the MSFS atmosphere shouldn't upend the system, theoretically. (Although: we haven't seen how thermals are being implemented yet... they are due out next week? We shall see...)

    In other fixes we included a few sweep-up details, but we are mostly focused on the 900 and tablet implementation. The tablet goes into testing this week, and the 900 probably a week from Friday...

    Stay tuned here for more information. Things are progressing nicely- and we very much appreciate your participation in the community!

    One note of caution: We are all watching the SU11 timeline, and we are comfortable that the 737 is compatible with the beta version we are currently testing. By "compatible" we mean that it runs normally and behaves as expected. The SU11 SDK is not yet capable of exporting a C++/WASM project and we are eagerly awaiting the next SDK update so that we can look at fixing/updating some of the behaviors reported to be unlocked per the SU11 SDK. (active pause, for example...) We are all standing by to dive into any emergency fixes that might appear once the final SU11 lands- if necessary.

                Rob i like what have youve done with everything. You know I've been.here since the first release of the NGX in FSX.. what are the chances of adding a more dynamic realistic approach to.weights for seasons for adult weights and bags. It matters considerably the weights implemented are wayyyyy below the FAA new seasons weights coded into the aircraft. Non standard weights, zone counts and FAA. EASA seasonal weights should be accountable for.

                Would love to hear back

                  Great news, just a question, will you roll out these stability improvements to the DC6 ? are they needed?

                    Gonazalo- I think there is a popular misconception that a 1950 build gyro using 1950s actuators is somehow supposed to provide the same level of stability as a modern, triple channel, IRS/ADC guided, fully redundant flight control system. It shouldn't. I have flown a gyropilot from the 50s and they are really designed to reduce pilot workload- but they won't fly the airplane well for you in all but the simplest of conditions. Most of the grey-gulls i've talked with about that era will tell you they hardly used the things unless it was severe clear and absolutely calm- else the oscillations would annoy the pilots, roll the stews around and make the passengers nauseated. So- no... we won't be putting a fully fly-by-software control system into a 1950s airliner. It doesn't need it. LOL - RSR

                  I would say that it is specifically for those not running the SU11 Beta. As far as I know it is still PMDG's position that the SU11 Beta is not recommended.

                    Daniel- I wouldn't say "not recommended" but more "exercise mild caution, just in case." We were able to tamp down a few loose edges that improved stability in SU11... we are awaiting further updates to that one so we can continue. - RSR

                      Sounds like a very good update.

                      I'm in the middle of upgrading my PC, so I won't be able to try out the new update until tomorrow night.

                      Just wondering what everyone's opinion of it is, for those who have tried it. How is stability, in particular during approach?

                        Tried this update today. I must say, I'm really enjoying how smooth the FD and N1 Indications are. The general "feel" of the aircraft is such a joy to experience. Really appreciate the dedication the PMDG has put toward these updates.

                        One additional thing I've noticed (dare I say?), The wing bounce\flex animation through the various stages of my climb was phenomenal! Not sure if it was this smooth before, but the animation is definitely more "precise", which is the only way I can explain it.

                        Looking forward to the 900 and EFB!

                                          Do you use FSrealistic?

                                            No, I don't use any additional besides AIG Traffic Controller. I will do another check without using AIGround and AIFlow, 2 programs that control AI flow via SimConnect - don't know if that could be related in any way. Thank you!

                                          I took a video today, you can see the problem very well.

                                          I have tested it with and without FSRealistic.

                                          Also I have removed all MOD's. But here it is probably a problem of the A/T from the PMDG since the update yesterday.

                                            I have the same issue with the AT it's all over the place trying to maintain the proper speed mostly in the decent on a STAR and while maneuvering in the terminal area at all different flap configurations and speeds.

                                            Hi Matt! What I do, is carry some extra fuel and place the plane in a HOLD Pattern, for as long as it takes to clean the table, wash the dishes and get the coffee ready for the final approach...

                                            BAIRES, concur and can attest. It does not work for when after all that you're just too tired to finish it up that night and I leave it for the next!

                                            Great to see these updates and improvements coming Robert!

                                            One thing I'm hoping for whenever a new update is released is being able to use the RECALL button in VR.

                                            I've filed a ticket for this back in May but apparently, no one on your side is seeing the same problem. Which is truly odd when both myself as well as others in here have this issue. I even replaced my VR headset with a totally different one since first submitting the support ticket and still see the same issue. I also replaced my motherboard, CPU and GPU during this time. Meaning I also have a 100% fresh installation of both Windows, MSFS and your 737. Still, I see the very same issue not being able to press the RECALL button in VR. My current headset is the Varjo Aero. Meaning no WMR headset. So it can be ruled out it's a WMR issue.

                                            As you know, being able to use the RECALL button is quite vital if you want to fly realistically. When you're as in my case spending all time in VR (which by the way is absolutely amazing in the 737 with all the crisp textures, the spot-on lighting etc!), not being able to press the RECALL button is quite annoying to say the least. I also don't get what is so special with this single button. Given how all other buttons, knobs etc in the cockpit are working just fine.

                                            I realize this isn't a big prio for you where the majority of your customers still fly in 2D. Still, I hope we'll one day see this issue properly investigated and addressed. Now when those of us flying in VR and having this issue have patiently been waiting for a fix for the last 5-6 months.

                                            Cheers!
