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,

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

12) HAVE FUN: This is the whole point of it all.

    [05FEB22] Development Update: PMDG 737 for MSFS


    As we wrap up this week of development on the PMDG 737 for Microsoft Flight Simulator, I wanted to share a progress update to give you an idea where we are and how things are going.

    This week's primary focus fell into a couple of areas:
    • Continued refinement of the Heads Up Guidance System
    • Continued work on the flight model
    • Further refinement of autoflight control laws
    • Refinement of the AFDS Control Wheel Steering mode (aka: How to fly your 737 like an airbus )
    • Problem solving on some issues related to external model textures and the aircraft structure/window interface
    • Continued work on fine scale details within the cockpit.
    • Chasing down compiler-related code issues.
    • The endless game of debugging complex systems.
    The airplane is now being flown on complete flight stages as we continue to look for issues hiding in the background. The systems logic is well in place and the issues being identified are getting resolved one at a time. From a simulation standpoint the software is incredibly stable and well mannered so we are in the process chasing down things that I would call "platform interface" issues. For example, making certain that various keyboard shortcuts and MSFS native commands are connected properly to the software so that the airplane's systems respond appropriately to the MSFS control set. It sounds rather obvious to say that we have to go through all of these- but it is actually quite tedious and requires a bunch of minor changes to the code in order to get things behaving properly.

    One big change over the past few weeks is that the simulation is fully flyable and usable in a predictably stable manner. This has allowed us to shift from implementation to refinement as we continue to improve the flying characteristics of the airplane and make adjustments to the autoflight system control laws in both normal and CWS modes. Since this is our first project working to bring our entirely customized capabilities into the MSFS platform and it has been interesting as we adapt the handling qualities. Each platform has it's own set of strengths and weaknesses, so we are likewise adjusting the 737 software to account for the strengths of the MSFS platform, while also working around some of the weaknesses. We went through this process when initially bringing our products from FSX to P3D, but those two platforms were alike enough that it wasn't terribly difficult in the beginning.

    This is an order of magnitude more complex than that effort from 2015, but we are really pleased with the results!

    Checking the performance of the airplane requires a tremendous amount of detail flying work to validate that the pitch/power/drag interactions are correct at all altitudes, configurations and weights. It is exacting work, but it is going mostly well.


    All over the airplane we are heavily engaged in cleanup-mode now- and we have chosen a go-to-beta date. Our confidence in hitting that beta date is very high, and we are also feeling confident enough in the project to begin setting a projected release date range on the calendar. (No, I'm not going to tell you what it is because that would be a sure-fire way create the sort of bad karma that would cause a lengthy delay! )

    I have begun work on some video segments, but I don't want to say too much about those yet.

    Overall, we are finally starting to feel good about the progress we are making with this project. The whole kit is finally beginning to look, act and feel like finished product.

    The wait is nearly over!

      sounds awesome! cant wait to see it in action!
      one question, Will the performance numbers be calculated in sim? or will it be EFB or do we need to find a calculator else where?

      secondly, will the EFB connect with the FMC? for instance like in the p3d models where you calculate performance, you can copy info from the FMS but not send it to the FMS?

      thanks again! no matter what itll be great!

        Brandon- The EFB modeled is the EFB offered by Boeing as an option for the airplane it interacts with the airplane in the same manner as the one offered by Boeing. - RSR

        Nameless- Please do add a signature to your posts- we insist upon it here. :-) With regard to Xbox- that is still planned, yes. Currently we are still waiting for a change to the Xbox side that will allow our projects to run on that platform. (DC-6 was released for Xbox but then removed as it was found that an update was needed to allow projects like ours to operate on Xbox.) The last update we had from MS was that the update is still pending and that it might be a few months. Once that happens, I fully expect 737 to be available there as well. - RSR

      Thankyou for the information and the wonderful pics Robert,this is great news and im very much looking forward to release of this beautiful looking aircraft.

        This is so awesome! It’s been over a year now since I had to move to XP11 (because nothing in MSFS works but I was too spoiled by the quality of it and couldn’t stand P3D anymore…) and I only recently start to fly a few full flights in MSFS with the CJ4. I was shocked that the sim really starts to behave on my computer, no more CTDs, stably over 25 fps at most time, and even better quality at day time in most parts of the world. I have to say I struggled too much on controlling the aircrafts before and didn’t really enjoy the platform until now. I can’t describe how excited I am for the coming 737! I see many sleepless nights and tiring mornings in my future!

            Okay, i see the aircraft is never coming to Xbox.

              In the last Q&A, Asobo Developers clarify that the problem is Xbox is a closed platform, with a lot of security locks to avoid virus and malwares. This locks dont exist in the developers xbox hardware, so they simply don't see the problem before the release. The fix isn't in hands of PMDG or even Asobo, is in the hands os the Microsoft Xbox Software Team. So all of us need to wait, because more important than the planes is a secure platform.

              Daniel Arantes.

            How exciting! I'm super happy to know I'll have my hands on this bird sooner rather than later!

              sounds good RSR... I have the feeling that the spring 2022 will be very very exciting 😉
              Chris Mbe


                Today we celebrate the independence day. That's my prediction for release date . In seriousness. I'm hoping PMDG is not going to move the release date around to match some symbolic date in history and just releases it next day after it's done and ready . Year and a half two years of wait for me for my T7 and QOS but at least now we know it's possible in a practical sense to have those two in MSFS.

                  Annoying variables exist. That's why you never speculate on release dates.

                  If I'm a developer I never speculate on release date because people will eat me alive if I miss them. Which is kind of funny because it's not like they gave me money upfront. If I'm on the other side of the curtain I can speculate about release dates because it's fun, like gambling where I don't loose any money. .

                  Aleks - well, the good news is that there is no July 37th, so there really isn't much on the calendar that would be worth waiting for. When it is done, we will release it. :-) - RSR

                Keep on the good work

                  Thank you Robert for the update and looking forward to the 737!

                      Beta is music to my ears. Hopefully it will all go smoothly and that release timeline can be stuck to.

                      I really look forward to loading up the NG3 and battling the harsh Canadian winter with flights from Yellowknife - Iqaluit and back (Canadian North).

                      Keep up the fantastic work and if it all hits the fan then we can wait for another few months...

                                          Robert's last statement on this was that it was on par with default aircraft or even a bit better.

                                        Good to read and see that its moving along. I will refrain from commenting about progress anymore in case the denizens of Karma are listening. 🤨

                                        I'll be looking forward to it, 2 weeks ago I uninstalled P3D. I realised I just wasn't using it anymore. The move from P3D to MSFS was gradual starting with the DC6 and as aircraft like the FBW 320Neo improved I found myself flying aircraft on P3D but missing the atmosphere, feel and graphics of MSFS. Yes the weather and traffic need work, and we all know that the study sims are slowly approaching, but I was getting more out of MSFS. How many thousand hours on FSX and its derivatives of P3D over the years for me? So its a large step away from something that has been on my PC constantly since it was released.

                                        So fingers crossed for a good year with PMDG and the 737, some visibility on the 747 and 777 maybe the 757 and of course the big wish of the 767 for long term.
                                        And of blue skies for the new kids on the block Fenix with the A320 Ceo and TFDi with the PMDG version of Beetlejuice, the MD-11 (type it out 3 times and Robert appears )
