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.

    Both the Fenix and the iniBuilds A310 use CFD now. Will PMDG follow?


    I've recently learned that the iniBuilds takes advantage of the CFD in the sim. That's the second airliner (with the Fenix) that we know of that use CFD in this sim. Some might think it doesn't do much for airliners but I have noticed the ground effect feels and looks much more natural and less static. I wonder if PMDG will jump on this train and get on par with other developers in this regard? So far PMDG haven't even incorporated the new ground friction variables (The Fenix makes great use of them). Why is PMDG taking their time to use these new features?

    What is CFD? All these acronyms, I can't keep up.

      Lol Daniel, I have no idea what it does or is either except that they draw the airstream around the airframe and wings and that Asobo‘s aircraft don‘t behave a dime better than before. Still veering off the runway, still feel the same lack of inertia whether you fly a 172 or a DA62. On the other hand my 737 feels like an airplane. 🤷🏻‍♂️

    +1 on the ground handling. Feels like there is no inertia at all. The NGXu handles much more realistically/believably on the ground in P3D.


      Before anything pmdg still has to figure out how to export their products using the latest sdk.

      I do hope they can improve the ground handling, its my only real gripe.

        Yeah and the flare feels too static, which would be fixed with cfd

      +1 on this. Ever since the latest Fenix update that they released, the plane has felt so amazing on the way it flies. They focused a lot on the ground effect and flare as well. It definitely feels amazing to fly that bird. I would love to see PMDG take on this as well. I feel like it can benefit from the CFD system that is in place so much. Definitely would love to see them also take advantage of the more variables that were added to the ground handling as well. The FBW and Fenix ground handling feels a lot better than before.

        I prefer the 737 over the A320/A310 any day of the week so I’m keeping my fingers crossed for much better ground handling and flare. I do notice a significant difference in that regard compared to the other simulations.


          One thing at a time gents. Like getting the wipers to actually wipe rain would be a step in the right direction. I agree, the flare and takeoff are not modeled/represented as well as other sims. I also hope PMDG will continue to improve as time goes on. If I knew any programming, I'd volunteer to help.

            So CFD is the new buzzword is it? Everyone now claims that their model is better "because of CFD" and the fan boys will happily write-off any model that doesn't use it.

            It's just a buzzword folks, chill.

              Contrary to your view many do view it as an advancement over static tables. Good thing you don’t make economic or programming decisions for PMDG

              Did anyone tell about this? They still use LUTs. Noobs...

            Ground handling is fine for me. Make sure you don't have FSRealistic making things unrealistic!

              A couple of points here. I can't find the post now, but this question came up here a while ago. PMDG stated that they are evaluating all of the features in MSFS, including CFD, and if any features provide a benefit they will include those features in their aircraft. I believe that PMDG uses an almost entirely custom flight model for their aircraft, so the CFD that is included in MSFS may not actually provide any benefit over what PMDG is already using.

              Also, CFD will have a mostly negligible effect on ground handling. As its name indicates, CFD is related to the flow of air over the aircraft's surface. This would only have a noticeable effect while on the ground immediately prior to takeoff and immediately after landing (or in extreme wind conditions). CFD will generally have no noticeable effect on how the aircraft taxis.

                I think you and sone other folks have misunderstood. When I say “ground effect“ I’m talking about the increase in lift you get when close to the ground like on flare for example. And that’s what feels pretty unrealistic as stated by quite a few real 737 pilots including flightdeck2sim. Since the CFD simulates the impact of the aircraft on the air surrounding it it improves simulation of that very effect. Logically, it’s why Fenix and iniBuilds are using it after careful evaluation.

                Mad_X, your comment says more about you and your problems/frustrations/troubled relation with PMDGs products, whatever they may be, than of the so called apologetic PMDG fans there that brings constructive facts to the conversation.

              Speaking of buzzwords, FSRealistic seems to be making the rounds on this forum.
              People seriously need to set it up correctly then see how it performs.
              Not saying you have not tried it Sean, but truly I wonder how many actually have it who are making comments about it, or have bothered to spend time turning off settings they don't want, and adjusting (toning down) others.
              And as for the ones that say 'it messed up my system', seriously check your system as no way it did!

              Meanwhile, back to the actual topic of this thread...​

                Agree. And I would also like to see snow hitting the windshield as snow and not rain. Heck we even had this back in FS9. Not very realistic as it is now. But that's probably more of a MSFS thing.

                  I agree +1 CFD would be very nice
