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.

    PMDG Aircraft Freeze between longitudes W25 to W90 (Approx)

    Hi All,

    I'm running FSX on Windows, using FS16 Weather and have the PMDG 737, 747-400, 777, DC6, MD11 and Jetstream.

    Recently I have had a hard fault where any flight that enters the area of Longitudes W25 through to W90, the aircraft listed about freeze in flight.. The simulation continues as normal, however A/P, FMS, Yoke, Throttle control stop working. All Avionics seem to continue to operate and display current information however since all functions of control stop, theres nothing I can do.

    Some aircraft react differently in the same situation, and sometimes do exactlty the same thing. For instance, If I start the simulation at an airport on the US east coast, the aircraft will remain in the position in loaded and I have no control or functions, this is for all aircraft. If I fly the MD11 from Europe to the US, the aircraft will make it to the W25 longitude and then all control and function freezes inclduing all engines shutting down (Nil CG or fuel issues present). The Boeings and DC6 will remain with engines running, however I loose control and functions with in the area stated. In the case of the 777, it starts a long right desending turn untill it kisses the earth.

    Please let me know if any one else has had this issue, I would like to know your thoughts. I haven't installed or changed anything recently.. so I'm fairly stuck on what the cause might be.

    Thank you,

    Ryan, PMDG requires you to sign your posts with your first and last name, which you agreed to when you created an account here. I'm assuming your forum username is it, but PMDG still requires this. You can set up a signature to avoid forgetting by following the instructions here:

    I've never heard of FS16 weather, but just for giggles, what happens when you fly the flight without using said weather engine. Also, what latitude are you at when this happens. You only gave a longitude range, which can be quite a far distance.

      Hi Kevin Yang,

      Thank you for the reminder...

      I meant AS16, The fault remains regardless of whether the program is running or not. As for the Lat Lon, the issue is present through all latitudes in the longitude range that I metnioned.

      Appriciate your giggles.

      Ryan Almeida.


        I've been to similar issue with Realturb Europe or RealVolMet.

          I guess with "the aircraft freezes" you actually mean that nothing moves anymore in the cockpit and not that you're picking up ice, is that correct?

          If so I'd recommend to open a support ticket, I do vague recall there was a known issue with possible workarounds available from my times in FSX but those are many years back. Maybe PMDG still recalls something.
