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

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

    Correct engines, NGXu, best aircraft performance file.

    I’m using a 737-800 profile from Aircraftperformance.net for PFPX. What are the correct engines modeled on the NGXu, and what is the most accurate aircraft perforce file (PFPX) for the NGXu? Thanks!

    In the FMC, In the IDENT page you can see which engines each plane has.

      PFPX performance profiles from AirlinerPerformance are accurate, adjust weights and capacities accordingly.

          As far as engines are concerned, the FMC ‘Ident’ page only indicates ‘Engine Rating 26K.’ Would I be correct to assume this would be the -26 engine?

            In PFPX what are your 737-800 engine choices?

              Von, in PFPX my only available voice is the CFM56-7B26. I always us the aircraft performance files downloaded for free from http://airlinerperformance.net. Apparently these are known as the most accurate.

                David,
                I figured you had read this post:
                https://forum.pmdg.com/forum/main-fo...s-and-ngxu-fmc

                Anyway, that is the same engine choice I see in PFPX.

                  Yes I have, however there seems to be some conflicting disagreements in that thread regarding proper weights, engines, etc.

                    Right.

                    Maybe there is an updated set of PMDG templates for PFPX somewhere?

                      the CFM56-7B26 is the correct engine

                        David,

                        I had a look at the aircraft cfg:
                        performance="Cruise Speed:\nMach 0.789 (455 kts; 842 km/h) \n\nEngines:\nCFM56-7B24 \
                        The CDU says 26K , The P3D aircraft selection screen says 26K

                          The aircraft.cfg file can contain textual errors, cut and past errors. Funny how it was the place to go for the B747 data but not so much in the NGXu. For example, the EFB is the data source for weights not the aircraft.cfg, which does not have the same numbers. The -800 is 26K thrust and the -900 has the 27K "bump."

                            Dan,

                            Thanks for confirming.

                            My PFPX -800u, American AAL N921NN with CFM56-7B26 and -900u Alaska ASA N495AS with CFM56-7B27 are all ok, no changes required.


                            Edit:
                            Checked the -900 cfg:
                            [General]
                            atc_type=BOEING
                            atc_model=B739
                            editable=0
                            performance="Cruise Speed:\nMach 0.789 (455 kts; 842 km/h) \n\nEngines:\nCFM56-7B26

                              I noticed this. Possible textual error discrepancy. CFM56-7B26 it is.

                                As far as I know, these profiles https://forum.aerosoft.com/index.php...profiles-pack/ are more accurate, but in any case you need to adjust weights and capacities to match
