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.

    737-900 vs. 737-900ER: Differences?

    Hi folks,

    I am puzzled about the differences of the 737-900 and 900ER aircraft.
    According to wiki the 900ER should fancy bigger tanks.

    The Alaska livery aircrafts claim to be verified, maybe I am be mistaken, but I think the tanks are the same.
    Is a 900ER without the additional tanks an ER?

    Other differences except the visible additional exit doors and an invisible flat rear bulkhead?

    Thanks in advance.

      I don't think United uses the extra tanks either. I mean they can easily make Hawaii from SFO at max ZFW in the 900ER...as far as I know anyway.

        The wing tanks and the center tank sizes don't change between the -900 and the -900ER. Should the customer choose, there is the option for auxiliary tanks. That said, the main difference between the two other than optional auxiliary tanks for the -900ER is the -900ER has the mid-cabin emergency exit door, which allows it to carry more than 189 passengers if the operator so chooses. In addition, it has a higher maximum zero fuel weight and a higher maximum take-off weight compared to the -900.

          Most of the time with big airplanes, range with a serviceable payload comes down not to how much fuel you can HOLD, but how much you can LIFT.
          ​​​​​​
          The changes that make the -900ER more useful than the -900 for most operators are as Kevin said the increased weights. More fuel can be pumped into the tanks for a given revenue payload, so it can be flown farther.

            Hi folks,

            a Happy New Year to you.

            Which airlines or even concrete aircraft got the extra fuel tank(s)?

            Thanks in advance.

                  I wouldn't know to be honest. But I imagine that is information you can find on the google machine. Or bing if you are a wild man.

                    The Private Air 737s had them...
                    The bigger airlines don't seem to regard them as necessary.
                    Maybe Westjet, when they used to cross the pond to Glasgow...

                      West Jet actually doesn't have any 900s. They do however use 767s for those routes. I believe they have also ordered 787s as well.

                        Turkish Airways I believe has one aux tank for their 900ERs.

                          Hi Will,

                          correct, Westjet operate -600s, -700s, -800s.
                          About two years ago they crossed the pond I think with their -700s ... short ones like CYHZ-EGPF.

                          Then 767s, now 787s.

                            That's pretty rad about the 700. I recall BA used to fly an A319 from JFK-LHR as well. I wonder if purchasing 900ERS was something WJ thought about though. Wouldn't surprise me.
