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.

    EFB to 744??

    Guys, I know that like me, most people use TOPCAT, and in a way it works, but sometimes there are some really annoying problems. for example, even though I fill in the temperature, runway condition, weight, etc, sometimes it calculates my GW as overwheight, meaning that I wouldn't be able to take off even in TO/GA. I've done these calculations several times and when I put on the toga, I take off before the middle of the runway, that is, in the TOPCAT it says I'm over the limit for a given runway, however, I manage to take off normally, it's long before I finish the runway .... is there any possibility that PMDG will someday include an efb in the 747-400? or put
    sometimes the calculations add up... sometimes he says I'm overwheight... even though I'm not.
    example: many times when I take off from runway 12 in Miami... he accuses me that I have exceeded the maximum weight for that runway, however, I manage to take off before the middle of the runway!

    I'm confused by what you mean when you say it calculates your gross weight as being overweight. Do you not manually enter in your aircraft gross weight? In any event, I'd like to see the EFB for the 747-400, but last thing I saw (and I can't find the post anymore) if I remember correctly is they need to figure out how they want to implement it since I seriously doubt it's something that would be done for free, given the amount of time it takes to go through all the data for every variant out there. If they do do it, it would be a while.

      Remember that takeoff calculations are not just about the takeoff roll but also about meeting engine-out climb gradient requirements and so it may be the second segment that is limiting.

      I am only going off a cursory glance at the charts but I see there appears to be a 100ft obstacle very close in on the climb out from Rwy 12; the DA for the ILS approach to Rwy 30 is higher than standard, I presume because of this obstacle, and it wouldn’t surprise me if this was the limiting factor for takeoffs from Rwy 12 either.

        TOPCAT's always doing a really good job on the Queen.

          Leandro, if I am not mistaken the EFB for the 747s is planned but no ETA yet. All the variants of this aircraft no doubt complicate and increase the workload for the team so it will be a while. My guess is by the time the 747 rolls out for MSFS we will have a better idea.

            Would be nice to have the EFB in the -400 as well and if so the “iPad” one. Only -400 operator in the world with the Class 3 EFB (same as -8) is Cargolux
