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.

    mmm, you just press the escape button, the simulator is then paused (assuming a PC), the "active pause" is only meant for short durations like taking "action" screenshots, for all other situations of longer duration the escape button IS the pause.

    Yes Trevor. I use KG in both cases.

    It could well be a problem of fuel : I use to fill in with the Simbrief datas + a10% reserve. but I am still long to prépare my flights and I was obliged to make a pause.
    I will try again, take a photo of the overhead if the problem occurs again and come back to you.

    There is no “pause” really in MSFS. It just hold position of the aircraft, everything else just goes on. So also fuel burn. You might have run out of fuel just because you “paused” the flight.

    This might sound silly - but are you using the same units on SimBrief as you are on the FMC? Do you use Kgs on one and lbs on the other?

    Francis, did you notice if one or both of your engines had failed, or if you simply ran out of fuel? The engines will run down if you run out of fuel and being single crew you might not see it happening at first; especially if you have the autopilot engaged.

    Unfortunately running out of fuel will also happen if you simply pause MSFS for a long time because It is a ‘dumb simulator’. The Pause function does not stop the PMDG B737 engines from running and so they will continue to use up all of the fuel you have on board, even though the simulation looks as if it is paused. This ‘dumb simulator’ behaviour is apparently caused by an MSFS pause issue and not a PMDG one.

    The PMDG B737 fuel feed behaves realistically in real time and so the consequences of running out of fuel will obviously lead to one (or both) engines failing and this will lead to the loss of the associated engine driven generator. If you don’t notice the engine running down you will end up experiencing a loss of airspeed and a Buffet warning. The remaining thrust from the operating engine, if any, won’t be sufficient to maintain the aircraft’s speed and/or altitude; especially if you do nothing about it.

    To sum it all up, pilot error. It's study level. Most folks would fail a calculus test if they don't crack a book.

    With so little information available there's hardly any conclusion we can draw so here's some speculation:

    "Master Caution, GEN OFF BUS, noise":
    Probably an engine driven generator was either swtiched off by you or had failed (service based failures enabled?). Of course a generator failure may lead to other failures, causing other warning lights.
    The generator tripping off disconnected the autopilot which caused the autopilot disconnect warning sound, which you may have interpreted as "awful noise".

    "The FMC showed BUFFET" Please always mention the full warnings, cautions, messages you get. It's BUFFET ALERT.
    That message, among many others, tells you that you're getting too slow and are approaching the stall.
    This could point to the "awful sound" you heared also being the stick shaker.

    "The plane lost altitude"
    Since you didn't seem to have taken control of the flightpath you probably stalled.

    So my best guess from the available information is that either you turned off a generator yourself or a generator failure happened.
    Either case will mean that the autopilot disconnected and you failed to take manual control of the aircraft, allowing it to loose speed and stall.

    In other words: A small problem, led into a loss of control inflight accident by pilot error (inaction/omission to correct the undesired aircraft state early).

    Things may of course have been totally different but without any additional information, screenshots, etc. it's impossible to determine.

Later on, the FMC mentionned BUFFET.
    I precise that the flight started after loading RUNWAY at PMDG set up and that the mention ACTIVE NONE appears in grey on the Failure screen of the FMC.
    Please, help me. many thanks.

    You have to be much more specific with the alert or fault messages that the aircraft is presenting you. There's no such thing as a low pressure generator bus, maybe it was a disconnected bus? It matters otherwise we are just making guesses.
