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.

    Alternates for NFFN

    I'm flying from NZAA to NFFN and the only alternates simbrief spits out for a 747 is NZAA. Is there a closer alternate that is commonly used for flights bound for NFFN with a runway long enough for a 747?

    NSTU (Pago Pago, Samoa) or NWWW (La Tontouta, New Caledonia) spring to mind as having the required runway available. Pago Pago would almost certainly be fine, but I'm not sure about NWWW's taxiway and/or parking stands as regards the 747, you'd need to look into it.

    In terms of real world operations, choosing the preferable alternate will also include logistical considerations such as having a company presence at the location, as well as having suitable infrastructure available to handle the large unscheduled influx of passengers (handling agents, accommodation, etc.) The Pacific is big, and the number of genuinely suitable airports for a diversion are relatively sparse.

    In terms of NZAA-NFFN having NZAA as the alternate, I can see the logic in it. It's only a 3 hour flight back. Plus, in a four-engine aircraft, you're not looking for something close by, so much as you're looking for something that has more than an unmanned tin shed (figuratively speaking) when you arrive with 400+ passengers needing a place to stay, and an onwards flight the following day.

      NSTU for several reasons, first being that I have the Orbx airport and it's beautiful. I've also modified the AF file to increase the parking size for spot B1 to accommodate a B748. One has to enter the ramp from rwy 8 using a GSX marshaller to spot you. There are no jetways to worry about and on departure you are just going to swing the nose forward to the hard left because there's no pushback space. I also added a RAMP GA spot for my BBJ when I want to visit for holidays. Finally, for US flag carriers Pago Pago is much friendlier and less costly because it's a US territory.

    In the military we used "island reserves" which was an additional 2 hours of fuel.

    Look in ICAO Annex 6, Part 1, on page 4-12 for more detail. You will find it on "4) where the aerodrome of intended landing is an isolated aerodrome:"

      Quick question because my English isn't that great, "for a turbine-engined aeroplane, the amount of fuel required to fly for two hours at normal cruise
      consumption above the destination aerodrome, including final reserve fuel."

      Does this mean that if my final reserve is 30 minutes, I'd have to load up another hour and half's worth of fuel? Or does this mean that it's those two hours PLUS the 30 minutes of final reserves for a sum of two hours and 30 minutes of reserve fuel?

      For me it would be 10 percent plus 30 min. hold plus two hours.

    Agree. NFFN is approved as a destination airport for civilian as well without an available alternate airport for 747, 777 and 787 based on OpsSpec C67.

      Paga Pago is about 730nm from NFFN. I'd be looking at Tonga, NFTF, as my alternative. It's closer at 513nm and has a runway length of 9170'

        The pavement strength at NFTF isn't sufficient for a 747 in RL, but lengthwise in the sim it would be fine.

          NWWW has had numerous QF 747s stop along the way, so it should be be fine. I have made a list of pacific alternates that are suitable for the 747 - minus checking for pavement strength. Some don’t have cat D instrument approaches which could make them unsuitable. I’ll have a look when I’m back at the computer.

            Thank you all for your detailed responses and additional factors that ought to be considered such as company presence and pavement strength.

              Noumea has had an A380 diversion in the past, so the pavement strength shouldn't be an issue for a 747-400. The parking stands are fine for 747-400s too; there have been many QF diversions due to fog or other such issues in the Eastern Australian cities.
