    @B744ERF Thanks for the explanation, I’m not that familiar with the triple INS setup yet

    @B744ERF Thanks for the explanation, I’m not that familiar with the triple INS setup yet

    Triple INS has several benefits, and is required for oceanic flight:

    • Redundancy (3 units are better than two)
    • Three units are the minimum required for position mixing

    Position mixing is where the inertial positions of all three INS are mixed (NOT averaged) using a specific algorithm that weights the individual inertial positions to produce the "mixed position", that represents the aircraft position for all navigation.

    In triple mix, each INS does the following:

    • Determines its own inertial position at all times
    • Reads position data from the other two units
    • Calculates the mix position
    • Compares its data with the other units
    • If they agree, then they all use the same position mix data which is applied as a correction to their own internal inertial position
    • The triple mix position data is updated as the aircraft flies and the above functions repeat
    • If a unit diverges from the triple position too much (drift rate too high or position invalid) then the system reverts to single-unit operation but maintains the last good triple mix update (in single-unit mode, the triple mix update can be cleared from each unit by the pilot should it be inaccurate).

    Even in single-unit mode, there are continuous checks on various sub-systems, and depending on what faults are detected, generates error codes.

    Most position faults are terminal in flight and can't be corrected. The only positional error that can be fixed is a bad position update, but generally once a unit loses its position, it can only be used for attitude information.

    If a platform "topples" (literally stops remaining parallel to the local surface) then the unit is completely inoperative and must be switched off.

    Local surface refers to the Earth's surface directly underneath the aircraft/unit.

      @B744ERF Hi, I know that you don't really speculate on a release date yet, but as things currently stand would you say that a release sometime this year might be realistic or do you think it'll take longer than that? Thanks.

        @JoeNuts Should be this year, yes. Sooner rather than too much later too. Fingers crossed.

          Could you please release some vids demonstrated the sounds of cockpit and engines? Just like what you've done with Bae 146 and A300.

            @centurion88 Will try our best to sort some for you, just balancing between progressing the code and getting new In dev material out to you patience people. Thanks, just bear with us.

                  @centurion88 There is yes but it's not the fastest of progress and there's nothing we're able to show currently. We hope to be able to bring you up to speed within the next couple of weeks with some new In. dev content. Do bear with us and thanks for your patience.

                    @Voice-of-Reason No sweat, JF - while a few folk are getting a bit short on here its only because it's such a highly anticipated aircraft. We're only glad that someone has decided to develop these classics. Thanks for putting up with the attitudes!

                      @iainp93 I've been waiting long enough for a good study level 747 Classic that another year or two of waiting won't bring all too much sweat if the result is worth waiting for. I am instead taking the time in waiting to assemble my airport collection so I have a nice broad collection of Routes to fly when I can finally commission one for my fleet :)

                          While I wont necessarily fly any routes that have been handled by 747 Classics in real life, I have still planned my first routes which will cover a lot of airports around the world. And of course my first flight will start at Paine Field in Everett. :)

                            @SimeonWilbury Completely agree. As Guy Martin would say - "Do it well, do it once." The wait will be absolutely worth it.

                              In case you're not already aware of it I'd really reccommend http://departedflights.com/ for old Passenger schedules and route maps, it's pretty much my bible for most of the routes I fly. My current regular aircraft are the MaddogX MD80 and the PMDG 744 which are both mostly retired from Passenger service so I rely a lot on historical schedules when I fly in the sim.

                                Do you consider releasing an "Early Access", just like what Captainsim has done with their new 737cl? I just cant wait to see a new 747cl for p3dv4/v5 platform. Although an early access means bugs and faults, it can be fixed through the update.

                                  As i had my hopes up for this project.I lost almost all hope/interest of seeing this one released.I have a feeling that it's mostly issues with the 3rd party developer doing this project.
                                  If it ever sees the light of day in our sims,i'll be happy to use it.But for now,i'm not expecting it to release anytime soon if ever....

                                      Yep this plane is vaporware now, I do hope it will get released in the near future. Maybe this year possibly.
                                      This really sucks because I always wanted to fly a decent 747 classic especially since the days with the CLS 747-200.

                                        Yep this plane is vaporware now, I do hope it will get released in the near future. Maybe this year possibly.
                                        This really sucks because I always wanted to fly a decent 747 classic especially since the days with the CLS 747-200.

                                        Do you understand the meaning of the term 'vaporware'? I'll assume, out of goodwill, that you don't and that what you meant to write was "this plane is taking a very long time to make because it is so big and complicated.".

                                          Yes I know that Vaporware is software that has been advertised but has not yet been released either due to delays or continued development. What I was trying to say was the 747 Classic is taking much longer than we all expected. I am concerned about the project at this point and I am hoping development will continue.

                                          I did hear it was an issue with the development of the 3D model. Whatever it is I do hope it will be resolved very soon. The reason I say this is because I care about the product and I want to see it in our sims!

                                          To be honest I'm glad you chose the 747 Classic as the project, not too many 747 classics out there for P3D v4.
