    Question FSX - 737 - PM - Waypoints

    Hi Guys!

    I am currently using FSX and a PMDG 737-700 together with PM.
    Honestly everything is working fine with my whole setup.
    There is only one nasty little bug that it bothering me:

    When i fly LNAV/VNAV the plane is always turning into the waypoints. Always short to the waypoints, the plane turns left to get the waypoints. Seems as it wants to reach them flying over them.

    I first thought it would be a Yaw Damper issue but it wasnt.
    Is there anyone else having this problem and is there a patch available?

    And if not...can u recommend a good 737 for the FSX and a good matchng flight model for the PM CDU?

    Many thanks and all my best wishes for christmas to you all guys...

    Yes, this is a problem several of us have observed and reported. The PM folks say it is fixed in the latest updates, but i've not had a chance to check that yet. I believe it is caused by actually tracking the wrong course when leaving the previous waypoint -- you can see that if you use a 5 or 10 nm range on the ND. The course followed appears to diverge from the correct one at a constant angle until within a few miles of the target waypoint, then curve in to correct itself.

    From my experiments i believe the divergence is the difference between the Magnetic Variation in FS9 and that in FSX.

    What versions of the PM modules are you using?

    Regards

    Pete

    Don't want to hijack your thread here but can I ask if you needed to do anything special to install the PMDG 737 in FSX?
    I've got Project Magenta and Opencockpit's MCP and EFIS and I'm looking for a good model 737 to use.
    Do I just install the software the same way as FS9 or did you have to make up a dummy FS9 folder and trick the software into thinking it was installing into FS9, then copy the aircraft files over to FSX?

    Thanks

    Paul

    Thank you John,
    I never realised that I was giving you so much to describe.
    I really appreciate it I have received the email and will have a bit of a readup on it tonight.
    Got a couple of grandkids to look after for the next 2 days so will not get a chance to install it until Wednesday at the earliest.
    You explanation is very comprehensive so I should be able toget this up and running this week.
    Once again thank you

    Paul

    Hi

    I thought we had this issue more or less sorted. Can you let us know if this is happening with current builds? And if so where you are flying in the world so I can make a test re the mag var. Thank you.

    Jonathan, I have the same problem.

    My habitual flights are Spain and the routes through the Mediterranean (example LEZL LGZA)

    I use the suite of Boeing with the last update.

    I use the latest updates and i tried the PMDG and POSKY and the default 737 in FSX.
    Always the same problem.

    Hi

    I made some tests, I do not see this problem. LEMG -> EDDS. First section is with no wind / clear. Second is with 25kts almost cross. Tracking appears perfect and no map shift that I can see. Perhaps I miss the point of the problem though? Someone said 'turning in' but the a/c passes over each waypoint perfectly? Please see images, and then please offer a suggestion on how to show me specifically the error so I can recreate. Thank you.
