HiWhilst flying a generated flight plan using RC4 the headings as shown on the Adventure Display for various waypoints seem not to be in synch with the position of the waypoints as displayed on the Navigation Display of a PSS Airbus. RC4 controllers are forever giving me a new course to steer to a given waypoint that would clearly turn me away from the correct path as shown on the PSS nav display. Is the Nav database of PSS totally different to that used by RC4 and if so is there away to solve the issue.Regards

Hi there,Two probable causes:1. Make sure you are using fsuipc v3.52 or later (there was a problem with wind corrections using 3.51)2. Waypoints a long way apart. We recommend a max of around 200 miles between wp's. The navaids may be in the same place in both databases but the method of calculating the course between them may be different. It's on my list of things to check when life gets a bit quieter!All the best,John

Hi JohnThanks for the reply. I was not using the latest FSUIPC but I had turned all weather off so that there was no wind problem because of the wind issue in version 3.51. The flightplan waypoints were only 45 miles apart. Maybe the Databases are just not compatible.Regards

i use the lat/long from your flight plan, .pln fileuntil you are told to resume own navigation, you have to fly what the controller tells youjd

Thanks JDAt the risk of becoming a bore. When told to resume own navigation I do that direct to next waypoint then continue via the PSS Airbus autopilot and its navigation display shows it following the right track and everything looks fine. Then RC4 chips in again telling me i am off track and fly on a given heading which according to the PSS nav display is taking me away from the destination but i do as told and so zig zag along the PSS flightplan track. Maybe it is just me or mine as nobody else is having the trouble. Thanks anyway.Regards

couple of things.what did you set your heading deviation on the general options screen?did you change the default?jd

Just to say the default is 15. Smaller values can give problems.All the best,John

Hi John/JDThanks for your suggestions. Altering the deviation setting higher than 15 certainly stopped RC4 from giving me alternative tracks to fly from those suggested by the PSS Airbus display. However it still remained that RC4 and the PSS Airbus display thought that the same waypoints lay in different directions.The flightplan was compiled using a freeware flightplanner so I deleted their plan and recompiled the route using the default FS9 planner.Now when I fly the same route I have no problem at all.It appears the Nav data used by the freeware planner is different to RC4 and of course FS9.How could I have doubted RC4. A great piece of software. Thanks.Regards Pat

keep in mind, i use the data in the .pln file for lat/long. i only use the navdata to look up frequencies, which aren't supplied in the .pln filejd

Hi JDIn that case I have no idea why the plan compiled by the freeware planner gives a problem and the plan compiled by the default FS9 planner does not. But it doesn't matter now I can resolve it. Thanks again.Regards Pat

what is the freeware planner? send me it's .plnthen send me the .pln from fs9. let me take a look at it. i suspect i know what it is, and it's fixed in the 4.01 release.jd

Hi JDDetails sent as requested to your help E-Mail address.Regards Pat

is there a way you can dump the plan you loaded into the fmc. we need to compare lat/longs from what the fmc thinks each checkpoint is, compared to the .pln that rc has loaded.jd

Hi JDIf I understand you correctly I can certainly import the plan into the Pss Airbus FMC, but how I get that information to you is not clear to me. I take it that you or your team is not using a PSS Airbus and so might import it yourselves.I am just off to a New Years Eve party now so the wife is getting a bit twitchy but I would like to continue with you as soon as I am free if that is OK.Happy New Year to you and your team.Regards Pat
