1275389 Posted February 28, 2016 at 12:10 AM Posted February 28, 2016 at 12:10 AM It appears that runway centerlines are being affected by magnetic variation... this is causing them to appear slanted. Here is FLL's 10s and 28s for example: http://i.imgur.com/aazwoq2.jpg The fixes displayed are those on the ILSs, clearly a significant distance from what is shown to be the runway centerline. It's drawing them with a true heading of 264, 270 magnetic (using the latest update with the LA fix for the 28s). In the file from MyFSim.com, 270 is the heading it has listed for FLL. The runway heading it should be displaying is 276, it appears that in this case, it is actually subtracting rather than adding. Link to comment Share on other sites More sharing options...

1275389 Posted February 28, 2016 at 12:28 AM Author Posted February 28, 2016 at 12:28 AM That post deals with the LA command, I am refferring to runway centerlines...which is somewhat of a different bug. Link to comment Share on other sites More sharing options...

Ross Carlson Posted February 28, 2016 at 01:18 AM Posted February 28, 2016 at 01:18 AM Nope, these two issues are unrelated. The centerline rendering code uses the magnetic variation listed in the Airports.xml file, which has the correct value for FLL. (6.1083333333333334 degrees.) It's working fine for me at KBOS. Can you post your facility file for download? Developer: vPilot, VRC, vSTARS, vERAM, VAT-Spy Senior Controller, Boston Virtual ARTCC Link to comment Share on other sites More sharing options...
1275389 Posted February 28, 2016 at 01:39 AM Author Posted February 28, 2016 at 01:39 AM (edited) Done It seems like the variation is not as significant at some airports compared to others. Edited February 28, 2016 at 03:01 AM by Guest Link to comment Share on other sites More sharing options...

1275389 Posted February 28, 2016 at 01:44 AM Author Posted February 28, 2016 at 01:44 AM Tampa's centerlines look pretty close to what they should be, Fort Lauderdale's do not. (The variation appears to be less) Link to comment Share on other sites More sharing options...
Ross Carlson Posted February 28, 2016 at 03:08 AM Posted February 28, 2016 at 03:08 AM Josh, what command did you enter to get the centerlines to display?

Ross Carlson Posted February 28, 2016 at 03:35 AM Posted February 28, 2016 at 03:35 AM Did you edit your airports.xml file? Because the one distributed with vERAM has the runways at FLL as 9s/27s.

Is there any updated Airports.xml file with reliable mag var data? We've tended to have many runway changes in the past year or two. Link to comment Share on other sites More sharing options...
Ross Carlson Posted February 28, 2016 at 04:22 AM Posted February 28, 2016 at 04:22 AM Ugh ... it would be really helpful if you mention that you're using someone else's data when you post a bug report.

1275389 Posted February 28, 2016 at 04:43 AM Author Posted February 28, 2016 at 04:43 AM Argggg -- I didn't think the mag vars would be so drastically different. Link to comment Share on other sites More sharing options...
Ryan Geckler Posted February 28, 2016 at 07:52 PM Posted February 28, 2016 at 07:52 PM The runways at FLL changed from 9 to 10 ages ago... why was the data so old to begin with?

1275389 Posted February 28, 2016 at 08:15 PM Author Posted February 28, 2016 at 08:15 PM My temporary fix -- setting all the mag vars to 0. The runway centerlines are being calculated based on a magnetic heading rather than a true heading. I think this is more going to mess up other stuff than actual be a practical solution.

Ross Carlson Posted February 28, 2016 at 08:32 PM Posted February 28, 2016 at 08:32 PM My temporary fix -- setting all the mag vars to 0. The runway centerlines are being calculated based on a magnetic heading rather than a true heading. I think this is more going to mess up other stuff than actual be a practical solution. Yes, the centerlines are projected using magnetic heading, because the runway headings found in the Airports.xml file are magnetic, not true. If setting the magvar to zero in your custom Airports.xml file fixes the issue, then I must [Mod - Happy Thoughts]ume that the runway headings in that file are true, not magnetic as they're supposed to be. Why not just use the Airports.xml file that comes with vERAM and just change the runway numbers at the airports where there have been runway changes in your facility? I'll make it a priority to get an updated Airports.xml file generated, same with Waypoints.xml.
