I have updated the AIRAC data of LDS and PMDG and notice that there are now discrepancies between FS9 data and the latest AIRAC data largely due to changes in magnetic variation. For example, Manchester (EGCC) used to have runways 24L and 24R but now has 23L and 23R.
Obviously, the new AIRAC data is starting to incorporate such changes but how does this affect integration with FS9 - which in my opinion is still going strong? In other words, if I'm flying an ILS under the "new" AIRAC data will I see conflicts with the old data within FS9? Is it possible to update FS9 itself with any new data?
