In FSX the runway headings and also the ILS Heading of SBGR is 73/253 in the charts and also the Navigraph AIRAC Packages the headings are 95/275. so if i land with the PMDGs and other airplanes with fmc and navigraph airacs, i do land with a wrong heading... sorry for bad english...

73/253 are TRUE courses for Rwy/ILS (both 09/27 runways). With current magnetic variation at SBGR (W22), magnetic courses on approach are 095/275. Do not confuse true and magnetic courses

yes, thats right. but PMDG 744 ils displays for ils27L IDC(111.10)/253 and in FMC 111.10/275 and the landing is very strange like offset ils

It is clearly a problem in the way you set your instrumental approach data on PMDG FMC. As far as I remember, there are options on PMDG FMC panels so as to display magnetic courses instead of true courses. Anyway, after performing tests with several default FS aircrafts (those without any FMC), all SBGR ILSs are aligned on rwy axes on 095/275 magnetic courses.

PMDG 737ngx align correctly on rwy heading. only the 747-400X (Queen of Skys) my Version V2.1, aligns not correct on rwy heading. I land in AutoLandMode eg.2 deg off of the threshold... It don't matter, if i select true heading or magnetic heading in the panel. Screenshots: |

Ok. If some PMDG aircrafts as well as all default basic aircrafts align correctly in APP mode, while the 747 doesn't, it seems to be a problem with the way 747 FMC manages things and not with the ILS instrumental data. Here I'm not qualified to solve it (not having the PMDG 747). May be some other users may be able to test it more effectively otherwise you'll have to ask on the PMDG forum. The only thing I can say is that the instrumental ILS characteristics (antenna positions and ILS course relative to runway are OK). The only improvement I can see is that ILS magnetic variation should be set to W22 instead of W20 but it will only affect magnetic course DISPLAY on the map view NOT alignment on ILS.

how can i set the MAGVAR to W22? Use Airport Inspector and Editor (AIE) www.aero.sors.fr/navaids.htmlNext open your airport(APX.bgl) container and select tab: airport editor and then: airport magvar editor. |
