I generated an FSC flight plan from Seattle (KSEA) to SanFrancisco (KSFO). Using the 737 NGX the auto land function worked perfectly. A few days later, I made the same flight with the MD 11 but the ILS landing function had me a couple of hundred yards to the right of the runway (28R) rather than a straight in approach similar to the 737NGX. I tried it twice but the result was the same. I had adjusted the flight plan to indicate an aircraft change.I don't know why this happened but is there some difference in these aircraft that I hadn't taken into consideration for this to occur?I'd appreciate any opinons on this.Jack Fentress

Several airports in FSX have ILS with the localizer not entirely ligned up with the runway. I also had this a while ago while arriving in ELLX.

It's just a wild guess but the NGX has a "use FSX frequency" feature that may have assured that you have the correct frequency. The MD11 doesn't have that.Another thing could also be depending on where you got you frequency information from, the MD11 autotunes while the NGX you may have taken from a chart. That could mean that the MD11 could have switched to a wrong (bugged) ILS signal.You could check if those where the same frequencies the aircraft where following. Hope this makes sense Manfred

JackMaybe you mistakenly selected 27L in the MD-11. Rwy 28L is an offset ILS Approach. I land both the NGX and MD-11 on 28R using an ILS Approach with no problem. I am using FlightBeam KSFO V2.0 rather than the FSX default airport..Michael Cubine

Both 28 approaches at KSFO are straight in and are not offset... 28L is a Cat I, 28R is Cat III certified.Jack,Try running Flight 1's Registry Repair tool as admin and pointing it to your FSX.exe file - the MD-11 and 744 can be affected by a registry issue that screws up the magnetic variation data - that could explain this.http://www.flight1software.com/files/FS_Registry_Repair.exe

Ryan..........Thought I'd done that years ago but with new systems etc, it could have gotten lost in the shuffle. In any event, I'll rre-install it. Thanks for the suggestion.........also, Arjen, Manfred & Michael, thanks for your suggestions and comments also.Jack Fentress

Jack,You should do what I do. I don't have the MD11, but apparently like Manfred said it doesn't have the auto-tune to the frequency of the runway. So, what I do, before each flight, I open the FSX map then find the airport I'm flying to then copy all its data to Notepad then use it while on approach.

Diego.......In this particular case, I'm flying into the FlightBeam scenery of KSFO and Flight Sim Commander flight plans correctly reflect all of the current data for the airport. I'm going to try with the Level D 767 and see what happens. As I mentioned earlier, the PMDG 737NGX flew a perfect landing at this location.We'll see what happens next.Jack Fentress

Well, I did test the Level D 767 into KSFO and it was as reliable as the PMDG 737NGX approach and landing. I still don't know why the PMDG MD 11 has the shift to the right on final. But no matter. It still is a delight to fly.Jack F.Well, I did test the Level D 767 into KSFO and it was as reliable as the PMDG 737NGX approach and landing.
