Duenna say I landed 1.6 nm from OR0S, but I did land at ORBI 15L.
That can be verified by the attached FSX Flight Analysis.
OR0S is very close to ORBI.
This reading in Duenna is well known from our RTW experience.
The reference point for ORBS in FS2004 is located at the takeoff end of Rwy 31L. The FSX reference point for ORBI is located near the main terminal.
Duenna uses it's own database of airport locations based on FS2002/2004 data to determine the distance of the aircraft to the nearest airport. It does not use a different airport position database for different versions of FS.
While you were on the runway at ORBI, you were 1.6 nm from the reference point in the middle of the runway at OR0S. You were also about 2 nm from the ORBS reference point.
If you check the posts of other folks for their Baghdad landings - almost everyone who landed on Rwy 15L has the same result showing the landing as being nearest OR0S.
This is an issue for many places in FSX because almost all airports moved at least a few hundred feet with the new round world model.
Whenever we see such an issue that is not already known - we check the position reported in the Duenna file with AFCAD or a similar utility for FS2004 or FSX, whichever version the pilot was using.
The attachment shows the spot where Duenna recorded your aircraft as stopping.
