Hey guys can you check the Airport Data for GLRB (Monrovia).
It seems the Airport and the ILS are about 50 Meters off.
This happens in MSFS and Xplane as well so its not a scenery Issue.
Xplane WED also says the CIPF Data for the Airport is outdated.
@NAVData
You can just spawn on the runway 04 of that airport in msfs or xplane and tune the ils 110.30 CRS 042 .
The needles wont be aligned at all.
If you open Navigraph you will also be off the runway on the moving map.
Made a shot for you that should clarify the issue. In MSFS its the same.
Hi,
Thank you very much for this additional information. I have looked deeper into it now …
First, I have checked the runwa threshold coordinates in our database and indeed they are slightly off. But and thats the point here - we don´t offer runway thresholds in X-Plane nor in the MSFS. The X-Plane data doesn´t contain any runway-information (general) and in the MSFS we only add runways, when an airport is missing in the MSFS. When the airport exists in the stock data, the data contains also no runway-information.
So, in other words - both issues are also there, when you don´t use our data - because in X-Plane and in MSFS we offer any runway-data to this airport.
Back to my first observation, that the coordinates are wrong. The main point here seems to be wrong data from the AIP because it looks that all data in the sim´s are wrong. For MSFS I´m not sure because they use normally the sat images but anyway. Normally the scenery designer uses the AIP coordinates and that would explain why are all wrong.
Another option could be (for me unlikely) that they have gotten a new runway and the coordinates are correct.
I can´t really verify it because there is no access to their AIP therefore I can´t really say whats the real reason for that offset is. Sorry.
Yeah that’s basically what i thought. Must be some underlying issue in the delivered Data.
Xplane has an airport Editor (wed) which gives you the start and end point of the runway and if i put a satellite image below it its already off. If you place the runway correctly on the images it says that the Runway does not align with the CIPF data. So im guessing this data is offset.
