Hi everyone, I’m currently running a full-scale simulator setup using ProSim 1.54 with Prepar3D v4.5. After installing the latest AIRAC update, I’ve run into an issue where many airports are no longer showing up in the MCDU. The update appears to have been installed correctly, but despite that, several airports simply don’t appear when trying to input them. Has anyone experienced something similar or knows what might be causing this? I’d really appreciate any help or suggestions. Thanks in advance! ---

I am having the very same problem using P3D v5 and ProSim A320 v 1.53 ---

Hi, Sorry, I overlooked this report … Version 1.54 seems to be outdated; I can´t test it with this version - I´m using 1.74.1 … But are you able to give me a few examples that I can check on my version here, please? I´m curious: why don´t you update to the latest ProSim version? Why do you keep on this version? Cheers, Richard ---

Having problems with AIRAC 26/03. Installed into my home sim which uses P3d v5 and ProSim A320 v1.53 After loading AIRAC 26/03 a lot of my airports have disappeared ! I understand that there is a revision 3 for the latest update, but my Navigraph programme only downloads revision 1? DaveH ---

Because my sim setup along with other soft/hard wear is set to work with my present version, at the moment unable to move versions. AIRAC updates have worked fine until now, so what’s changed? ---

Ok, understood - I can´t test it in this vesion but I will test it in the current version that I have installed here, but as I requested before: Please give me a few examples of airports that are missing. Thank you, Richard ---

All the UK airports appear to be ok, the the first one I noticed that was missing ( it was even missing from the “airports.xml” file too), was Fly Tampa [EHAM](https://navigraph.com/airport/EHAM/Amsterdam-Schiphol) Dave ---

All the Uk airports seam to be ok (UK2000), but the first one I noted was missing (including it was missing from the “airports.xml file too! Was Fly Tampa [EHAM](https://navigraph.com/airport/EHAM/Amsterdam-Schiphol) When running the “build database” in ProSim it took an extraordinary long to to perform the process and loaded a lot of .bglbckup files, which I have never seen it do that before?

Hi Dave, I don´t know about the `airports.xml` file - not a file from us (also the \*.bglbckup files), but one question - when you use the stock [EHAM](https://navigraph.com/airport/EHAM/Amsterdam-Schiphol) (so, without the 3rd party scenery), you also can´t select this airport ident? I ask, because I can´t reproduce it - I can select [EHAM](https://navigraph.com/airport/EHAM/Amsterdam-Schiphol) without any issue in P3Dv5 without any 3rd party scenery (I don´t have one). Cheers, Richard ---
