New FSUIPC7 beta version available: 7.5.6b

Beta version 7.5.6b of FSUIPC7 is now available. This version contains the changes in beta version 7.5.6a:

  • ON ANY RUNWAY simvar has been added to offset 0x0272 as a 1-byte Boolean (read-only)
  •  AMBIENT IN CLOUD simvar has been added to offset 0x0273 as a 1-byte Boolean (read-only)

together with the following addional updates:

  • correction to saving the state of the Open On Start option
  • MobiFlight preset names automatically changed if preset name already used (See * below for more details)
  • improvements in detecting to start the PMDG-specific threads to populate the PMDG-specific offsets when a PMDG aircraft is loaded
  • for MSFS2024, to determine the airfolder name, use the folder directly after SimObjects\Airplanes\ and not the folder containing the aircraft.cfg file (See ** below for more details)

This version is available here. This is the FSUIPC7.exe only, not the full installer. To use, download it and copy/move the file to your FSUIPC7 installation folder, replacing the one that is already there (or rename this one s that you can rollback if you have any issues).

*Renaming of MobiFlight preset names:

In FSUIPC7, preset names must be unique. However, this is not the case in MobiFlight, and the same preset name can be used in multiple aircraft, As preset names are unique in FSUIPC7, the second and subsequent presets with the same name were previously not loaded and therefore not available. With this change, if a preset name is already taken, then the preset will be renamed to prefix it with the string ‘<Vendor>_<Aircraft>_’, where the<Vendor> and <Aircraft> names are taken from the previous MF comment string that contains these.

Note that if you want details of all renamed and ignored presets, you can set logging for Extras and you will get detailed log messages when the preset files are loaded.

**airfolder name

This is only relevant for users who have set the ini parameter UseAirLocForProfiles to Yes, i.e. are using the air file (aircraft.cfg) folder to determine which profile to use. Previously, and in MSFS2020, this is the name of the folder that contains theaircraft.cfg file. However, in MSFS2024, this folder is usually called ‘config’ and as such is of no use. Now, in MSFS2024 only, the name of the folder under SimObjects\Airplanes\ (in the full location path of the aircraft.cfg file) will be used. If you are using UseAirLocForProfiles in MSFS2024, you will need to add the new/updated airfolder names to the profiles (and its a good idea to remove any existing entries).
