Custom Aircraft Datarefs List

Custom datarefs/commands in SimVimX3 configurator

The “CUSTOM COM/DRF” tab in the main SimVimX configurator window opens a list of commands and datarefs unique to the currently loaded aircraft, so you can use them to assign inputs or outputs by clicking the line instead of typing in the datarefs in the text fields.

SimVimX already includes lists of custom datarefs and commands for certain popular third-party aircraft models, as well as for standard X-Plane models.
But for those models that don’t have a list yet, you can add one yourself.

How to add the custom dataref/command list for your model:

  • Create a file named “Datarefs.txt” in your aircraft’s root folder.
  • Add the custom datarefs and commands you need to this file, one per line.
  • No need to add default X-Plane parameters (“sim/…”), as they are already listed and categorized under “X-PLANE COM/DRF”.
  • No need to separate commands and datarefs; they can be listed in any order, grouped by category.
  • You can categorize the list of datarefs/commands using a separator: to do this, start the line with an asterisk (*)
  • When loading the list, the plugin will automatically detect if each line in the list is a dataref or a command, and, for datarefs, detect if they are writable or read-only. If the dataref/command name is invalid or not found, it will be highlighted in red.

Share the list of custom commands/datarefs

We encourage you to share your custom aircraft dataref/command lists; once a list for a specific model is fully ready, we can add it to the main SimVimX library (so that new users won’t have to add it manually).
