Hi,
no the license reason is for the charts yes, but you can add the import possibility from any addon/tool, when you want - there is no license reason. You can import any file/file-type, if you want and if it’s possible.
As an example:
You can import an excel- or word file without asking MS before, if you run into an license issue. The only thing is, you need a license to change it
And thats the same here, Simbrief offers a text file which contains information for a route. When WT or any other 3rd party devs want, they can import it without any license issues. So, it’s only a decision of WT to implement this, there is no license violation (it is still implemented but the decide to remove it).
Just to clarify the situation with the missing flight import. But what we have decide is, to start the analyse to create a mod to bring all the features back, what WT has removed (charts and now the Simbrief import).
Hope that helps
Richard
