is it allowed to use data in public website?

Hi Zammou,

Without details it is not possible to answer this question conclusively, but in principle, yes, if it's not for a commercial project.

You can find some projects that do this in this thread: opensky-network.org/forum/projects/57-pr...ing-opensky-data#433
Another example is provided by the analysis here: www.avsec-oxford.com/blog/cycon-2018-demo

Best,
Martin
