Hello, there!
My name is Vicente, I am part of the tech staff over at Portugal vACC.
We are currently in the process of developing a plugin of our own for EuroScope, which, among other features, needs to be able to set a flight's clearance flag. I could not manage to find any function for such purpose in the header file for EuroScope's plugin API.
I am reaching out because I see that the TopSky plugin is able to set the clearance flag of a flight upon confirmation of it's PDC clearance. It would be of immense help if you could share how the plugin is able to set this flag.
Thanks!
