PH-UKU, I cannot get into anything deeply on a public forum, both because it is public, and also because my fingers would be worn out through all the typing.
The best way for education would be for you to visit an ATC Unit, where you can find out what ATSA's (and ATCO's) do.
You are a pilot, so would be made most welcome (despite comments about ATSA's). Education=Understanding=All Happy
