Between 38 000 and 40 000 eur/pa net for acc/app/twr.
Before or after tax?
Slightly lower. If netto.
Nothing especially, nothing important says.
As a rule of tumb, Salary for qualified ATCO ( if financed via CRCO) is in the range of 3 to 5 average salaries for that particular country. Again as rot, 3 for twr 5 for ACS/APS. 4 for app/proc.
Exemptions in both direction existed, have existed and will be there...
