I believe the problem is not with the pilots but the ATC system itself. A possible solution would be to bridge the gap between anyone going on to TS1 and controlling and Expert IFATC. A “TSATC” for example would not allow controlling on Expert but instead all privileges non IFATC currently have with the addition of ghosting. To make sure this responsibility is not abused, a theoretical and practical exam would still be required, only to a lesser standard of that of IFATC. And with a TSATC, to become IFATC you would require x number if hours and additional knowledge in a second theoretical exam, no longer allowing people to go from nothing to IFATC, These “TSATC” hours would be a requirement. Thus there would be a grading system for ATC.
This is just my solution to a growing problem, what do you guys think?
