ASA classify their towers as Radar towers, Regional towers and Metro Class D towers.
Radar towers (SY ML BN EN CG PH CS AD CB) are Aerodrome control only and are fitted with Eurocat Barco screens. ADCs can separate aircraft using 3nm radar standards.
Regional towers, regardless of radar coverage, are class D Aerodrome and Procedural Approach towers with a tower situational awareness display
Metro D towers are Class D aerodrome control only towers at the GA fields with high intensity parallel runway circuit operations.
In my opinion, based on the current award, regional towers have the best work life balance. They don't do dogos, their rosters often rotate better, and they get paid the exact same money as everyone else working their ass off in the big smoke.
