ATCNorth ,
Couldn't agree with you more.
The original AMATS model and research sought to make our Class D TWR's the same as the US "VFR Tower"; the principal being that a Class D TWR shouldn't be controlling what they can't see with a pair of binoculars. Any IFR feed would be from the CTR, either radar or procedural.
The effect of this transformation was exactly what happens when you try to transfer a model using words not use and practise. Our Class D's control traffic miles away from the airport up to 8,500 [YMAY] in some cases.
Chris ,
You may not realise that you don't need to "bring back FS" to do the job you mention. NAIPS is our version of DUETS which easily enables the same thing without the former costs in staffing.
G'day
