<<Out of interest do remote towers replicate the view from an existing tower- not always optimum of course but familiar and a clear bench mark or do they allow enhanced fields of view such as close to holding points or busy ramp areas so a remote controller can get a close up view from different sites around the airfield>>
Technically they can do both. The HungaoControl remote tower project in Budapest consists of tower views, plus other cameras to provide zoomed in views of operationally important areas, as well as integration of A-SMGCS data, allowing flight data to be displayed alongside aircraft on the screens.
