To duplicate the FSX “Tower”, it takes a lot more than just placing the View Point in the Tower. (Thats the easy part, and need not be that accurate either).
It also requires reproducing the TOWER Gauges, including the radar gauge , and the com control panel , as well as the MP aircraft list etc etc… A whole slew of XML gauges missing from 2020/2024.
Below is an old video of a FSX controller, using the TOWER ATC Mode to control aircraft in FSX.
the “Standard” FSX ATC mode in this Video is enhanced by an ADDON that FS-Mp had to manage all those wanting to act as ATC (using the FSX Tower ATC Mode), when in a FS-MP Multiplayer session in FSX.
Many found it great fun to act as ATC is a MP session, as opposed to always being the Pilot.
