I work in ATC and we have several desks with around 12 to 18 screens. Not in that layout tho, but on a much larger banana form.
They are used at different support positions so not ATC radars. Mostly for monitoring but also used with keyboard and mouse.
The applications goes from technical surveillance of ops systems, to flow capacity (airspace capacity), meteo broadcast for all airports (ATIS) or ground-ground telecommunications of aeronautical data.








Aviation nerd fact #69
Planes don’t approach at idle power (not until the very last moment)
Unless you approach with a very steep angle, the kind that end with a crater on the runway. But it is frightening and rule 1 of piloting an aircraft is “when thingy gets scary, just close your eyes”
