To be fair to Str8in, the number of movements is all relative.
Anybody who has operational experience in ATC knows that there are airports with 100k movements that are much more complex environments than airports with 200k movements and so on...
Is it a mix of VFR/IFR integration or just an IFR sausage factory? How many runways? What class of airspace? Any airfields in close proximity that effect ops? I could go on and on and on. Each unit its own idiosyncrasies.
