First off, let me say this is just an idea / suggestion.
Currently, IFATC is one large group of controllers. After global flight, controllers will need to disperse across the globe. I think I have come up with a solution for making this as smooth as possible.
For this example, I will be using Indianapolis Center (ZID) & CMH TRACON.
Indianapolis Center is circled in red.
A senior IFATC Officer would be put in charge of their native region. They would be in charge of all center controllers, TRACONs, and tower/ground controllers in said region (ZID for this example). Below this ARTCC supervisor would be an individual TRACON supervisor. There are many TRACONs in the ZID ARTCC area among CMH, but I will be using Columbus as the example. So, this supervisor would be in charge of all of the APP/DEP & TWR/GND controllers in the TRACON (CMH, OSU, LCK, MFD, ILN, DAY, FFO, TOL, FWA).
You might be thinking, isn’t FWA in the Chicago ARTCC (ZAU) region not Indy? Or maybe, aren’t TOL & MFD in the Cleveland ARTCC (ZOB) region? This would mean that the TRACON supervisor would have multiple people overseeing his area, right?
Well, here’s the solution to that: The TRACON supervisor’s base (CMH) which in this case is Columbus, is in the Indy Center region. Therefore, the Indy Center supervisor would over look the CMH TRACON. Chicago and Cleveland would still control the airspace above FWA, TOL, & MFD. Indy would just be in charge of the local controllers.
Hope this makes sense! Let me know what you think of this idea.
Also, I know this example was explicitly made for the US, but I’m sure it can be amended for other parts of the world.
