...the busiest nonconsolidated TRACON in the United States.
Chicago does more ops than D10, no? 😝
Chicago is a consolidated TRACON, covering both the KORD Class B and KMDW Class C. There are no other Class C or B airports around KDFW, so it is a non-consolidated TRACON.
I thought a consolidated TRACON was defined as a TRACON that was combined from multiple other facilities into one. Like SoCal, Norcal, Potomac, or New York.
Also DAL is a class B airport so I'm thoroughly confused by your logic.
