Pre-takeoff checklist
I often talk to my uncle who was a pilot in the air force and worked his later years at NY TRACON. He seems to be unfamiliar with the letter designated airspaces and refers to JFK airspace, for example, as the TRSA (IIRC). I assume this was in place up until 2001, when he retired. I'd guess it was at the time of 9/11, but I was under the impression that TRSA was much older than that.
