The chart supplement for KSNA mentions the following
AIRSPACE: CLASS C svc ctc APP CON svc 1415–0700Z‡ other times CLASS G.
I know that SVC means service. I've gathered that KSNA is class C from 1415 - 0700Z (which is 6:15am - 11pm PDT local time). My questions are the following.
- It says "svc ctc" and "APP CON svc." What does this mean? My first guess is, both control tower and approach control are in effect. Is that right?
- What is ctc? Control tower?
