They also quoted that the airspace was divided into sectors with one ATCO per sector to deal with ALL the RT, phones Etc. Maybe they should have spoken to someone who knows something about LACC operations. There are Two ATCOs and One ATSA per sector/Sector group. There were several other small errors as well. If a Uni is going to do research do not speak to NEMA TWR/APP ATCO about area ops unless he is current.
