Q

What is the Class C Outer Area, and how does it differ from Class C airspace?

A

The Class C Outer Area extends from the 10 NM boundary of the Class C airspace’s outer shelf to 20 NM from the primary airport, typically from 1,200 feet AGL up to 4,000 feet AGL. Unlike Class C airspace, communication with ATC is optional but encouraged, and it is not depicted on charts.
