Outer Area

Nonregulatory airspace surrounding designated Class C airspace airports wherein Air Traffic Control (ATC) provides radar vectoring and sequencing on a full-time basis for all Instrument Flight Rules (IFR) and participating Visual Flight Rules (VFR) aircraft. The service provided in the outer area is called Class C service which includes: IFR/IFR-standard Instrument Flight Rules separation; IFR/VFR-traffic advisories and conflict resolution; and VFR/VFR-traffic advisories and, as appropriate, safety alerts. The normal radius will be 20 nautical miles with some variations based on site-specific requirements. The outer area extends outward from the primary Class C airspace airport and extends from the lower limits of radar/ radio coverage up to the ceiling of the approach control's delegated airspace excluding the Class C charted area and other airspace as appropriate. (FAA4)
