Procedure coverage

San Nicolas Island NOLF has two instrument approach sheets, but only one approach type: RNAV (GPS). Coverage reaches just one end of the single 12/30 runway, leaving the reciprocal end without a published approach. The 10,002 ft runway provides a long available strip, although the procedure set remains notably compact.

Nearby chart coverage

San Clemente Island NALF has a comparably sized chart set, while Catalina’s is slightly thinner. Point Mugu NAS and Oxnard have much broader procedure collections than KNSI. The Los Angeles Sectional adds the wider visual-navigation context that the airport diagram and instrument procedures do not provide.
