Procedure coverage

San Carlos has a single 2,621 ft runway, and both published RNAV (GPS) approaches serve only one end. Instrument arrival coverage is therefore directional rather than matched between Runways 12 and 30. With no second runway, that 2,621 ft strip is the airport’s only available runway length and alignment for planning.

Chart context

Nearby procedure coverage varies sharply. San Francisco International has by far the broadest chart set, while Moffett Federal Airfield and Hayward Executive also have more extensive coverage than San Carlos. Palo Alto is comparable in scale, and Half Moon Bay has a thinner set. The San Francisco Sectional and Terminal Area Chart add wider visual context beyond the procedure-specific charts, while the airport diagram supplies the field layout.
