Castle’s single 11,802 ft runway has procedures serving both ends, rather than concentrating instrument access on one direction. The mix of ILS, localiser and RNAV (GPS) guidance provides both ground-based and satellite-based approaches, with precision guidance included. Its runway length is the defining physical feature, giving aircraft requiring a long landing or take-off distance considerably more available pavement than a short general-aviation strip.
Merced Yosemite Regional and Modesto City-County-Harry Sham Field have the closest comparable breadth of published procedure coverage, while Turlock Municipal’s set is notably thinner. Los Banos Municipal and Oakdale also have smaller collections. The San Francisco Sectional adds the broader visual-navigation setting and surrounding aeronautical detail not conveyed by Castle’s airport diagram and terminal procedure charts.
