Gnoss Field Airport - NOT in Novato, California

Gnoss Field Airport (ID: 27507) — Novato, California

Gnoss Field Airport, officially designated with FAA identifier DVO, is a public-use general aviation airport located in Novato, Marin County, California. Sitting at an elevation of approximately 2 feet above mean sea level on the flatlands near the Petaluma River wetlands, Gnoss Field serves as a critical general aviation hub for Marin County and the broader North Bay region. The airport is owned and operated by the County of Marin and caters primarily to private pilots, flight training operations, and light aircraft enthusiasts throughout the greater San Francisco Bay Area.

Gnoss Field features a single asphalt runway, Runway 13/31, stretching 3,300 feet in length and 75 feet wide — sufficient for single-engine and light twin-engine piston aircraft operations. The airport does not have instrument approach procedures or an operational control tower, making it a non-towered field where pilots self-announce on the CTAF frequency of 122.8 MHz. Despite its modest size, Gnoss Field hosts an active community of based aircraft and sees regular touch-and-go training traffic from student pilots enrolled at flight schools based on the field.

The airport's geographic setting in the Petaluma-Novato corridor places it under the complex airspace structure of the San Francisco Bay Area. Pilots operating at Gnoss Field must coordinate with Oakland Center and be vigilant about the numerous TFRs and airspace restrictions that regularly affect Bay Area flying. The proximity to San Francisco International Airport (SFO), Oakland International Airport (OAK), and Charles M. Schulz–Sonoma County Airport (STS) means Gnoss Field pilots frequently navigate shared corridors and must file flight plans with attention to Class B airspace boundaries.

On-airport facilities at Gnoss Field include a small terminal building with pilot amenities, self-service fuel (100LL avgas), aircraft tie-downs, and limited hangar space managed by the County of Marin. The airport does not offer commercial airline service or scheduled charter operations. Flight instruction is available through local operators who have long served the Marin County pilot community. Aircraft maintenance services are available on a limited basis, and pilots are advised to contact the airport administration for current FBO services and hours of operation.

Novato's location in southern Marin County gives Gnoss Field a distinctive operational character shaped by marine layer weather patterns originating from the Pacific Ocean and San Francisco Bay. Morning fog frequently reduces visibility at the field during summer months, requiring pilots to monitor METARs and TAFs closely before departure. The airport identifier DVO feeds into aviation weather reporting systems, and real-time conditions are accessible via the automated weather observation at nearby stations. Pilots planning cross-country flights from Gnoss Field often reference conditions at Petaluma Municipal Airport (O69) and Santa Rosa's Charles M. Schulz Airport for broader area weather context.

For pilots traveling the North Bay corridor, Gnoss Field provides a convenient alternative to the busier towered facilities at Oakland and San Francisco. The airport's location off Gnoss Field Road near Highway 37 makes it accessible from central Novato and the Marin Civic Center area, though ground transportation options are limited compared to commercial airports. Pilots and passengers traveling onward toward the East Bay may connect through nearby ground transport options or utilize services from Livermore Municipal Airport and Oakland International Airport for broader connectivity.

The surrounding community of Novato, with a population of approximately 56,000, provides a supportive base for general aviation activity. Local pilots and aviation enthusiasts have historically been active in Marin County's efforts to preserve and maintain Gnoss Field as a working general aviation facility, recognizing its value for emergency medical transport, aerial firefighting support staging, and personal transportation across the region's hilly terrain where ground travel can be time-consuming.
