slight headwind component, just past the near west side hangars. Most locally based small plane pilots either land short to be going below flying speed before the end of the near west hangars or touchdown after the end of the near west side hangars for more consistent wind conditions during landing.

The typical Gnoss Field crosswind landing conditions on runway 31 are stronger than reported headwind on right base and, in a typical training aircraft, a slight amount of wind shear about 100 feet (30 m) before the runway 31 threshold, settling down to a steady crosswind - but then adding to a

In the mid-1960s, Marin County
Supervisor William A. Gnoss, who served the district where the airport is located, obtained funds from the FAA through his friendship with then-Congressman Donald Clausen by appearing at the FAA in Washington, D.C. Funds were used for runway and hangar development. In

A more reasonable explanation, regardless of the prevailing cross wind, is that the original runway orientation aligned squarely with Mt. Burdell, a 1500' mountain located just 1 mi. to the west. Several aircraft had collided with Mt. Burdell before the new airport was built, and the current

A plan was unveiled in 2014 to extend the length of Gnoss' runway by 1100', to 4400'. The FAA's final recommendation in 2016 called for a 300-foot extension, which would make Runway 31/13 3600 feet. Public commentary, especially from aviators, was negative. Many pilots contended that the FAA has

Gnoss Field is known to local pilots and flight instructors as an excellent airport to practice crosswind landings, especially during afternoons in the late spring and summer when the west wind picks up. The single (31/13) runway is on a similar heading as the close by

runway orientation provided an unobstructed approach and departure from both directions. It also became feasible to design an instrument approach with the current runway orientation which has significantly increased the utility of the facility.

Gnoss has two windsocks. During remodeling in 2007 the "13" windsock was removed. By immediate popular demand, the 13 end windsock was replaced by airport management as soon as a replacement was located.

Typical left traffic pattern 13 landings during high crosswinds are flown through varying rotor wind turbulence on the backside of
Burdell Mountain and a relatively constant crosswind near the ground.

Somehow (stories are numerous) Gnoss's single runway is laid out almost exactly perpendicular to the prevailing onshore west winds. One of the stories for this alignment is that financing from the

When Gnoss Field's crosswinds exceed pilot or aircraft limitations, local pilots generally land at
Petaluma Municipal / O69 (7.2 nautical miles (13.3 km), 327 magnetic heading) or
