Frequently asked questions
How long is the runway at 24CL?

The runway is also listed as the airport's maximum paved surface length in FAA data. No parallel or crosswind runway is listed for the field.
Is there air traffic control at Boswell Airport?
Boswell Airport (24CL) is non-towered and unattended, meaning there is no on-field air traffic control or staffed operations desk. Pilots operating IFR should contact Oakland ARTCC for clearance delivery, as noted in the airport's remarks. The field sits at 205 feet elevation near Corcoran, California. Traffic advisories and self-announce procedures apply as at any uncontrolled field.
Where is the nearest customs clearance to 24CL?
Boswell Airport does not have on-site customs service. The nearest customs facility is Fresno Yosemite International (KFAT), located approximately 42 nautical miles from the airport. Operators requiring customs clearance should plan to route through KFAT rather than expect service at Boswell itself. This distance should be factored into fuel and routing planning for international arrivals.
How does the pilot-controlled lighting work at 24CL?
Boswell Airport's runway lighting is activated through a non-standard pilot-controlled lighting system on frequency 122.85. The system covers the MALSR on runway 32, VASI on both runways 14 and 32, and high-intensity runway lights. Pilots key the microphone five times to actuate the lights, three times to dim them, and seven times to turn them off. This click sequence differs from standard PCL setups, so crews should confirm the procedure before arrival.
