Byron Airport sits in Byron, California at 78.5 ft MSL. It has two asphalt runways. The longest is 4,500 ft on 12/30. The field is non-towered. CTAF and UNICOM are both 123.05. NORCAL approach and departure use 123.85 or 278.3.
No ILS approaches are published here. Pattern altitude is not published. Use the standard 1,000 ft AGL for light piston traffic unless the current Chart Supplement says otherwise. The on-field FBO is Byron Airport. It carries 100LL. Fuel is available 24 hours by credit card.
A few local items matter on a first visit. Runway 30 is the calm wind runway. Pilot controlled lighting is available from sunset to sunrise. REIL is on runway 30. MIRL is on both runways and is activated on CTAF. There is drone activity within a 7.8 NM diameter around the field up to 8,000 ft. Ultralight and sailplane activity also occurs on and near the airport. A 100-foot tower sits 5,100 ft from runway 23. A 200-foot tower sits 5,600 ft from runway 05. Rising terrain with windmills is west of the airport. A power plant 2.7 miles southeast can create thermal plumes. Avoid low overflight below 1,500 ft AGL in that area.
