Frequently asked questions
What is the runway length at KALS?
San Luis Valley Regional / Bergman Field, identifier KALS, has a single paved runway, 02/20, measuring 8,521 feet by 100 feet with an asphalt surface. That length supports business jet operations without a runway-length constraint for most aircraft types operating in the region. KALS sits at a field elevation of 7,540 feet, which affects density altitude and takeoff performance planning even when runway length is not limiting. Crews should factor elevation into performance calculations rather than relying on published runway distance alone. No other runway is listed for this field.
Is fuel available at KALS?
San Luis Valley Regional / Bergman Field stocks both 100LL and Jet A fuel, so piston and turbine operators can plan fuel stops here. The attendance schedule runs daily from 0800 to 1930 local, which brackets the window during which fuel service and field attendance can be expected. Outside those hours, operators should not assume support is on hand at KALS. There is no towered ATC service at this airport, so radio and fuel coordination outside published hours should be planned accordingly. Confirm timing against the attendance schedule before scheduling an early or late arrival.
Does KALS have customs clearance on site?
San Luis Valley Regional / Bergman Field does not have customs service on site. The nearest customs facility is at KCOS, located approximately 99 nautical miles away. Operators requiring a customs clearance on an international itinerary through KALS need to route through KCOS or another designated port of entry beforehand. This distance should be built into fuel and routing plans for any flight requiring border clearance near the San Luis Valley. Plan the customs leg separately from any operation into KALS itself.
What ARFF and apron restrictions apply at KALS?
At San Luis Valley Regional / Bergman Field, aircraft rescue and firefighting coverage is provided during scheduled air carrier operations. Outside those windows, ARFF coverage requires prior permission, arranged through airport operations, for 24-hour availability. The general aviation ramp at KALS is closed to air carrier aircraft, so operators flying under air carrier rules need to coordinate apron use separately. Unscheduled air carrier operations also require prior permission from airport operations before arrival. These restrictions mean air carrier flights should coordinate directly with airport operations ahead of time rather than assuming standard GA ramp access.
How is business aviation traffic distributed through the year at KALS?
San Luis Valley Regional / Bergman Field shows business aviation traffic concentrated in certain months, according to FAA TFMSC data for 2025. December recorded the highest monthly count at 169 operations, while August and February were the lowest, at 116 and 117 operations respectively. Annual business aviation operations at KALS totaled 1,605 against 4,165 total annual operations at the field. This distribution suggests operators should expect somewhat higher ramp and fuel demand in the winter months compared to mid-summer. Dispatchers scheduling flights around December volumes may want to confirm fuel and ramp availability in advance.
