Operating constraints
Bert Mooney Airport has published operating constraints in five categories: access, runway notes, environmental, pavement strength and other notes.
Taxiway D is restricted to aircraft with a wingspan less than 100 feet without prior permission; call the airport manager.
MALSR is activated on runway 15; REIL is installed on runways 12 and 30; PAPI is installed on runways 12 and 30; VASI is installed on runway 33; MIRL serves runways 15/33 and 12/30, controlled via CTAF. The PAPI on runway 15 operates continuously.
The PAPI is unusable beyond 5 degrees right of runway centerline.
The PAPI is restricted to 2.1 nautical miles from the runway 30 threshold due to high terrain, and is unusable beyond 2 degrees right of runway centerline.
Do not use the VASI beyond 1.5 miles from the runway due to high terrain.
Deer are present in the vicinity of the airport.

Frequently asked questions
What runway length is available at KBTM?
Bert Mooney Airport (KBTM) offers a primary runway, 15/33, measuring 9,000 feet by 150 feet with an asphalt surface. A secondary runway, 12/30, spans 5,100 feet by 75 feet, also asphalt. The longer runway supports larger business jets operating into this high-elevation Montana field. Field elevation at KBTM is 5,550 feet, a factor dispatchers should weigh alongside runway length for performance planning. Both runways are paved and suitable for a range of turbine aircraft.
Does KBTM have customs available for international arrivals?
Yes, Bert Mooney Airport (KBTM) has CBP inspection services available onsite. This allows aircraft to clear customs directly at the field rather than diverting to a nearby port of entry. The airport is public use and uncontrolled, with an attendance schedule running dawn to dusk every day. Crews planning international arrivals should coordinate timing with CBP given the daylight-hours attendance pattern rather than assuming round-the-clock availability. No nearest alternate customs airport is listed, reflecting the onsite service.
What fuel types are offered at Bert Mooney Airport?
Bert Mooney Airport (KBTM) stocks 100, 100LL, and Jet A fuel. This combination supports both piston aircraft and turbine business aircraft operating through the field. The airport is attended dawn to dusk daily, which is the window during which fuel services are available. With a 9,000-foot primary runway and Jet A onsite, KBTM is equipped to handle a range of business aviation traffic through southwestern Montana.
Are there terrain-related approach restrictions at KBTM?
Yes, Bert Mooney Airport (KBTM) has several visual glide slope indicator restrictions tied to surrounding terrain. The PAPI for runway 30 is restricted to 2.1 nautical miles from the threshold and unusable beyond 2 degrees right of runway centerline, both due to high terrain. The PAPI for runway 15 is unusable beyond 5 degrees right of centerline. The VASI system should not be used beyond 1.5 miles from the runway, also because of high terrain. Crews should brief these limitations before flying visual approaches at KBTM.
Is there a cold temperature restriction at Bert Mooney Airport?
Yes, KBTM is designated a cold temperature airport requiring altitude correction at or below minus 24 degrees Celsius. This designation affects instrument approach procedures, since published altitudes may not provide adequate obstacle clearance in extreme cold without manual correction. Dispatchers and crews operating into Bert Mooney Airport during winter months should apply the appropriate cold weather altimetry corrections per procedure. The field also reports snow removal operations during periods of snowfall, relevant given the region's winter climate.
