KCNM is the ICAO code for Cavern City Air Terminal (IATA CNM), located in Carlsbad, NM.
Cavern City Air Terminal (KCNM) is a medium airport in Carlsbad, NM. Pilots and dispatchers reference it by ICAO code KCNM or IATA code CNM. It sits in North America.
Cavern City Air Terminal is a regional commercial airport that doubles as a busy private-aviation base. Operators benefit from full instrument approaches and an FBO infrastructure scaled for regular jet traffic, often without the congestion of the nearest major hub.
The longest runway measures 7,854 ft (2,394 m), a heavy-class field. Representative aircraft that operate comfortably here include the Gulfstream G550, Falcon 7X, and Bombardier Global 5500. In practice this most heavy and super-midsize jets operate here without restriction.
Cavern City Air Terminal lies at 3,295 ft elevation.
Local operations run on America/Denver. Scheduled airline service is light enough that it rarely interferes with charter movements, though planners should still expect to coordinate with the handling agent for international turnarounds.
SkyAccess currently tracks 23 departing and 35 arriving private-jet legs at KCNM across the next six months of operator inventory. 1 aircraft from 5 operators are based here or fly through regularly, so most empty-leg supply originates from a local fleet rather than out-of-town repositioning.
Regional fields like KCNM are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.
