Frequently asked questions
What runways are available at KDLN?
Dillon Airport, identifier KDLN, has two paved asphalt runways. Runway 17/35 is the primary strip at 6,501 feet long and 75 feet wide. Runway 04/22 is shorter, at 3,600 feet long and 60 feet wide. Both surfaces are asphalt, giving operators a choice depending on wind conditions. KDLN is non-towered, so runway selection and traffic sequencing rely on CTAF procedures.
Is fuel available at KDLN?
Dillon Airport carries 100LL, Jet A, and Jet A+ fuel types. The field is attended daily from 0800 to 1700 local time, every day of the week. Outside these hours, operators should plan fuel uptake accordingly since staffed service is not continuous. KDLN sits at 5,245 feet elevation, a factor worth including in performance planning for turbine aircraft. Confirm current fuel availability directly given the fixed daily attendance window.
Does KDLN have on-site customs clearance?
Dillon Airport does not have on-site customs service. The nearest customs facility is at Bert Mooney Airport, KBTM, located 42.06 nautical miles from KDLN. Operators requiring customs clearance need to route through KBTM or another designated port of entry. This distance should be factored into fuel and routing plans for any international arrival at KDLN. No customs type or on-site status is listed for Dillon itself.
What lighting is available at KDLN at night?
Dillon Airport, KDLN, uses medium intensity runway lighting, MIRL, on both runway 04/22 and runway 17/35. PAPI visual approach guidance is pilot-activated on runways 17, 22, and 35. Lighting activation is controlled through CTAF, which is standard for this non-towered field. Pilots should be aware that the PAPI on the relevant runway is reported unusable beyond 5.0 nautical miles from the runway. Plan visual approach guidance accordingly given this limited effective range.
How does traffic vary by season at Dillon Airport?
Dillon Airport, KDLN, shows a clear seasonal traffic pattern based on FAA TFMSC data for 2025. Business aviation operations peak in June at 143 operations and July at 125 operations. Winter months are markedly quieter, with February recording only 24 operations and December 36. This concentration means operators can expect higher activity and potentially busier CTAF conditions through the summer months. Total annual business aviation operations at KDLN reach 836 for the year.
