Frequently asked questions
What runway does KMSV offer for business aviation traffic?
Sullivan County International operates a single asphalt runway, 15/33, measuring 6,298 feet long and 150 feet wide. That length accommodates most midsize and super-midsize jets without restriction under normal conditions. The airport is non-towered, so arrivals and departures are coordinated through CTAF. Runway lighting, including REIL on both ends and HIRL, is pilot-activated rather than continuously staffed. PAPI is available on both 15 and 33 and operates continuously.
Is Jet A fuel available at KMSV?
Jet A is available at Sullivan County International, but only during the 0800 to 1700 window. Operators requiring fuel outside those hours must submit advance notice to arrange service. Self-serve 100LL, by contrast, is available around the clock without prior coordination. Dispatchers planning after-hours jet operations should build fuel arrangements into the trip plan ahead of arrival. Both fuel types are confirmed as available at the field.
How does business aviation traffic at KMSV vary throughout the year?
Traffic at Sullivan County International (KMSV) shows a pronounced summer peak, with business aviation operations climbing from single digits in winter months to 176 in July and 204 in August according to FAA TFMSC data. Spring months build gradually, with May and June already showing increases over the winter baseline. Activity falls off sharply after August, dropping to 71 operations in September. Winter months, January through February, see the lowest volumes of the year, in the mid-teens. Operators should expect the busiest ramp conditions and highest demand for services during July and August.
Where is the nearest customs facility to KMSV?
The nearest customs-capable airport to Sullivan County International is New York Stewart International (KSWF), located approximately 33.18 nautical miles away. Sullivan County International itself does not have onsite customs processing. International arrivals requiring customs clearance need to route through KSWF or another customs-designated facility instead. This distance should factor into routing and scheduling decisions for any trip originating outside the United States. Dispatchers should confirm current customs procedures directly with the receiving facility before planning an international leg.
What wildlife or obstacle hazards should pilots know about at KMSV?
Pilots operating at Sullivan County International (KMSV) should be aware of birds, waterfowl, coyote, and deer reported on and in the vicinity of the airport. Separately, an 8-foot ground obstruction is noted 320 feet left of the runway aer point. These hazards are relevant to both traffic pattern planning and taxi awareness, particularly during dawn and dusk periods when wildlife activity tends to increase. Crews should maintain visual scanning during approach and departure phases given the reported wildlife presence. No towered ATC service exists to provide additional wildlife advisories at this field.
