Frequently asked questions
What is the longest runway at KSLK?
Adirondack Regional's primary runway, 05/23, is 6,573 feet long and 150 feet wide with an asphalt surface. A second runway, 09/27, measures 3,997 feet long and 100 feet wide, also asphalt. The length and width of Runway 05/23 make it the field's principal runway for business jet traffic. Runway 23 carries MALSR approach lighting that must be pilot-activated on CTAF, and Runway 05 has a PAPI that operates continuously.
Does KSLK have customs available for international arrivals?
Adirondack Regional Airport (KSLK) reports CBP inspection services available onsite, supporting international arrivals without requiring a diversion to another customs airport. This places KSLK among the northern New York fields with direct federal inspection capability rather than reliance on a nearby customs location. Operators planning international arrivals should coordinate with CBP directly given the airport's non-towered status. No nearest alternate customs airport is listed in the data, consistent with onsite service being the primary option.
Is jet fuel available at KSLK?
Yes, Adirondack Regional Airport carries both 100LL and Jet A fuel on the field. This dual fuel availability supports both piston general aviation traffic and the business jet operations that make up the bulk of the airport's annual activity. Attendance hours run 0600 to 2100 from May through October and 0600 to 2000 from November through April, which governs when fuel and field services are staffed. Operators should plan arrivals within those windows given the airport is non-towered.
Are there any wingspan restrictions on taxiways at KSLK?
Yes, Taxiway B at Adirondack Regional Airport (KSLK) is unavailable to aircraft with a wingspan of 79 feet or greater. Operators of larger business jets and any aircraft approaching that wingspan threshold need to plan ground movements around this restriction before filing to KSLK. The restriction is specific to Taxiway B and does not apply to the airport's runways. Dispatchers should confirm current taxi routing with the airport given this limitation.
Does KSLK require cold temperature altitude corrections?
Yes, Adirondack Regional Airport (KSLK) is designated a cold temperature airport, requiring altitude corrections at or below -32C. This designation reflects the field's northern location and elevation of 1,663 feet, where reported temperatures can drop well below freezing; climate data shows an average of roughly 30 days per month below 32F in December and January. Crews operating into KSLK during winter months need to apply the required cold temperature altitude corrections on approach procedures. This applies specifically at or below the -32C threshold stated for the airport.
