Frequently asked questions
Does KJNX have on-field customs service?
Johnston Regional (KJNX) does not have customs onsite. The nearest customs facility is at KRDU, located approximately 28 nautical miles away. Crews requiring customs clearance need to plan for that facility rather than expecting onsite processing at Smithfield. This distance should factor into routing and scheduling decisions for any international arrival. Coordination with KRDU ahead of arrival is advisable given the lack of local customs capability.
What runway lighting is available at Johnston Regional?
Johnston Regional operates a single runway, 03/21, with a mix of lighting systems. Runway 03 has an activated MALSR approach lighting system, while Runway 21 uses REIL. Both ends are served by MIRL medium intensity runway lighting, and taxiway lights are also available, all controlled via CTAF. PAPI is installed on both Runway 03 and Runway 21 and operates continuously. This combination supports night and low-visibility operations at KJNX despite the airport being non-towered.
Are there obstacles near the runway ends at KJNX?
Yes, Johnston Regional has documented close-in obstructions on both runway ends. Near one threshold, trees 29 feet tall stand within 200 feet of the threshold, offset 425 feet left of centerline. On another approach, ground rises 6 feet within 200 feet of the threshold, offset 301 feet left of centerline, and trees 54 feet tall sit 122 feet from the threshold, offset 442 feet left. Runway 21 also has an unmarked pipeline over 65 feet high, 2000 feet from the threshold on both sides of centerline. Crews flying into KJNX should account for these obstacles during approach and departure planning.
What is the runway length and any special surface features at KJNX?
Runway 03/21 at Johnston Regional measures 5,500 feet long and 100 feet wide, with an asphalt surface. Both ends of the runway include a 150-foot stopway, which extends usable pavement for stopping distance beyond the declared runway length. This is the airport's only paved runway and the maximum paved length listed for the field. Operators calculating performance figures should note the stopway distinctly from the primary landing and takeoff distances.
Is there a noise abatement procedure at Johnston Regional?
Yes, Johnston Regional (KJNX) asks pilots to avoid overflights of a nearby housing area while in the traffic pattern. The recommended procedure is to fly wider downwind legs and longer departure legs to reduce noise exposure over the residential area. This is a voluntary courtesy procedure rather than a regulatory requirement, but compliance helps maintain community relations around the airport. Dispatchers routing traffic through KJNX should brief crews on this pattern adjustment in advance.
