Frequently asked questions
What runways are available at KILN?
Wilmington Air Park operates two paved concrete runways. Runway 04L/22R measures 10,701 feet long and 150 feet wide, making it the longer of the pair. Runway 04R/22L runs 9,000 feet long at the same 150-foot width. Both surfaces are concrete, giving KILN substantial length for large or heavy aircraft operations. Dispatchers should note that runway lighting and availability status differ between the two, so current status should be checked before planning.
Is Runway 04R/22L usable at KILN?
Runway 04R/22L at Wilmington Air Park is closed indefinitely according to the airport remarks. All runway lighting on 04R/22L is also out of service indefinitely. Aircraft planning to use this runway should treat it as unavailable until further notice is published. Runway 04L/22R remains the operational runway, with PAPI lights on that runway operating continuously from sunset to sunrise. Crews should plan around the single active runway when scheduling arrivals and departures at KILN.
Are there passenger-carrying restrictions on the runways at KILN?
Yes, both runways at Wilmington Air Park carry restrictions for certain passenger operations. Neither runway is available for Part 121 or Part 380 scheduled passenger operations exceeding nine passenger seats. Non-scheduled passenger-carrying operations exceeding 30 passenger seats are also excluded from both runways. Unscheduled air carrier operations larger than 30 passenger seats require a 90-day prior permission request submitted to the airport manager. These limits apply to both 04L/22R and 04R/22L at KILN.
Does Wilmington Air Park require prior permission for transient aircraft?
Yes, Wilmington Air Park requires a four-hour prior permission request for all transient aircraft. This applies both during published operating hours and after hours. The requirement covers any aircraft not based at KILN, regardless of arrival time. Flight crews and dispatchers planning a stop at Wilmington Air Park should submit this request well ahead of the intended arrival to avoid delays in ground handling or airport access.
What is the nearest customs facility for aircraft arriving at KILN?
Wilmington Air Park does not have onsite customs processing. The nearest customs facility is at KDAY, located approximately 34.66 nautical miles from KILN. Aircraft requiring customs clearance on arrival into the United States need to route through KDAY or another designated customs airport rather than clearing directly at Wilmington Air Park. This distance should factor into fuel and routing planning for international arrivals destined for KILN.
