Frequently asked questions
Is customs clearance available at KDUJ?
No, customs processing is not offered onsite at DuBois Regional Airport. The nearest customs facility is NY27, located approximately 71.78 nautical miles away. Operators planning international arrivals need to route through that facility or another staffed customs airport beforehand. Since KDUJ has no onsite customs officer, flight plans involving international legs should account for this detour. Dispatchers should confirm current customs procedures with the receiving facility ahead of arrival.
What runway does DuBois Regional Airport offer?
DuBois Regional Airport has one paved runway, 07/25, measuring 5,503 feet long and 100 feet wide with an asphalt surface. This single strip serves as the primary and only operating surface for all traffic at KDUJ. The runway length supports a range of business jet types, though single-runway operations mean crosswind conditions have no alternate runway option. Pilots should plan approaches accordingly, particularly given the airport's untowered status and reliance on CTAF for lighting activation.
Is DuBois Regional Airport towered, and how are runway lights controlled?
KDUJ is an untowered airport, meaning there is no air traffic control tower directing operations. Pilot-controlled lighting is used instead: the HIRL for runway 07/25, REIL and VASI for runway 07, MALSR for runway 25, and taxiway lights are all activated via CTAF. The PAPI for runway 25 remains on continuously, operating 24 hours a day regardless of CTAF activation. Pilots arriving after dark or in low visibility should be prepared to key the CTAF frequency to bring up the remaining lighting systems.
What is the traffic pattern altitude at DuBois Regional Airport?
The standard traffic pattern altitude at KDUJ is 983 feet AGL for typical general aviation traffic. Large turbine-powered aircraft use a higher pattern altitude of 1,483 feet AGL. This distinction matters for sequencing and situational awareness at an untowered field, where pilots self-announce and rely on standard calls to avoid conflicts. Crews operating heavier jets into DuBois Regional Airport should plan for the elevated pattern accordingly.
Are there any operational hazards or limitations pilots should know about at KDUJ?
DuBois Regional Airport reports flocks of birds on and in the vicinity of the airport, a wildlife hazard pilots should watch for during approach and departure. The PAPI on runway 25 is also unusable beyond 8 degrees right of the runway centerline, limiting its guidance range on that side. Additionally, runway and taxiway conditions are not maintained outside of normal attendance hours, which run Monday through Friday 0500-0000, Saturday 0500-1800, and Sunday 0800-0000. Surface work is ongoing airport-wide, and grass cutting occurs from April through October.
