Frequently asked questions
What runway does KDUB have and how long is it?

This is also the airport's longest paved surface, matching the field's max paved runway length figure. There is no crosswind runway option at this field, so pilots should plan around prevailing wind and terrain conditions on this single strip.
Is fuel available at Dubois Municipal Airport?
Dubois Municipal (KDUB) offers both 100LL and Jet A fuel, available 24 hours via self-serve credit card according to airport remarks. The field itself is unattended, so there is no staffed fuel desk; transactions are handled entirely through the self-serve card system. Pilots should confirm card reader functionality before planning a fuel stop, since no attendant is present to assist.
How do I handle customs clearance near KDUB?
Dubois Municipal (KDUB) is not a customs port of entry, and no onsite customs service exists at this field. The nearest customs airport is KCPR, located approximately 146 nautical miles away. Flights requiring customs clearance should plan to route through KCPR rather than KDUB, and dispatchers should confirm clearance procedures with that facility directly ahead of arrival.
What should pilots know about the traffic pattern at KDUB?
At Dubois Municipal (KDUB), all traffic patterns are flown to the north of the runway because of mountainous terrain to the south, per airport remarks. Lighting includes pilot-activated REIL on runway 29, PAPI on both runway 11 and 29, and MIRL on runway 11/29, all controlled via CTAF. Clearance delivery for departures is handled through Salt Lake ARTCC rather than an onsite tower, since KDUB is non-towered.
