Frequently asked questions
Is there customs service at KGNB?
KGNB does not have on-site customs. The nearest customs facility is Rocky Mountain Metropolitan Airport (KBJC), located approximately 38 nautical miles away. Operators arriving from outside the United States should plan to clear customs at KBJC or another designated port of entry before or after using Granby-Grand County Airport.
What terrain considerations apply to operations at KGNB?
Granby-Grand County Airport (KGNB) has terrain rising near both runway ends. Runway 27 has terrain 525 feet above threshold elevation located 6,000 feet from the threshold, plus a powerline 965 feet from the threshold. Runway 09 has terrain 563 feet above threshold elevation over 21,000 feet from the threshold. High ground also rises quickly to the east of the field, which is why takeoffs to the east are recommended only for experienced pilots.
What fuel is available at KGNB?
Granby-Grand County Airport (KGNB) offers both 100LL and Jet A fuel on a self-service basis, available 24 hours. The airport is unattended, so pilots handle fueling themselves rather than relying on line service staff. This makes advance familiarity with the self-service equipment useful for operators unfamiliar with the field.
Does KGNB require any special cold-weather procedures?
Yes, Granby-Grand County Airport (KGNB) is designated a cold temperature airport requiring altitude correction at or below -24°C. Pilots flying published instrument procedures at this field need to apply cold temperature altitude corrections when temperatures drop to or below that threshold, consistent with the airport's high elevation of 8,207 feet in the Colorado Rockies.
