Frequently asked questions
What runways are available at KCPR?
Casper / Natrona County International, identified as KCPR, operates two paved asphalt runways. Runway 03/21 is the longer of the two at 10,165 feet, with a width of 150 feet. Runway 08/26 measures 8,679 feet long and is also 150 feet wide. Both runways carry high pavement classification numbers, supporting a wide range of turbine aircraft. The airport is towered, with air traffic control managing runway operations during scheduled hours.
Does KCPR have customs clearance available?
Casper / Natrona County International offers CBP inspection services onsite, along with a USDA compliance agreement. This allows international arrivals to clear customs and agricultural inspection directly at the airport rather than diverting to another facility. Crews planning international flights should coordinate arrival details in advance given the compliance agreement structure. The onsite presence of both CBP and USDA services distinguishes KCPR from smaller regional fields that require routing through a separate customs airport.
What fuel is available at Casper / Natrona County International?
Casper / Natrona County International stocks both 100LL and Jet A fuel. The airport maintains an all-hours attendance schedule, meaning fuel service is not restricted to limited daytime windows. This makes KCPR a viable stop for both piston and turbine operators regardless of arrival time. Jet A availability supports the airport's business aviation traffic, which accounts for a substantial share of its annual operations.
Is there a weight restriction on runways at KCPR?
Yes, Casper / Natrona County International restricts runway use for foreign air carrier, transport category, and large aircraft categories above 250,000 pounds, except with prior permission for a limited four-hour window. Operators planning heavy aircraft movements above this threshold need to request that authorization ahead of arrival. This restriction applies across the runway system rather than to a single runway. Dispatchers handling large turbine aircraft at KCPR should factor this weight limit into flight planning and request PPR accordingly.
When is business aviation traffic busiest at Casper / Natrona County International?
Business aviation traffic at Casper / Natrona County International, per FAA TFMSC data for 2025, concentrates in the summer and early fall months. July recorded the highest count at 682 operations, followed by October at 667 and June at 643. Winter months show comparatively lower volumes, with March at 527 and January at 530. This pattern reflects a seasonal skew toward the warmer half of the year at KCPR. Dispatchers should anticipate higher ramp and airspace activity during the July through October window.
