Frequently asked questions
What is the primary runway length at KMSO?
KMSO, Missoula Montana Airport, has a primary paved runway, 12/30, measuring 9,501 feet long and 150 feet wide with an asphalt surface. This length supports a wide range of business jet and commercial aircraft operations without payload restrictions tied to runway distance. A second paved runway, 08/26, is listed at 4,612 feet by 75 feet but is permanently closed. Dispatchers planning into KMSO should therefore plan exclusively around runway 12/30 for all fixed-wing arrivals and departures.
Is runway 08/26 available at Missoula Montana Airport?
No, runway 08/26 at Missoula Montana Airport is permanently closed according to airport remarks. Prior to closure it measured 4,612 feet long and 75 feet wide with an asphalt surface. All current traffic at KMSO uses runway 12/30, the 9,501-foot primary runway. Flight planning and taxi routing should not reference 08/26 as an active surface.
Does KMSO have a landing fee?
Yes, Missoula Montana Airport charges a landing fee for all commercial aircraft and for any aircraft over 9,000 pounds. Aircraft below that weight threshold operating under non-commercial use are not subject to this fee based on the airport remarks. Operators should factor this into trip cost planning for KMSO, particularly for larger business jets that commonly exceed the 9,000-pound threshold. This applies regardless of whether the visit is a fuel stop or a full-service ground handling arrangement.
What is the cold temperature restriction at KMSO?
Missoula Montana Airport is designated a cold temperature airport, requiring altitude corrections at or below -11 degrees Celsius. This designation reflects the risk of altimeter error in extreme cold, where indicated altitudes can read higher than true altitude. Pilots and dispatchers operating into KMSO during winter months should apply appropriate cold temperature corrections on approach procedures when temperatures reach or fall below this threshold. Missoula's winter climate data, with nearly 30 days per month below freezing in December and January, makes this a recurring seasonal consideration.
Are there any taxiway weight restrictions at KMSO?
Yes, taxiway G between the runway 08 end and runway 12/30 at Missoula Montana Airport is restricted to aircraft under 12,500 pounds. Operators of larger business or commercial aircraft need alternate taxi routing to reach runway 12/30. This restriction is separate from the airport's landing fee threshold of 9,000 pounds, so heavier aircraft face both a fee and a taxi routing consideration at KMSO. Dispatchers should coordinate ground routing in advance for aircraft exceeding the taxiway limit.
