About Missoula International Airport

Overview

Missoula International Airport serves western Montana as a medium-sized regional airport located at an elevation of 3206 feet MSL. Positioned in the western part of the state, the airport provides critical aviation infrastructure for Missoula and surrounding mountain communities. Its two substantial asphalt runways support diverse aviation operations in this mountainous region.

Flying Conditions

The airport experiences predominantly VFR conditions, with 73.9% of observations reporting visual flight rules. Winds are primarily westerly at an average of 6.1 knots, with calm conditions occurring 43.9% of the time. Temperature variations are significant, ranging from -14°C to 30°C, which can impact aircraft performance and operational planning. September, October, and January demonstrate the most consistent VFR conditions.

Notable Features

Situated at 3206 feet elevation in a mountainous environment, Missoula International Airport requires pilots to be attentive to terrain and altitude considerations. The airport features two runways: 07/25 at 4612 feet and 11/29 at 9501 feet, providing operational flexibility for various aircraft types. Both runways demonstrate excellent wind alignment, with 100% favorable wind conditions and minimal average crosswind (4kt and 3kt respectively).

Approach Considerations

Pilots should anticipate generally favorable wind conditions with westerly prevailing winds. The longer runway 11/29 offers extended landing capability, potentially preferred for larger aircraft or challenging weather conditions. Visibility averages 8.6 statute miles, with only 7.2% of observations reporting visibility below 3 miles and 6.1% experiencing fog conditions. Advanced weather briefing is recommended due to the region's variable mountain weather patterns.
