About Great Falls International Airport
Overview
Great Falls International Airport serves central Montana as a medium-sized airport located at 3680 feet mean sea level near the city of Great Falls. The airport supports regional and commercial aviation with three asphalt runways, offering substantial landing options for various aircraft types. Its geographic position in north-central Montana provides critical transportation infrastructure for the region.
Flying Conditions
Weather observations indicate predominantly favorable flying conditions, with 85.5% of recorded periods under Visual Flight Rules (VFR). Southwest winds averaging 11.6 knots are typical, with temperatures ranging from -24°C to 31°C. Pilots can expect the most consistent VFR conditions during September, January, and October, with minimal instrument meteorological conditions reported.
Notable Features
The airport's elevation of 3680 feet MSL and substantial runway lengths (primary runway 03/21 at 10,502 feet) accommodate a wide range of aircraft operations. Wind patterns demonstrate consistent favorable runway alignment, with all three runways showing 100% wind compatibility. Crosswind components remain relatively moderate, ranging from 4.6 to 8.5 knots across different runway headings.
Approach Considerations
Runway 03/21 offers the longest and most versatile landing surface, with the most stable wind conditions. Pilots should anticipate southwest prevailing winds and be prepared for potential temperature-related performance considerations given the airport's elevation. The multiple runway configurations provide flexibility for approaches under various wind conditions, with minimal directional restrictions.
