About Glacier Park International Airport
Overview
Glacier Park International Airport serves the Kalispell, Montana region, providing access to northwest Montana and proximity to Glacier National Park. Located at 2977 ft MSL with three asphalt runways, the airport supports regional and commercial aviation in a mountainous terrain environment. Its medium-sized infrastructure accommodates diverse aircraft operations in a challenging geographic setting.
Flying Conditions
Weather at KGPI demonstrates significant variability, with visual flight rules (VFR) conditions predominating at 74.8% of observations. Temperature ranges from -18°C to 29°C, creating potential for significant temperature-related performance considerations. Wind patterns are predominantly southerly at an average of 6.7 knots, with calm conditions occurring 48.1% of the time and maximum gusts reaching 33 knots.
Notable Features
The airport features three runways with substantial length, particularly Runway 02/20 at 9007 feet, enabling operations for larger aircraft. Situated at coordinates 48.310501, -114.255997, the airport's elevation and surrounding terrain suggest potential mountain wave and orographic effects. September through November represent the most consistently favorable VFR months for operations.
Approach Considerations
All three runways demonstrate 100% favorable wind alignments with modest average crosswind components. Runway 02/20 presents the lowest average crosswind at 3.2 knots, potentially offering the most consistent approach conditions. Pilots should anticipate reduced visibility in approximately 5.6% of observations and prepare for potential instrument meteorological conditions, particularly during winter months.
