Its dual runway configuration supports diverse operational requirements for both local and transient aircraft.

Flying Conditions

Statistical data indicates favorable flying conditions, with 73.8% of observations reporting VFR conditions. Seasonal temperature variations are significant, ranging from -18°C to 34°C, with an average temperature of 7.6°C. Wind patterns predominantly originate from the south at an average of 8 knots, with calm conditions occurring 26.5% of the time and maximum gusts reaching 30 knots.

Notable Features

The airport features two runways: Runway 13/31 at 4,797 feet with a pavement surface, and Runway 17/35 at 8,059 feet with a concrete surface. Both runways demonstrate excellent wind alignment, with 100% favorable wind conditions and minimal average crosswind (4.4kt and 3.9kt respectively). Visibility averages 8.5 statute miles, with occasional reduced conditions including fog events affecting 16.4% of observations.

Approach Considerations

Pilots should anticipate the most consistent VFR conditions during September, October, and January. With both runways demonstrating full wind compatibility, selection can be made based on aircraft performance and current wind vector. Visibility restrictions occur in 5.2% of observations with conditions below 3 statute miles, suggesting potential need for instrument procedures during certain meteorological conditions.
