About Gunnison Crested Butte Regional Airport

Overview

Gunnison Crested Butte Regional Airport serves the mountainous region of western Colorado, situated at a high elevation of 7,680 feet MSL. The airport provides critical transportation access to the Gunnison Valley, supporting regional aviation needs with two runways capable of accommodating various aircraft types. Its strategic location serves both commercial and general aviation traffic in a challenging alpine environment.

Flying Conditions

Weather at KGUC demonstrates significant variability, with VFR conditions predominating 85.6% of the time. Temperature ranges from -21°C to 26°C, creating potential for rapidly changing meteorological conditions. Wind patterns are predominantly northerly at an average of 6.1 knots, with calm conditions occurring 48.5% of the time. Pilots should note that September, October, and November represent the most consistently favorable VFR months.

Notable Features

The airport features two runways with substantial length: Runway 06/24 at 9,400 feet of asphalt surface, and a secondary Runway 17/35 measuring 3,000 feet on gravel. Its high elevation demands careful performance calculations for aircraft operations. Both runways demonstrate 100% favorable wind alignment, with minimal average crosswind components of 3.2 and 4.2 knots respectively.

Approach Considerations

Visibility averages 9.6 statute miles, with only 1.6% of observations showing conditions below 3 statute miles. Minimal fog occurrence (0.8%) supports generally reliable visual approaches. Pilots should be prepared for mountainous terrain and potential rapid weather changes typical of high-altitude Colorado airports. Standard mountain flying techniques and thorough preflight planning are recommended.
