About Aspen-Pitkin County Airport (Sardy Field)

Overview

Aspen-Pitkin County Airport serves the high-elevation mountain community of Aspen, Colorado, located at 7,820 feet mean sea level. As a critical transportation link in a challenging alpine environment, the airport supports regional air travel with its 8,006-foot runway capable of handling medium-sized aircraft.

Flying Conditions

Weather conditions at Aspen demonstrate significant variability, with Visual Flight Rules (VFR) predominating 82.7% of the time. Temperature ranges from -21°C to 26°C, with an average of 3°C, creating potentially dynamic atmospheric conditions. Pilots can expect most favorable visual conditions during autumn months (September through November), with consistent visibility averaging 9.4 statute miles.

Notable Features

The airport's high elevation and mountain terrain present unique challenges for pilots, requiring careful performance calculations and heightened situational awareness. Prevailing winds from the south (180°) average 6.1 knots, with occasional gusts up to 23 knots, and calm conditions occurring 19% of the time. The single runway (15/33) experiences favorable wind alignment 100% of the time, with an average crosswind component of just 3 knots.

Approach Considerations

Runway 15/33 offers consistent wind conditions, making it generally predictable for approach and departure. Given the airport's alpine location, pilots should anticipate potential rapid weather changes and be prepared for reduced performance due to high-altitude density altitude effects. Thorough preflight planning and awareness of local terrain are critical for safe operations at this mountain airport.
