About San Luis Valley Regional Airport/Bergman Field

Overview

San Luis Valley Regional Airport serves Alamosa, Colorado, situated at a high elevation of 7,539 feet MSL. The airport provides critical transportation infrastructure for the San Luis Valley region, offering two runways that support various aircraft operations. Its medium-sized classification and substantial primary runway (8,519 ft) enable diverse aviation activities in this high-altitude environment.

Flying Conditions

Weather conditions at KALS demonstrate predominantly favorable VFR flying opportunities, with 90.4% of observations reporting visual flight rules. Winds typically originate from the south at an average of 6.5 knots, with calm conditions occurring 24.6% of the time. Temperature variations are significant, ranging from -26°C to 26°C, which pilots must carefully consider for performance calculations.

Notable Features

The airport's high elevation at 7,539 feet presents unique challenges for aircraft performance and density altitude effects. Two runways offer operational flexibility: Runway 02/20 provides a substantial 8,519-foot asphalt surface, while Runway 06/24 offers a shorter 3,200-foot green surface. Both runways demonstrate 100% favorable wind alignment, minimizing crosswind complications.

Approach Considerations

Pilots can expect consistent wind patterns from the south, with an average crosswind of approximately 4 knots across both runways. Visibility averages 9.7 statute miles, with only 1.5% of observations showing reduced visibility below 3 miles. September, October, and January represent the most consistently favorable VFR months for operations at San Luis Valley Regional Airport.
