About Miley Memorial Field
Overview
Miley Memorial Field serves Big Piney, Wyoming as a medium-sized airport situated at a high elevation of 6,990 feet MSL. The airport provides critical aviation infrastructure in a remote mountain region, supporting local transportation needs with two runways accommodating different aircraft types and operational requirements.
Flying Conditions
Pilots can expect predominantly VFR conditions, with 88.8% of observations showing favorable visual flight rules. The airport experiences significant temperature variation, ranging from -19°C to 26°C, with an average temperature of 1.4°C. September through November offer the most consistent VFR weather, with relatively stable wind conditions averaging 7.3 knots from a northerly direction.
Notable Features
Located at a high elevation of 6,990 feet, Miley Memorial Field presents unique challenges for aircraft performance and altitude-related operations. The airport features two distinct runways: a 3,300-foot grass runway (08/26) and a longer 6,803-foot asphalt runway (13/31), providing flexibility for different aircraft types and operational needs. Both runways demonstrate 100% favorable wind alignment, with modest average crosswind conditions.
Approach Considerations
Wind data indicates northerly prevailing winds with 21.3% calm periods, which allows pilots flexibility in runway selection. The 13/31 runway, being longer and paved, is likely preferred for most aircraft operations. Pilots should anticipate potential wind variations and be prepared for high-altitude airport characteristics, with careful attention to aircraft performance calculations given the elevation and temperature ranges.
