About Lackland Air Force Base

Lackland Air Force Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the US AIP for current access procedures and restrictions.

Overview

Lackland Air Force Base (KSKF) is a medium-sized airport located in San Antonio, Texas, at an elevation of 691 feet MSL. The base serves as a critical military aviation facility, situated in a region with diverse operational requirements. Its strategic location and substantial runway (15/33 at 11,550 feet) support various military and potentially joint aviation operations.

Flying Conditions

Pilots can expect predominantly VFR conditions, with 60.5% of observations reporting visual flight rules. Seasonal temperature variations are significant, ranging from -2°C to 38°C, with an average of 20.1°C. Wind conditions are typically from the south (180°) at an average of 6.7 knots, with calm periods occurring 20.1% of the time and maximum gusts up to 26 knots.

Notable Features

The airport's single runway (15/33) offers consistent wind alignment, with 100% favorable wind conditions. Average crosswinds are relatively mild at 3.7 knots, providing comfortable approach and landing parameters. The surrounding terrain and San Antonio's geographic characteristics contribute to the airport's stable operational environment.

Approach Considerations

September through November represent the most consistent VFR months, offering optimal flying conditions. With an average visibility of 9.3 statute miles and minimal low visibility events (fog present only 1.5% of observations), pilots can anticipate generally clear approach conditions. The long runway and predictable wind patterns provide flexibility for various aircraft types and operational requirements.
