About Los Alamitos Army Air Field

Los Alamitos Army Air Field 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

Los Alamitos Army Air Field serves as a medium-sized airport located in Los Alamitos, California, situated at 32 feet above mean sea level. The field supports military aviation operations with three runways, offering robust infrastructure for diverse aircraft types. Its strategic location in Southern California provides critical aviation capabilities for regional military and potential support missions.

Flying Conditions

Weather conditions at KSLI demonstrate significant variability, with Visual Flight Rules (VFR) prevailing 61.8% of the time. Pilots can expect predominantly southerly winds averaging 5.5 knots, with calm conditions occurring 47.7% of observations. Temperature ranges from 3°C to 34°C, creating generally stable atmospheric conditions throughout the year.

Notable Features

The airport features three runways with substantial length variations: two primary runways at 5900 and 8000 feet of paved surface, and a shorter 2500-foot auxiliary runway. The geographic positioning enables flexible operations with consistent wind alignment, as all runways demonstrate 100% favorable wind conditions. Low elevation and coastal proximity contribute to predictable meteorological patterns.

Approach Considerations

All three runways offer favorable wind alignments with minimal crosswind challenges, averaging between 3-3.6 knots. Visibility typically exceeds 7.3 statute miles, with only 4.7% of observations presenting visibility below 3 miles. September, October, and January represent the most consistent VFR months, providing optimal approach and departure conditions for pilots.
