Andersen Air Force Base

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

Overview

Andersen Air Force Base is a medium-sized airport located in Yigo, Guam, serving as a critical military aviation facility in the Pacific region. Situated at 627 feet above mean sea level with coordinates 13.584000, 144.929998, the base features two substantial parallel runways capable of handling large military and transport aircraft. Its strategic location in the western Pacific makes it a key operational and logistics hub for military aviation.

Flying Conditions

Weather conditions at Andersen AFB demonstrate predominantly favorable flying conditions, with 90.6% of observations supporting VFR or MVFR flight rules. The prevailing winds come from the east at an average of 11.1 knots, with temperatures consistently ranging between 23°C and 31°C. Pilots can expect excellent visibility averaging 9.5 statute miles, with minimal instances of restricted visibility or fog.

Notable Features

The airport features two parallel runways: 06L/24R at 10,558 feet and 06R/24L at 11,185 feet, both constructed with PEM (Possible Explanation Missing) surface. Both runways demonstrate 100% favorable wind alignment, with an average crosswind of just 4.5 knots. The consistent wind patterns and substantial runway lengths provide excellent operational flexibility for various aircraft types.

Approach Considerations

Optimal flying months are September, October, and December, offering the most consistent weather conditions. The east-prevailing winds at 90 degrees create predictable approach and departure scenarios for both runways. With calm conditions occurring only 1.8% of the time and maximum winds reaching 30 knots, pilots should anticipate generally stable approach conditions with minimal wind-related challenges.
