About Antonio B. Won Pat International Airport

Overview

Antonio B. Won Pat International Airport serves as the primary international gateway for Guam, located in Hagåtña. The airport is strategically positioned at 13.485000, 144.797282, with an elevation of 298 feet above mean sea level. As a large airport, it provides critical aviation infrastructure for the Pacific region, supporting both commercial and potential military aviation operations.

Flying Conditions

Guam's tropical maritime climate presents variable weather conditions for pilots, with potential for rapid atmospheric changes. The airport's significant runway length (12,015 ft and 10,014 ft) provides substantial operational flexibility across different meteorological scenarios. Pilots should anticipate potential tropical weather patterns typical to the Mariana Islands, including occasional convective activity and tropical maritime wind conditions.

Notable Features

The airport features two parallel asphalt runways (06L/24R and 06R/24L) with substantial length, enabling operations for wide-body aircraft and providing redundancy in runway selection. Its geographical position on Guam offers unique challenges related to Pacific island terrain, including potential wind shear and localized microclimatic variations. The 298 ft elevation suggests a relatively low-altitude airport environment with minimal terrain interference.

Approach Considerations

Runway orientation (06/24) suggests prevailing wind considerations from east-northeast to west-southwest directions. The extensive runway lengths provide multiple approach and departure options, with 12,015 ft and 10,014 ft offering significant margins for various aircraft performance envelopes. Pilots should prepare for potential oceanic approach dynamics typical of Pacific island airport environments.
