About Chiayi Airport

Overview

Chiayi Airport serves as a medium-sized airport located in Shuishang, Taiwan, positioned at coordinates 23.462577, 120.390544. The airport sits at an elevation of 85 feet mean sea level (MSL) and provides essential aviation infrastructure for the region. Its three runways offer substantial capacity for various aircraft operations.

Flying Conditions

Situated in central Taiwan, Chiayi Airport experiences typical subtropical climate conditions that can produce variable weather patterns. The airport's moderate elevation at 85 ft MSL suggests relatively stable atmospheric conditions, though pilots should anticipate potential seasonal humidity and precipitation variations. Temperature and wind characteristics will likely influence runway selection and approach strategies.

Notable Features

The airport features three distinct runways: an unspecified 18/36 runway, a 5,307-foot asphalted 18L/36R runway, and a substantial 10,007-foot concrete 18R/36L runway. This diverse runway configuration provides operational flexibility for different aircraft types and weights. The substantial length of the 18R/36L runway particularly accommodates larger aircraft and potentially supports complex operational requirements.

Approach Considerations

Runway orientation suggests north-south approaches with multiple parallel runway options. Pilots should carefully evaluate runway lengths and surface types when planning arrivals and departures. The concrete 10,007-foot runway offers the most extensive operational capability and likely represents the primary approach and landing surface for most aircraft movements.
