Osan Air Base

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

Overview

Osan Air Base is a medium-sized airport located in Pyeongtaek, South Korea, serving primarily military aviation operations. Situated at 38 feet above mean sea level, the base features two parallel concrete runways, each 9,004 feet long, capable of handling significant aircraft traffic. Its strategic location supports regional military and potential international aviation needs.

Flying Conditions

Weather conditions at Osan Air Base demonstrate substantial variability, with Visual Flight Rules (VFR) predominating at 66.7% of observations. The airport experiences winds primarily from the east at an average of 5.9 knots, with temperatures ranging from -13°C to 31°C. Pilots can expect good visibility averaging 7.9 statute miles, with minimal periods of restricted visibility (fog occurs in only 1.4% of observations).

Notable Features

The airport's twin parallel runways (09L/27R and 09R/27L) offer consistent operational flexibility with identical 9,004-foot lengths. Both runways demonstrate 100% favorable wind alignment and minimal average crosswind of 2.8 knots. The relatively low elevation of 38 feet MSL and geographic positioning provide generally stable approach conditions.

Approach Considerations

January, November, and December represent the most consistently favorable VFR months for operations. With easterly winds prevailing and calm conditions occurring 30.8% of the time, pilots can typically expect stable approach conditions. The runways' similar characteristics and favorable wind patterns provide predictable landing and takeoff opportunities across most meteorological conditions.
