Weather Briefing

IFR

Jungwon Air Base/Chungju Airport is currently reporting instrument flight rules (IFR) conditions with few clouds at 500 feet and 4.8 km visibility. Note: This observation is 840.4 hours old and conditions may have changed.

Wind Analysis

Winds are from the east (80°) at 1 knots.

Visibility & Ceiling

Visibility is reduced to 4.8 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. No ceiling exists. Cloud layers reported: few at 500 ft.

Temperature & Moisture

Temperature is 4°C (39°F) with a dewpoint of 4°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Jungwon Air Base/Chungju Airport

Jungwon Air Base/Chungju Airport 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

Jungwon Air Base/Chungju Airport is a medium airport located in Gimseang-ro, South Korea, situated at an elevation of 281 feet MSL. The airport features two substantial concrete runways: 18L/36R at 9,021 feet and 18R/36L at 9,330 feet, providing significant operational flexibility for various aircraft types.

Flying Conditions

Weather conditions at RKTI demonstrate significant variability, with instrument flight rules (IFR) and low instrument flight rules (LIFR) conditions prevalent in 56.7% of observed METARs. Temperature ranges from -6°C to 29°C, with an average of 9.2°C, and wind patterns predominantly from the north at an average of 3.2 knots. Fog occurs in 16.8% of observations, with October, January, and September offering the most consistently favorable visual flight conditions.

Notable Features

The airport's dual parallel runways (18L/36R and 18R/36L) both demonstrate 100% favorable wind alignment, with minimal average crosswind of 2.2 knots. Its relatively low elevation of 281 feet MSL and geographic location suggest a relatively mild terrain environment for aviation operations.

Approach Considerations

Pilots can expect consistently aligned runway configurations with minimal crosswind challenges. The extensive runway lengths of 9,021 and 9,330 feet accommodate a wide range of aircraft, while the prevailing northern wind patterns provide predictable approach conditions. Visibility averages 10 statute miles, with calm wind conditions occurring in 29.4% of observations.
