Weather Briefing
IFRJASDF Ashiya Air Base is currently reporting instrument flight rules (IFR) conditions with overcast skies at 4,100 feet and 4.9 km visibility.
Wind Analysis
Winds are from the east (100°) at 15 knots. Runway 12/30 is favored with a 14-knot headwind and 5-knot crosswind component. Student pilots and low-time aviators should exercise caution.
Visibility & Ceiling
Visibility is 4.9 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 500 feet AGL (broken). Only precision approaches may be usable depending on minimums.
Temperature & Moisture
Temperature is 14°C (57°F) with a dewpoint of 13°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.
Forecast Outlook
The TAF forecast covers the next 30 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Showers Rain, Showers Rain, Mist, Light Showers Rain, Mist. Temporary IFR conditions are forecast with Showers Rain, Mist between 18:00Z and 00:00Z. Temporary IFR conditions are forecast with Light Showers Rain, Mist between 00:00Z and 04:00Z. Temporary IFR conditions are forecast with Light Showers Rain, Mist between 04:00Z and 09:00Z.
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 JASDF Ashiya Air Base
JASDF Ashiya Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the JP AIP for current access procedures and restrictions.
Overview
JASDF Ashiya Air Base is a medium-sized military airport located in Ashiya, Japan, with an elevation of 98 feet above mean sea level. Situated at coordinates 33.883099, 130.653000, the base serves as a strategic Japanese Air Self-Defense Force (JASDF) installation. The airport primarily supports military aviation operations in the southwestern region of Japan.
Flying Conditions
The airport's low elevation at 98 ft MSL suggests relatively stable atmospheric conditions typical of coastal Japanese terrain. Pilots can expect moderate climate variations with potential maritime influences from the nearby coastal region. Wind patterns and seasonal changes will impact flight operations, particularly on the single runway 12/30 measuring 5,380 feet in asphalt surface.
Notable Features
RJFA features a single runway (12/30) oriented in a northeast-southwest direction, providing flexibility for different wind conditions. The asphalt surface runway extends 5,380 feet, accommodating medium-sized military aircraft typical of JASDF operations. The airport's geographical location near the coast may introduce specific wind and visibility considerations for approaching aircraft.
Approach Considerations
Runway 12/30's substantial 5,380-foot length provides reasonable landing and takeoff capabilities for military aircraft. Pilots should anticipate potential crosswind components given the coastal location and single runway orientation. Standard military approach protocols and local air traffic control procedures will govern arrival and departure operations at this JASDF installation.
