Weather Briefing

MVFR

Longtan Air Base is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,500 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north-northeast (30°) at 6 knots. Runway 04/22 is favored with a 6-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1500 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 23°C (73°F) with a dewpoint of 23°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expect variable wind speeds ranging from 5 to 18 knots. Temporary MVFR conditions are forecast between 12:00Z and 15:00Z. Temporary VFR conditions are forecast between 18:00Z and 00:00Z. Temporary VFR conditions are forecast between 06:00Z and 12:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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 Longtan Air Base

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

Overview

Longtan Air Base is a medium airport located in the Taoyuan region of Taiwan, positioned at coordinates 24.853588, 121.236392. The airfield serves as an important regional aviation facility with a strategic location in northern Taiwan. Its elevation of 790 feet above mean sea level provides stable terrain for aviation operations.

Flying Conditions

The airport's elevation at 790 ft MSL suggests a moderate terrain environment typical of Taiwan's northern regions. While specific seasonal weather data is not provided, pilots should anticipate potential variations in wind and visibility common to the area's subtropical climate. The single runway orientation (04/22) indicates potential wind exposure from different directions.

Notable Features

The airbase features a single runway measuring 3,260 feet long with an asphalt (ASP) surface. Its moderate length accommodates medium-sized aircraft operations, with potential limitations for larger commercial or military aircraft. The runway's 04/22 orientation suggests north-northeast and south-southwest approach/departure paths.

Approach Considerations

Given the runway's 04/22 orientation, pilots should prepare for approaches aligned with these cardinal headings. The 3,260-foot runway length requires careful planning for aircraft performance and weight considerations. Standard instrument approach procedures would likely involve navigating the terrain surrounding the Taoyuan region while maintaining awareness of the airport's moderate elevation.
