Weather Briefing

VFR

Longtan Air Base is currently reporting visual flight rules (VFR) conditions with broken clouds at 8,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the south-southwest (200°) at 9 knots. Runway 22 is favored with a 8-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 8000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 22°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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: Showers Rain. Expect variable wind speeds ranging from 5 to 18 knots. Temporary VFR conditions are forecast between 12:00Z and 17:00Z. Temporary MVFR conditions are forecast with Showers Rain between 00:00Z and 06:00Z. Temporary IFR conditions are forecast with Showers Rain between 08:00Z and 12:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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.
