Weather Briefing

IFR

Alas Leuser Airport is currently reporting instrument flight rules (IFR) conditions with scattered clouds at 1,700 feet and 4.5 km visibility.

Wind Analysis

Winds are from the west-northwest (290°) at 6 knots. Runway 33 is favored with a 5-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is reduced to 4.5 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. No ceiling exists. Cloud layers reported: few at 1,600 ft (CB), scattered at 1,700 ft. Caution: cumulonimbus (thunderstorm) clouds reported at 1,600 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 25°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 24 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: Haze, Light Thunderstorm Rain. Temporary IFR conditions are forecast with Light Thunderstorm Rain between 18:00Z and 20:00Z.

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 Alas Leuser Airport

Overview

Alas Leuser Airport serves the Kutacane region in Indonesia, situated at an elevation of 419 feet above mean sea level. As a medium-sized airport located at coordinates 3.391456, 97.863726, it provides essential aviation infrastructure for the local area and supports regional transportation needs.

Flying Conditions

The airport's moderate elevation and tropical location suggest potential for variable weather conditions typical of Indonesian mountainous regions. Pilots should anticipate potential humidity, thermal variations, and localized weather phenomena that can impact visibility and wind conditions around the 5,358-foot asphalt runway.

Notable Features

The single runway (15/33) is oriented in a northwest-southeast direction, which may interact with local terrain and wind patterns. The surrounding geography appears to be mountainous, which could introduce complex local wind dynamics and potential turbulence during approach and departure phases.

Approach Considerations

Runway 15/33 offers a substantial 5,358-foot asphalt surface, providing adequate length for most regional aircraft operations. Given the airport's mountainous location, pilots should prepare for potential terrain-influenced wind shear and be prepared to conduct careful wind assessments during arrival and departure procedures.
