Weather Briefing

VFR

Mariscal Sucre International Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 30,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 30000 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 11°C (52°F) with a dewpoint of 11°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Patches Fog. Expect variable wind speeds ranging from 3 to 14 knots. Temporary MVFR conditions are forecast with Patches Fog between 09:00Z and 12:00Z. Temporary MVFR conditions are forecast between 20:00Z and 23:00Z.

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 Mariscal Sucre International Airport

Overview

Mariscal Sucre International Airport serves as the primary international airport for Quito, Ecuador, located at an impressive elevation of 7,841 feet mean sea level. As a large airport situated in the capital city, it handles significant commercial and passenger traffic for the region.

Flying Conditions

The high-altitude location of 7,841 feet MSL presents unique atmospheric challenges for pilots, including reduced air density and potential performance limitations for aircraft. Pilots should anticipate thinner air conditions that will affect aircraft performance, climb rates, and engine efficiency during operations.

Notable Features

The airport features a single runway (18/36) with a substantial length of 13,445 feet, constructed with concrete (CON) surface. Its geographic coordinates at -0.125399, -78.354306 place the airport in the mountainous terrain of the Ecuadorian Andes, which introduces complex topographical considerations for approach and departure procedures.

Approach Considerations

Given the single runway's orientation of 18/36, wind conditions and terrain will significantly influence approach strategies. Pilots must be prepared for potential wind shear, altitude-related performance constraints, and the need for precise navigation in the mountainous environment surrounding Quito.
