Weather Briefing

VFR

Mariscal Sucre International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 4,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north (350°) at 17 knots. Runway 36 is favored with a 17-knot headwind and 3-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 4000 feet AGL (broken), well above standard VFR minimums. Caution: towering cumulus clouds reported at 3,000 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 23°C (73°F) with a dewpoint of 13°C, indicating moderate moisture conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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. Temporary VFR conditions are forecast between 20:00Z and 22:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.
