About Gral. Bernardo O´Higgins Airport

Overview

General Bernardo O'Higgins Airport serves the Chillan region in central Chile, positioned at an elevation of 495 feet MSL. As a medium-sized airport with a single runway (04/22) measuring 5,740 feet in asphalt, it supports regional aviation operations in this agricultural zone. The airport's location at coordinates -36.582500, -72.031403 provides strategic access to the surrounding Biobío region.

Flying Conditions

Pilots can expect predominantly favorable Visual Flight Rules (VFR) conditions, with 88.5% of observations supporting clear weather operations. The airport experiences consistent southwest winds averaging 7 knots, with occasional gusts up to 18 knots. Temperature variations are significant, ranging from 1°C to 37°C, with an average of 15.1°C, suggesting potential for dynamic thermal conditions during flight.

Notable Features

The airport's single runway (04/22) demonstrates excellent wind alignment, with 100% favorable wind coverage and minimal average crosswind of 2.4 knots. Visibility typically remains excellent, with an average of 10 statute miles and rare occurrences of restricted visibility. Seasonal patterns indicate December, January, and October offer the most consistent VFR flying conditions.

Approach Considerations

Runway 04/22 provides consistent wind conditions, making it suitable for most approach scenarios. Pilots should anticipate southwest prevailing winds and prepare for potential thermal variations, especially during summer months. The low frequency of instrument meteorological conditions (IFR/LIFR at 4.8%) suggests generally stable approach environments, with minimal risk of significant visibility restrictions.
