Cognac-Châteaubernard (BA 709) Air Base

Cognac-Châteaubernard (BA 709) Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the FR AIP for current access procedures and restrictions.

Overview

Cognac-Châteaubernard Air Base (BA 709) is a medium-sized airport located near the city of Cognac in southwestern France. Situated at 102 feet above mean sea level, the base serves military and potentially civilian aviation operations with two substantial runways: a 7,949-foot primary runway (05/23) and a 5,951-foot secondary runway (08/26).

Flying Conditions

The airport experiences predominantly favorable VFR conditions 68.8% of the time, with moderate visibility averaging 10 statute miles. Temperature ranges from -9°C to 32°C, creating diverse seasonal flying environments, with September, October, and December offering the most consistent VFR conditions. Wind patterns are predominantly southerly at an average of 7.8 knots, with occasional gusts up to 27 knots.

Notable Features

Both runways demonstrate exceptional wind alignment, with 100% favorable wind coverage. The primary runway (05/23) experiences an average crosswind of 4.7 knots, while the secondary runway (08/26) sees slightly higher crosswind conditions at 5.3 knots. Fog occurs in 5.9% of observations, which pilots should consider during planning, particularly during transitional seasons.

Approach Considerations

Pilots should anticipate predominantly southerly winds when planning approaches, with a high probability of VFR conditions. The extensive runway lengths provide flexibility for various aircraft types, and the low elevation minimizes significant terrain considerations. Given the consistent wind patterns, either runway can be confidently selected based on current meteorological conditions.
