About Rennes-Saint-Jacques Airport

Overview

Rennes-Saint-Jacques Airport serves the Brittany region in northwestern France, located near the city of Rennes in Ille-et-Vilaine. As a medium-sized airport with an elevation of 124 feet MSL, it provides critical aviation infrastructure for regional and commercial operations. The airport features two asphalted runways capable of supporting diverse aircraft types.

Flying Conditions

Weather conditions at Rennes-Saint-Jacques demonstrate significant variability, with visual flight rules (VFR) conditions present 36.7% of the time and instrument conditions (IFR/LIFR) occurring 41.4% of observations. Temperature ranges from -6°C to 29°C, with an average of 10.3°C, indicating potential seasonal temperature challenges. Prevailing winds from the south (180°) average 7.8 knots, with occasional gusts up to 26 knots.

Notable Features

The airport's two runways offer flexibility for different wind conditions, with both 10/28 and 14/32 experiencing 100% favorable wind alignments. Crosswind components remain relatively moderate, averaging 5-5.6 knots across runways. The airport's location in Brittany suggests potential maritime weather influences and complex local terrain interactions.

Approach Considerations

Pilots should anticipate mixed meteorological conditions, with fog occurring in 13.4% of observations and average visibility around 10 statute miles. September through November represent the most consistently favorable VFR months. The longer runway 10/28 at 6,890 feet provides substantial landing and takeoff options for most aircraft types.
