Lyon Saint-Exupéry Airport lies in the temperate mid-latitudes at 45.73° N, 5.09° E, on Europe/Paris time (UTC+2).
Lyon Saint-Exupéry Airport has 2 runways. The longest, 17R/35L, measures 13,124 ft by 148 ft, which puts the field in the full-length intercontinental category: a fully loaded Boeing 777 or Airbus A350 can depart for the far side of the world. The surface is asphalt. Both are lit for night operations.
Runway 17R/35L is aligned roughly south/north, which is the clearest hint you get about the prevailing wind here: runways are built to face the wind that blows most often, because aircraft take off and land into it. Every runway here shares that south/north alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
The runways are not interchangeable. 17L/35R is 8,760 ft against 17R/35L's 13,124 ft, a difference of 4,364 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
