Good job the airport designers of CVF didn't read some of the posts here first.
"The French however, have decided not to let a simple matter like density altitude get in the way. By simply making the runway follow the slope of the mountain, and decreeing that takeoffs are downhill and landings uphill, gravity is used as a replacement for air molecules. Large twins and even four engine turboprops are able to takeoff and land on a runway which totals 535m (from the drop-off at the bottom to the mountain face at the top) a TODA or LDA which would be marginal if it was at sea level, and flat.
At Courchevel, with varying gradients along the length of the runway (to a maximum of 18.5% for the central 238m) the mere fact that the local QFE on a standard day would be 793mb is no obstacle either to take-off or to landing. It does however put paid once and for all to the argument about always landing on QFE. Just try winding off 6000' from your altimeter as you enter the circuit to see why..."
