Václav Havel Airport Prague lies in the temperate mid-latitudes at 50.10° N, 14.26° E, on Europe/Prague time (UTC+2).
Václav Havel Airport Prague has 2 runways. The longest, 06/24, measures 12,189 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 concrete. Both are lit for night operations.
Runway 06/24 is aligned roughly north-east/south-west, 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. With 2 runways across 2 different headings, crews can pick whichever best suits the wind.
The runways are not interchangeable. 12/30 is 10,663 ft against 06/24's 12,189 ft, a difference of 1,526 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
