Tunis Carthage International Airport lies in the temperate mid-latitudes at 36.85° N, 10.23° E, on Africa/Tunis time (UTC+1).
Tunis Carthage International Airport has 2 runways. The longest, 01/19, measures 10,499 ft by 148 ft, which puts the field in the long-haul capable category: widebodies operate comfortably, though the very longest sectors may need a payload trade. The surface is asphalt. Both are lit for night operations.
Runway 01/19 is aligned roughly north/south, 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.
