Frank Pais International Airport lies in the tropics at 20.79° N, 76.32° W, on America/Havana time (UTC-4). Tropical airports contend with heat and humidity, both of which thin the air and lengthen takeoff runs, and with convective storms that build fast in the afternoon.
Frank Pais International Airport has 1 runway. The longest, 05/23, measures 10,624 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. It is lit for night operations.
Runway 05/23 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. Every runway here shares that north-east/south-west alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
