Shah Amanat International Airport lies in the tropics at 22.25° N, 91.81° E, on Asia/Dhaka time (UTC+6). 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.
Shah Amanat International Airport has 1 runway. The longest, 05/23, measures 9,646 ft by 148 ft, which puts the field in the widebody capable category: twin-aisle aircraft can use it, and narrowbodies have length to spare. The surface is concrete. 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.
At 12 ft the field is effectively at sea level, which is the friendliest case for aircraft performance: maximum lift, maximum thrust and the shortest takeoff runs an aircraft is capable of.
