Gimhae International Airport lies in the temperate mid-latitudes at 35.18° N, 128.94° E, on Asia/Seoul time (UTC+9).
Gimhae International Airport has 2 runways. The longest, 18R/36L, measures 10,499 ft by 197 ft, which puts the field in the long-haul capable category: widebodies operate comfortably, though the very longest sectors may need a payload trade. Surfaces vary across the field (asphalt, concrete). Both are lit for night operations.
Runway 18R/36L is aligned roughly south/north, 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.
At 6 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.
