Mactan Cebu International Airport lies in the tropics at 10.31° N, 123.98° E, on Asia/Manila time (UTC+8). 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.
Mactan Cebu International Airport has 2 runways. The longest, 04R/22L, measures 10,860 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. Surfaces vary across the field (asphalt, concrete). 1 of the 2 carry runway lighting.
Runway 04R/22L 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. 04L/22R is 8,399 ft against 04R/22L's 10,860 ft, a difference of 2,461 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
