Oecusse Route of the Sandalwood International Airport lies in the tropics at 9.20° S, 124.34° E, on Asia/Dili time (UTC+9). 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.
Oecusse Route of the Sandalwood International Airport has 1 runway. The longest, 09/27, measures 7,218 ft by 148 ft, which puts the field in the narrowbody standard category: the A320 and 737 families are at home here; widebodies would be tight. The surface is asphalt. It is lit for night operations.
At 0 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.
