Prince Mohammad Bin Abdulaziz Airport lies in the temperate mid-latitudes at 24.55° N, 39.71° E, on Asia/Riyadh time (UTC+3).
Prince Mohammad Bin Abdulaziz Airport has 2 runways. The longest, 17/35, measures 14,222 ft by 197 ft, which puts the field in the full-length intercontinental category: a fully loaded Boeing 777 or Airbus A350 can depart for the far side of the world. The surface is asphalt. Both are lit for night operations.
Runway 17/35 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.
The runways are not interchangeable. 18/36 is 10,039 ft against 17/35's 14,222 ft, a difference of 4,183 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
