OERK happens to be the easiest of the 3 major airports in KSA. Much better marked and easier to identify visually than Jeddah. ATC is more professional than JED or DHA.
ILS/DME to 15L/R, ILS/DME to 33L/R, VOR/DME to 15 L/R, VOR/DME to 33L/R.
WX is predominately CAVOK with light winds. Temps high for 6 months a year which do restrict TO weight.
In closing, RUH is an under utilized, well marked, well controlled, airport with 2 3300 meter runways with very little WX. Can you ask for more? What better place to go to especially if crew was unfamiliar.
