Recognizing the importance of legislation and regulations of the civil aviation sector, King Abdulaziz oversaw four aviation regulatory acts in 1946, namely, the airport tariffs system, land and aircraft transit system, airports construction and air navigation system.  And in 1953, a royal decree was issued approving the integrated civil aviation system, which included a number of articles regulating air traffic in the territory of the Kingdom and its airports. Before King Abdulaziz passing and by the end of 1954, the Kingdom of Saudi Arabia owned (32) aircraft, of which (10) were DC-3, five Bristol 170, seven DC-4 and ten Convair 340. After the Kingdom received its first civilian airplane mentioned above, King Abdulaziz ordered the establishment of a number of dirt runways in various parts of the Kingdom, led by runways in Riyadh, Dhahran, Al Hawiya in Taif, Al Hafouf, Buraidah, Jazan, Al kharj and Afif.  The first flight that King Abdulaziz took was on the 4th of October, 1945, directly from Afif to Al Hawiya in the city of Taif.  More runways were established thereafter in a number of region around the Kingdom, same while two more aircraft were added to the fleet.  Some of these runways were the cornerstones for new airports with facilities that were adequate for that era.  Regularly scheduled flights were operated by Saudi Arabian Airlines thereafter. --More 11:02 LOCAL TIME 08:02 GMT 0004 www.spa.gov.sa/w1176593
