Two of the fastest growing airports in Southeast Asia plan to invest in new communications and navigational systems to cope with increasing air traffic. Malaysia’s Ministry of Transport (MMOT) said it will invest $212 million to build a new air traffic control center at Kuala Lumpur International Airport (KLIA) to replace the existing 20-year-old system at Sultan Abdul Aziz Shah Airport, 15 miles outside the city. In Manila, officials have committed $1.1 million to replace malfunctioning 18-year-old Doppler omni-directional radio range and distance-measuring equipment at Ninoy Aquino International Airport (NAIA) with a communication surveillance/air traffic management system.
Operations and Infrastructure of Kuala Lumpur International Airport
Air traffic controllers at Kuala Lumpur International Airport (KLIA) cannot carry out simultaneous dual-runway operations due to lack of so-called non-transgression-zone software, resulting in congestion in Malaysian airspace and a choke point for takeoff at KLIA. The airport’s pair of 13,000-foot-long runways can accommodate 32 arrivals and 36 departures per hour.
Airlines have lodged complaints about the excess fuel their airplanes burn while caught in departure queues, at times waiting for as long as 25 to 30 minutes before ATC can clear them for takeoff.
