KLIA aerotrain to undergo software upgrade after 20,000 operational hours

The KLIA aerotrain is set to undergo a software upgrade from midnight to 5am, as part of a scheduled maintenance to enhance its operational endurance and long-term performance. Malaysia Airports Holdings Bhd (MAHB) disclosed that the upgrade will be carried out in two phases, with aerotrain services temporarily suspended during the process.

The first phase, taking place from October 8 to 17, will involve field testing where the software update will be installed and tested under real operating conditions. This phase aims to verify the software's performance and functionality before undergoing a comprehensive independent safety assessment.

The second phase, scheduled from November 28 to December 1, will see the permanent deployment of the upgraded software on the aerotrain system once the results of the safety assessment are satisfactory. Throughout these upgrade and testing periods, bus services will operate to ensure uninterrupted transfers between the main terminal and satellite buildings, maintaining passenger convenience.

Since June, the KLIA aerotrain system has maintained an impressive 99.9% availability, completing 167,481 return trips and serving approximately 23.55 million passengers in the past one and a half years. MAHB's top priority is to ensure the aerotrain continues to provide reliable and smooth service for passengers at KLIA.

KLIA's chief operating officer, Adam Nicholas Wilson, emphasized that planned activities like this software upgrade are part of ongoing efforts to maintain the system's high level of performance and reliability for the long term.
