SITA has received a contract for the implementation of its air-to-ground data link service for the Jakarta Flight Information Region (FIR), which will offer improved air-to-ground communications within Indonesian airspace.
SITA's data link service will replace the existing voice services, which will allow airline crews and controllers to exchange messages associated with air traffic control, including en route services such as automatic dependent surveillance (ADS) and controller-pilot data link communications (CPDLC) services.
Under the end-to-end communications infrastructure agreement, SITA will be responsible for providing a dual redundant ADS-CPDLC ground workstation, a data link server and an ADS CPDLC test system to promote future air navigation systems (FANS) in the Jakarta FIR.
As part of the project, the air traffic controllers are currently working on preparing internal operational procedures and are undergoing ATC operational training, which will be followed by operational trial of ADS/CPDLC.
SITA FANS services would improve controller-to-pilot communications based on simple and identical pre-formatted message elements and position-tracking of aircraft, while offering safe and efficient air traffic operations.
SITA Asia Pacific Aircraft Services head Katrina Korzenowski said that over the last five years, the Indonesian domestic market for air travel has nearly doubled as airlines have expanded and low-cost airlines have started up.
"With growth in Indonesia and throughout the Asia Pacific region, voice communication will become increasingly congested," Korzenowski said. "That's why the new data link services are so important."
SITA's service and systems can support both long-haul and short-haul versions of CPDLC.
Globally, long haul aircraft implement a FANS version of CPDLC complying with International Civil Aviation Organization's (ICAO) technical standards for the future of air traffic, while short haul aircraft deploy Aeronautical Telecommunications Network (ATN) version of CPDLC.
Eastern Indonesia's Ujung Pandang FIR has already implemented FANS, while SITA's other data link service users include ANSPs in Asia Pacific regions, such as Singapore, Malaysia, Myanmar, India, Sri Lanka, Maldives, Philippines, Australia and Fiji.
