To
comply with the Global Implementation Plan of the ICAO
for the satellite-based CNS/ATM systems, a special and
dedicated project team was set up in January 2000 to work
on the transition from the terrestrial-based to the new
satellite-based systems.
Given the scale and complexity of the CNS/ATM systems,
the project will be implemented in three phases as follows:
Study
Phase - Systems Study and Analysis (1999-2013)
Trial
Phase - CNS/ATM Trial and Evaluation (2000-2018)
Implementation
Phase - CNS/ATM Implementation and Transition (2001-2025)
To facilitate the progress of the project, a Hong Kong
CNS/ATM Committee was set up in March 2000. Chaired by
CAD, the Committee comprises representatives from the
International Air Transport Association (IATA), International
Federation of Air Line Pilots' Associations (IFALPA),
CPA, Hong Kong Observatory and telecommunications services
providers. It discusses, reviews and coordinates various
issues relating to the study, trial and subsequent implementation
of the CNS/ATM systems in Hong Kong.
Detailed
investigation work on the various elements of the CNS/ATM
systems has commenced. Trials on the following CNS/ATM
systems have been completed satisfactorily and put into
operational use :
- Digital Automatic Terminal Information Service (D-ATIS)
and Digital VOLMET
- Pre-Departure Clearance (PDC) delivery via data link
- Aeronautical Telecommunications Network (ATN) link between
Hong Kong and Bangkok, which was the first of such link
put into operational use in the Asia-Pacific Regions
- Air Traffic Services Inter-facility Data Communication
(AIDC) between Hong Kong and Sanya.
Apart from the above operational CNS/ATM systems, trials/evaluations
on other prioritised systems are being conducted including
:
- Advanced Surface Movement Guidance and Control System
(A-SMGCS)
- Arrival Metering and Sequencing (AMS) System
- 2-way Data-Link PDC
Evaluations and/or implementation of other CNS/ATM systems
such as ATS Message Handling System (AMHS), Global Navigation
Satellite System (GNSS), Automatic Dependent Surveillance-Broadcast
(ADS-B) system will be conducted in line with the ICAO
CNS/ATM development plan.
