The control tower will house the Apron Control Centre for the Airport Authority, Forecasting Office for the Royal Observatory, and equipment room and control cab for the Civil Aviation Department.
Apart from the Air Traffic Control Complex and Tower, Mr Yuen added, the Architectural Services Department was also responsible for the design and management of the building works for other government facilities for the new airport.
These include the fitting out of Government facilities in the Passenger Terminal Building and the Air Cargo Building, and the construction of the Air Mail Centre, Government Flying Services Headquarters, police and fire stations, Civil Aviation Department radar stations and Royal Observatory meteorological facilities.
The media representatives were also briefed on the air traffic equipment and the Automatic Weather Station by the Deputy Air Traffic General Manager of the Civil Aviation Department, Mr Alex Au, and the acting Senior Scientific Officer of the Royal Observatory, Mr W. T. Wong.
Mr Au said the Air Traffic Control Centre on the sixth floor of the complex would house both the Approach and Area Control Units which provide services to aircraft landing at and taking off from Chek Lap Kok Airport as well as aircraft flying over Hong Kong.
Air traffic controllers working at the new centre will be using a range of sophisticated electronic systems including an efficient Speech Processing System which will be installed for communication with pilots and neighbouring air traffic control centres.
On the top of the Control Tower, Mr Au added, a Surface Movement System would be used by controllers to monitor aircraft movements on the ground, particularly during poor weather conditions or at night.
To enhance the radar coverage at Chek Lap Kok, a medium range radar system is being installed at Tai Mo Shan and a short range radar system at Sha Chau, five kilometres northwest of Chek Lap Kok.
To provide navigation guidance to aircraft, Doppler VHF Omni-directional Range and Distance Measuring Equipment are being installed at Siu Mo To and Lung Kwu Chau. A Microwave Link station has already been built at northeast Lantau to relay radar signals, air and ground communication messages and equipment remote control and indication signals between off-airport equipment stations and the Air Traffic Control Centre.
