Expansion of Aeronautical felecommunications Capability at

Kai Tak Airport

I think I ought to amplify and clarify several points in our Saving Despatch 197 of 27th February in which we sought £235,200 from Colonial Development and Welfare Fund by way of a 50% contribution to the cost of a

Surveillance Radar and an Instrument Approach System for Runway 13 at Kai Tak.

2.

X?

First, as regards the new radar referred to at para. 4(b) for the control of arriving and departing aircraft. In view of future traffic movements, it will be essential to achieve the minimum safe separation between aircraft down to limiting meteorological conditions. Kai Tak has been unable to provide such radar control in the past, due to the limitations of present radar equipment. The higher perform- ance aircraft that are, and will be coming into service, require a radar installation which reflects the development that has taken place since the $264 was purchased. The new approach radar will not have a secondary or stand-by role as may be implied in para. 5.

3.

With the new radar, the $264 on its present site will become redundant. However, with certain modifications and resiting at Mount Parker, it will perform the following functions:

(a)

(b)

@

radar coverage of the terminal area to expedite aircraft climbing and descending;

medium/long range radar information in the event of a failure of the R.A.F. radar;

(c) approach/departure radar service (within the known

limitations of the equipment) in the event of the non-availability of the new approach radar.

The resiting of the $264 and the provision of a new radar will mean that the surveillance radar facilities in Hong Kong will have the necessary level of performance and reliability.
