AIRFIELDS AT HONG KONG
Preliminary Summary of Essential
Factors drawn up by the Airfield kission
There is only one existing airfield at Hong Kong. called Kaitak. It has two runways. No. 1, NW/SE,
It is
1500 yards, which is the only one used, and No. 2, ENE/WSW, 1600 yards, which cannot be used for landing from the East owing to hills. It lies in a horseshoe of hills with extremely bad approaches from the WWW clockwise round to SSE. It is just operable for the Dakota, type of aircraft, but even for them is unpleasant. It is quite out of the question to
It is capable of slight use it for four-engined aircraft.
extension at heavy cost, but that in no way affects the approaches and still will not improve the problem as regards heavy four-engined aircraft.

Ping Shan, 23 miles 2. There are two other possibilities by road NW of Kowloon, and Deep Bay, 2 miles NW of Ping Shan. Ping Shan is the site which has been fully reported upon by Works, and preparations for the construction of which are far advanced. The essential differences between the two are
Deep Bay can make the better cost and time of construction, site, if the extra cost and extra delay can be accepted. The only way in which clear S. W. approaches can be obtained
Deep Bay is the only to any site is to cut away a hill. place where the topography lends itself to such a cut. is, perhaps, of interest to note that the C.-in-C. stated that he had himself in the first place suggested the removal of a hill at Deep Bay, but was told that it was impossible. It was, of course, impossible within the time period of six months which was apparently the time allowed on the date when the advice was given.

Prevailing winds are from NE to SW, or the reverse during the S monsoon. Records from the Royal Observatory at Kowloon show that for winds over 20 miles per hour Bust is the prevailing direction, but it seems to be generally agreed that the Kowloon observations are not strictly applicable to the Ping Shan aren and that winds from the NE tend to be recorded as E at Kowloon owing to th, high hills on the N and E of that place. hearing of the proposed runway at Ping Shan is about 24° true,
