aircraft is Mount Kellet; it would be impracticable to clear doparting aircraft to the same beacon initially dua totho rostrictions then suffered by both arrivals and departures.

iii) track: 125°- 190° from Mount Kellet would be unavailable to

deparing aircraft due to thepolitical constraint imposed by th Lama Islands.

(b) The use of the Cheung Chau TVOR/DME by aircraft departing from

runway 31s an essential element of the organisation of the system satisfies the following interdependent functions

i) the initial flight path of the aircraft after take-off from runwa; 31 is such that overflight of Choung Chau does not requi, e intricate manouevring or positioning by the aircraft, the facility is in fact on-route;

ii) aircr: ft doparting to the south-west may follow a track which

proco: urally soparates them from aircraft arriving from the cast: iii) route for departing aircraft can be positioned away from areas

required for the soquencing of arriving aircraft, thus allowing reduced penalties to Operators in terms of delays and profile interi uptions.

(a)The standard departure routes based upon the Cheung Chau TVOR/DME

tre designed to take departing airerait elver of areas that are cssentially used by arrivals in a remor that minimizoc. penalties to both arrivals and departures. Accurate track and distance informatio› from Cheung Chat, applied to routine procedures, will maint in the concept of pilot navigation.

(b)There will be basically four Standard Departure Procedures for air-

craft departing from runway 31, with minor variations included for specific routing:-

i) airer ft departing to the south west will leave Cheung Chau

on an assigned radial which is maintained until a distance of 40 n.m. at which point the aircraft will establish en the a signed climb radial and be cleared to climb above Fligh Level 150.

ii) aircr. It doparting to the east in traffic conditions where

there are no aircraft inbound from the east will route direct on to their assigned climb radial,

11). airer. ft departing to the east and south-east, who are in

confl with inbornds from those directions, will loave Chut Chan on the 100PCR radial to a point 20 n..frem thechangChau DMB, The aircraft will tion track 070" to inept the assigned climb radial, maintaining flight Jewel 150 until estallWled on that radial.
