9.1.1 Radar systems used in the provision of approach control service shall be appropriate to the functions and level of service to be provided.
9.1.2 Radar systems used to monitor parallel ILS approaches shall meet the requirements for such operations specified in Part IV.
9.2 Functions
9.2.1 The information presented on a radar display may be used to perform the following additional functions in the provision of approach control service:
a) provide radar vectoring of arriving traffic on to pilot-interpreted final approach aids;
b) provide radar monitoring of parallel ILS approaches and instruct aircraft to take appropriate action in the event of possible or actual penetrations of the no transgression zone (NTZ);
Note.— See Part IV, Section 13.
c) provide radar vectoring of arriving traffic to a point from which a visual approach can be completed;
d) provide radar vectoring of arriving traffic to a point from which a precision radar approach or a surveillance radar approach can be made;
e) provide radar monitoring of other pilot-interpreted approaches;
VI. Radar Services
f) in accordance with prescribed procedures, conduct:
i) surveillance radar approaches;
ii) precision radar (PAR) approaches; and
g) provide radar separation between:
i) succeeding departing aircraft;
ii) succeeding arriving aircraft; and
iii) a departing aircraft and a succeeding arriving aircraft.
9.3 General approach radar procedures
9.3.1 The appropriate ATS authority shall establish procedures to ensure that the aerodrome controller is kept informed of the sequence of arriving aircraft, as well as any instructions and restrictions which have been issued to such aircraft in order to maintain separation after transfer of control to the aerodrome controller.
9.3.2 Prior to, or upon commencement of, radar vectoring for approach, the pilot shall be advised of the type of approach as well as the runway to be used.
9.3.3 The radar controller shall advise an aircraft being radar vectored for an instrument approach of its position at least once prior to commencement of final approach.
9.3.4 When giving distance information, the radar controller shall specify the point or navigation aid to which the information refers.
9.3.5 The initial and intermediate approach phases of an approach executed under the direction of a radar controller comprise those parts of the approach from the time radar vectoring is initiated for the purpose of positioning the aircraft for a final approach, until the aircraft is on final approach and:
a) established on the final approach path of a pilot-interpreted aid; or
b) reports that it is able to complete a visual approach; or
c) ready to commence a surveillance radar approach; or
d) transferred to the precision radar approach controller.
9.3.6 Aircraft vectored for final approach should be given a heading or a series of headings calculated to close with the final approach track. The final vector shall enable the aircraft to be established in level flight on the final approach track prior to intercepting the specified or nominal glide path if an MLS, ILS or radar approach is to be made, and should provide an intercept angle with the final approach track of 45 degrees or less.
Note.— See Part IV, Section 13.2 concerning radar vectoring of independent parallel approaches.
9.3.7 Whenever an aircraft is assigned a radar vector which will take it through the final approach track, it should be advised accordingly, stating the reason for the vector.
9.4 Vectoring to pilot-interpreted final approach aid
9.4.1 An aircraft vectored to intercept a pilot-interpreted final approach aid shall be instructed to report when established on the final approach track. Clearance for the approach should be issued prior to when the aircraft reports established, unless circumstances preclude the issuance of the clearance at such time. Radar vectoring will normally terminate at the time the aircraft leaves the last assigned heading to intercept the final approach track. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：Rules of the Air and Air Traffic Services(83)
