d) determining the location of aircraft and vehicles on the manoeuvring area;
e) providing directional taxi information to aircraft when requested by the pilot or deemed necessary by the controller. Except under special circumstances, e.g. emergencies, such information should not be issued in the form of specific heading instructions; and
f) providing assistance and advice to emergency vehicles.
10.2.3 Identification of aircraft
10.2.3.1 Where SMR is used, aircraft may be identified by one or more of the following procedures:
a) by correlating a particular radar position indication with:
i) an aircraft position visually observed by the controller;
ii) an aircraft position reported by the pilot; or
iii) an identified radar position indication displayed on a surveillance radar display;
b) by transfer of radar identification when authorized by the appropriate ATS authority; and
c) by automated identification procedures when authorized by the appropriate ATS authority.
Rules of the Air and Air Traffic Services (PANS-RAC)
11. Use of radar in the flight information service
Note.— The use of radar in the provision of flight information service does not relieve the pilot-in-command of an aircraft of any responsibilities, including the final decision regarding any suggested alteration of the flight plan.
11.1 Functions
11.1.1 The information presented on a radar display may be used to provide identified aircraft with:
a) information regarding any aircraft observed to be on a conflicting path with the radar-identified aircraft and suggestions or advice regarding avoiding action;
b) information on the position of significant weather and, as practicable, advice to the aircraft on how best to circumnavigate any such areas of adverse weather (see 6.9.2, Note);
c) information to assist the aircraft in its navigation.
11.1.2 Radar air traffic advisory service. When radar is used in the provision of air traffic advisory service, the procedures in Section 2 for the use of radar in the air traffic control service shall be applied subject to the conditions and limitations governing the provision of air traffic advisory service, as set forth in Part VII, 1.4.
PART VII. FLIGHT INFORMATION SERVICE
AND ALERTING SERVICE
1. Flight information service
1.1 Recording and transmission of information on the progress of flights
1.1.1 Information on the actual progress of flights, including those of heavy or medium unmanned free balloons, under neither air traffic control service nor air traffic advisory service shall be:
a) recorded by the air traffic services unit serving the flight information region within which the aircraft is flying in such a manner that it is available for refe-rence and in case it is requested for search and rescue action;
b) transmitted by the air traffic services unit receiving the information to other air traffic services units concerned, when so required in accordance with Part VIII, 2.2.
1.2 Transfer of responsibility for the provision of flight information service
1.2.1 The responsibility for the provision of flight information service to a flight normally passes from the appropriate ATS unit in a flight information region to the appropriate ATS unit in the adjacent flight information region at the time of crossing the common flight information region boundary. However, when co-ordination is required in accordance with Part VIII, 2.1, but communication facilities are inadequate, the former ATS unit shall, as far as practicable, continue to provide flight information service to the flight until it has established two-way communication with the appropriate ATS unit in the flight information region it is entering. 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：Rules of the Air and Air Traffic Services(88)
