13.2.6 All approaches regardless of weather conditions shall be radar-monitored. Control instructions and information necessary to ensure separation between aircraft and to ensure aircraft do not enter the NTZ shall be issued.
Note 1.— The primary responsibility for navigation on the ILS localizer course and/or MLS final approach track rests with the pilot. Control instructions and information are therefore issued only to ensure separation between aircraft and to ensure that aircraft do not penetrate the NTZ. Pilots are not required to acknowledge those transmissions unless specifically requested to do so.
Note 2.— For the purpose of ensuring an aircraft does not penetrate the NTZ, the aircraft is considered to be the centre of its radar position symbol. The provisions regarding radar separation also apply.
13.2.7 When an aircraft is observed to overshoot the turn-on or to continue on a track which will penetrate the NTZ, the aircraft shall be instructed to return immediately to the correct track.
13.2.8 When an aircraft is observed penetrating the NTZ, the aircraft on the adjacent ILS localizer course or MLS final approach track shall be issued with appropriate heading and altitude instructions in order to avoid the deviating aircraft.
13.2.9 Radar monitoring shall not be terminated until:
a) visual separation is applied; or
b) the aircraft has landed, or in case of a missed approach, is at least 2 km (1.0 NM) beyond the departure end of the runway and adequate separation with any other traffic is established.
Note.— There is no requirement to advise the aircraft that radar monitoring is terminated.
13.3 Suspension of independent parallel approaches to closely-spaced parallel runways
13.3.1 Independent parallel approaches to parallel runways spaced by less than 1 525 m but not less than 1 035 m between their centre lines shall be suspended under certain weather conditions, as prescribed by the appropriate ATS authority, including windshear, turbulence, downdrafts, crosswind and severe weather such as thunderstorms, which might otherwise increase ILS localizer course and/or MLS final approach track deviations to the extent that an unacceptable level of deviation alerts would be generated.
Note.— Guidance material relating to weather conditions is contained in the Manual on Simultaneous Operations on Parallel or Near-Parallel Instrument Runways (Doc 9643).*

13.4 Dependent parallel approaches
13.4.1 Dependent parallel approaches may be conducted to parallel runways provided:
a) the runway centre lines are spaced by the distance specified in Annex 14, Volume I;
b) the aircraft are making straight-in approaches;
c) suitable surveillance radar with a minimum azimuth accuracy of 0.3 degrees (one sigma) and update period of 5 seconds or less is available;
d) ILS and/or MLS approaches are being conducted on both runways;
e) aircraft are advised that approaches are in use to both runways (this information may be provided through the ATIS);
f) the missed approach track for one approach diverges by at least 30 degrees from the missed approach track of the adjacent approach; and
g) approach control has an override capability to aerodrome control.
13.4.2 A minimum of 300 m (1 000 ft) vertical or a minimum of 5.6 km (3.0 NM) radar separation shall be provided between aircraft during turn-on to parallel ILS localizer courses and/or MLS final approach tracks. 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(56)
