The Thirtieth Meeting of the ICAO RVSM Implementation Task Force
(RVSM/TF/30)
Bangkok, Thailand, 12 – 16 March 2007
Agenda Item 2: Operational Considerations
Agenda Item 3: Issues Relating to Airworthiness and Approval of Aircraft
Agenda Item 4: Safety and Airspace Monitoring Considerations
REVIEW OF DRAFT AIP AMENDMENT FOR RVSM IMPLEMENTATION
(Presented by China)
SUMMARY
This paper provides the draft Aeronautical Information Publication
(AIP) Supplement for RVSM implementation in China.
Action by RVSM/TF/30 is in paragraph 3.
1. INTRODUCTION
1.1 This Working Paper provides a draft AIP Supplement for meeting’s review. This
draft is applicable to the implementation of RVSM in Chinese FIRs.
2. DISCUSSION
2.1 The Secretariat of the ICAO RVSM Implementation Task Force undertook a mission
to Beijing, China on 14 and 15 February 2007 to coordinate in advance and prepare for the
RVSM/TF/30. China provided the Secretariat with the draft AIP Supplement for the RVSM
implantation. The Secretary reviewed the draft AIP Supplements and commented back to China.
China should finalize details on the policies and procedures for RVSM operations and publish the
corresponding AIP Supplements.
2.2 From the practical point for the easy reference, the flexibility to update if necessary
and the harmonization with the precedence with the other area, it is suggested to use the AIP
supplement format to disseminate the RVSM policy and procedures. The procedures applicable in
oceanic airspace were proposed to be deleted from the AIP supplement as the procedures have
become obsolete after the strategic offset procedures were introduce in 15.2.4 of the Procedures for
Air Navigation Services – Air Traffic Management (PANS-ATM, Doc 4444) where if wake
turbulence needs to be avoided, one of the three available options (0, 1 or 2 NM right offset) may be
used.
3. ACTION BY THE MEETING
3.1 The meeting is invited to review the draft AIP supplement as in Attachment to this
paper.

中国国内空域缩小垂直间隔标准的政策和程序
RVSM Policy and Procedures in China Domestic Airspace
1.0 序言
1.1 国际民航组织(ICAO)第三次亚太
地区空中航行会议建议：在北大西洋地
区成功实施缩小的垂直间隔标准（
RVSM）之后，在亚洲和太平洋地区也
应当引入RVSM。这主要是因为航空
器营运人和空中交通服务(ATS)提供人
将获得巨大收益。ICAO 9574 号文件—
在FL291 和FL411(含)之间实施300 米
(1 000 英尺)的垂直间隔标准手册中包
含有对RVSM 的解释。
1.2 实行RVSM可获得的好处包括
：
(a) 采用了ICAO 支持的导航要求；
(b) 改善了空域的使用,有利于ATC
调解冲突;
(c) 对于接近最佳巡航高度的飞行，
节省燃油约1%；
(d) 减小地面延误。
1.3 内容
ICAO 亚太地区RVSM工作组已经
协调制订出本文件的基本内容。在本文
件的各段中论述了以下政策:
2.0 RVSM 空域的范围
3.0 航空器适航和运行审批和监督
4.0 空域安全评估与监测
5.0 ACAS II 与应答机的装备
6.0 RVSM 空域中的飞行程序
1.0 Introduction
1.1 The International Civil Aviation Organization (ICAO)
Third Asia/Pacific Regional Air Navigation Meeting
recommended that Reduced Vertical Separation Minimum
(RVSM) should be introduced in the Asia and Pacific region after
successful implementation in the North Atlantic region. This is
due to the significant benefits to be gained by aircraft operators
and air traffic services (ATS) providers. ICAO Document 9574,
Manual on Implementation of a 300m (1 000 ft) Vertical
Separation Minimum between FL 291 and FL 411 inclusive
contains an explanation of RVSM.
1.2 Benefits to be gained from RVSM include:
(a) Adoption of an ICAO endorsed navigation requirement;
(b)Improved utilization of airspace for ATC conflict
resolution;
(c) Fuel savings of ≈ 1% for flight closer to optimum cruise
altitude; and
(d) Reduction in ground delays.
1.3 Content
The ICAO Asia/Pacific RVSM Implementation Task Force has
harmonized the basic content of this document. The following
policies are addressed in the paragraphs of this document:
2.0 Identification of RVSM Airspace
3.0 Airworthiness and Operational Approval, and
Monitoring
4.0 Airspace Safety Assessment and Monitoring
5.0 ACAS II and Transponder Equipage
6.0 In-flight Procedures within RVSM Airspace

4.0 Airspace Safety Assessment and Monitoring
4.1 In order to conduct the airsapce safety assessment and
monitoring required by the ICAO Doc 9574, large height
deviation report will be collected. Information contained in the
collected reports will not be used for other purpose than the
airspace safety assessment and safety monitoring.
4.2 Applicable Airspace
Large height deviation occurences will be collected from the
entire airspace of Chinese FIRs.

Contingency scenarios.
The following paragraphs summarize pilot actions to mitigate the
potential for conflict with other aircraft in certain contingency
situations. They should be reviewed in conjunction with the
expanded contingency scenarios detailed on page 17, which
contain additional technical and operational detail.
*Scenario 1: The pilot is: 1) unsure of the vertical position of the
aircraft due to the loss or degradation of all primary
altimetry systems, or 2) unsure of the capability to
maintain cleared flight level (CFL) due to turbulence
or loss of all automatic altitude control systems.
飞行员应当：
The Pilot should:
可期待ATC：
ATC can be expected to:
在评估情况的同时保持CFL
Maintain CFL while evaluating the situation;
目视或参照ACAS(如果装备有)观察冲突活动
Watch for conflicting traffic both visually and by reference
to ACAS, if equipped;
如果认为必要，用以下方式警告附近航空器：
1) 充分使用外部灯光；
2) 在121.5 MHz 上（作为备份手段，可使用飞行员之
间的空对空VHF 频率123.45），广播位置、飞行
高度层和意图。
If considered necessary, alert nearby aircraft by
1) making maximum use of exterior lights;
2) Broadcasting position, FL, and intentions on 121.5 MHz
(as a back up, the VHF inter-pilot air-to-air frequency,
123.45MHz, may be used).
将情况和打算采取的行动告知ATC。可能采取的行动
包括：
Notify ATC of the situation and intended course of action.
Possible courses of action include:
获取飞行员的意图；发送重要交通情报。
Obtain the pilot's intentions and pass essential traffic
information.
1) 如果ATC 能够提供侧向、纵向或常规的垂直间隔，
保持CFL 和航线
1) 如果飞行员打算继续在RVSM 空域中飞行，评估交
通情况并确定可否为该航空器配备侧向、纵向或常
规的垂直间隔；如果可以，应用恰当的标准。
1) Maintaining the CFL and route provided that ATC can
provide lateral, longitudinal or conventional vertical
separation.
1) If the pilot intends to continue in RVSM airspace,
assess traffic situation to determine if the aircraft can
be accommodated through the provision of lateral,
longitudinal, or conventional vertical separation, and if

so, apply the appropriate minimum.
2) 如果航空器无法保持CFL 并且ATC 无法建立与其它
航空器足够的间隔，申请上升到RVSM 空域之上
或下降到它之下的ATC 许可。
2) Requesting ATC clearance to climb above or descend
below RVSM airspace if the aircraft cannot maintain
CFL and ATC cannot establish adequate separation
from other aircraft.
2）如果飞行员申请脱离RVSM 空域，如果可能，迅速
安排。
2) If the pilot requests clearance to exit RVSM airspace,
accommodate expeditiously, if possible.
3）如果无法保持足够的间隔并且不可能允许飞行员脱
离RVSM 空域的申请，告知附近其它航空器并继
续监视情况。
3) If adequate separation cannot be established and it is
not possible to comply with the pilot's request for
clearance to exit RVSM airspace, advise the pilot of
essential traffic information, notify other aircraft in the
vicinity and continue to monitor the situation.
4）将情况告知邻近的ATC 单位/扇区
4) Notify adjoining ATC facilities/sectors of the situation.
情形2: 一套主用高度测量系统失效或
失准（例：两套主用高度表相
差大于200 英尺）
Scenario 2: There is a failure or loss of accuracy of one primary
altimetry system (e.g., greater than 200 foot
difference between primary altimeters)
飞行员应当：
The Pilot should
对照检查备用高度表，证实主用高度表系统的准确性并告知ATC 失去冗余。如果不能证实主用高度表系统
的准确性，遵照前一情形中所列出的飞行员行动。

redundancy. If unable to confirm primary altimeter system accuracy, follow pilot actions listed in the preceding scenario.
