Editing Flight level (section)

==Metre flight levels==
The [[International Civil Aviation Organization]] (ICAO) has recommended a transition to using the [[International System of Units]] since 1979<ref>[https://www.icao.int/publications/Documents/9958_en.pdf International Civil Aviation Organization - Assembly Resolutions in Force (as of 8 October 2010) - Doc 9958 - Published by authority of the Secretary General]</ref><ref> Council action in pursuance of Assembly Resolution A22-18 adopted 23 March 1979: 
[..]to cover all aspects of air and ground operations; provision of standardized system of units based on the SI; identification of non-SI units permitted for use in international civil aviation; provision for termination of the use of certain non-SI units.</ref> with a recommendation on using metres (m) for reporting flight levels.<ref name="an05_cons">[https://aerosavvy.com/wp-content/uploads/2014/08/an05_cons.pdf International Civil Aviation Organization - International Standards and Recommended Practices - Annex 5 to the Convention on International Civil Aviation - Units of Measurement to be Used in Air and Ground Operations Fifth Edition - July 2010]</ref> China, Mongolia, Russia and many [[Commonwealth of Independent States|CIS]] countries have used flight levels specified in [[metre]]s for years. Aircraft entering these areas normally make a slight climb or descent to adjust for this, although Russia and some CIS countries started using feet above transition altitude and introduced RVSM at the same time on 17 November 2011.

=== Kyrgyzstan, Kazakhstan, Tajikistan, Uzbekistan, and Turkmenistan ===
The flight levels below apply to [[Kyrgyzstan]], [[Kazakhstan]], [[Tajikistan]] and [[Uzbekistan]] and 6,000 m or below in [[Turkmenistan]] (where feet is used for FL210 and above). Flight levels are read as e.g. "flight level 7,500 metres":

=== People's Republic of China and Mongolia===
The flight levels below apply to [[Mongolia]] and [[People's Republic of China]], not including Hong Kong. To distinguish flight levels in feet, flight levels are read without "flight level", e.g. "one two thousand six hundred metres" or for 12,600 m (Chinese only available in Chinese airspace). To distinguish altitude from flight level, "on standard" or "on QNH" would be added during initial clearance, such as "climb 4,800 metres on standard" or "descent 2,400 metres on QNH 1020".

RVSM was implemented in China at 16:00 UTC on 21 November 2007, and in Mongolia at 00:01 UTC on 17 November 2011. Aircraft flying in feet according to the table below will have differences between the metric readout of the onboard avionics and ATC cleared flight level; however, the differences will never be more than thirty metres.
