CS ACNS.E.RVSM.005 RVSM system ED Decision 2013/031/R (See [AMC1 ACNS.E.RVSM.005](#_DxCrossRefBm573002866)) The RVSM system includes: (a) two independent altitude measurement systems. Each system is composed of the following elements: (1) Cross-coupled static source/system, with ice protection if located in areas subject to ice accretion; (2) Equipment for measuring static pressure sensed by the static source, converting it to pressure altitude; (3) Equipment for providing a digitally encoded signal corresponding to the displayed pressure altitude, for automatic altitude reporting purposes; (4) Static source error correction (SSEC), as required to meet the performance criteria as specified in [CS ACNS.E.RVSM.035](#_DxCrossRefBm573002865); and (5) Signals referenced to a pilot selected altitude for automatic control and alerting derived from one altitude measurement system. (b) an altitude alerting system; (c) an automatic altitude control system; and (d) a secondary surveillance radar (SSR) transponder with altitude reporting system that can be connected to the altitude measurement system in use for altitude keeping.
