In 1997 the FAA issued a 最后的规则 establishing requirements for operations of U.S.-registered aircraft in airspace designated as Reduced Vertical Separation Minimum (RVSM) airspace. RVSM refers to airspace between flight level (FL) 290 and FL 410, 高度之间至少相隔1,000英尺而不是2,000-foot minimum separation currently required above FL290. The regulations ensure that 运营商 and their aircraft are properly qualified and equipped to conduct flight operations while separated by 1,000英尺, and ensure that compliance with the RVSM requirements is maintained. This amendment makes more tracks and altitudes available for air traffic control to assign to 运营商, thus increasing efficiency of operations and air traffic capacity.

For detailed information on the implementation of RVSM in US airspace – or Domestic RVSM (DRVSM) – review the following references:

NBAA Part 91 RVSM Operational and 维护 Templates

更新10月. 20, 2011

Updated Part 91 operational and maintenance templates have been issued to assist 运营商 in developing an RVSM manual for FAA approval and Letter of Operational Authorization (LOA).

The templates are based upon FAA Airworthiness 安全 Inspectors’ evaluation instructions. They provide a starting point to operational and maintenance approval, but should not be considered an FAA-approved document.

这些模板符合要求 手册8300.10、变更16卷. 2、第五章(2mb, PDF),增强了AC 91.706,附录G和91-RVSM临时指南.

When finalizing and submitting an RVSM manual for FAA approval, 运营商 must: tailor the manual for their operation, 充分理解手册内容, and maintain the manual in conjunction with airworthiness compliance regulations. 一旦获得批准, the operator must note “accomplished in accordance with Operators Approved RVSM Manual” on an aircraft’s return to service following any maintenance event or inspection.

联邦航空局发布了 建议制定规则的补充通知 2月. 28, 2003, regarding implementation of Domestic Reduced Vertical Separation Minimum (DRVSM). The Agency is adding a proposal to implement RVSM between flight levels 290 and 410 in Atlantic High and Gulf of Mexico High Offshore airspace and in the San Juan Flight Information Region. The FAA also intends to remove the proposed option that would have permitted Part 91 turbo-propeller aircraft to operate in DRVSM airspace with a single RVSM-compliant altimeter.

10月. 2003年27日,美国联邦航空局发布 最后的规则 在美国的RVSM上.S. 国内空域. Final规则允许使用1,000-foot vertical separation at certain altitudes between aircraft that meet stringent altimeter and autopilot performance requirements. The rule also requires any aircraft that is equipped with Traffic Alert and Collision Avoidance System version II (TCAS II) and flown in RVSM airspace to incorporate a version of TCAS II software that is compatible with RVSM operations, stating that if you operate an aircraft that is equipped with TCAS II in RVSM airspace, “it must be a TCAS II that meets TSO C–119b (Version 7.0),或更高版本.” It should be noted that there is no requirement to install TCAS to operate in RVSM airspace.
