Reduced Vertical Separation Minimum - RVSM...read more about it! The goal of RVSM is to reduce the vertical separation above flight level (FL) 290 from the current 2000-ft minimum to 1000-ft minimum. This will allow aircraft to safely fly more optimum profiles, gain fuel savings and increase airspace capacity. The process of safely changing this separation standard requires a study to assess the actual performance of airspace users under the current separation (2000-ft) and potential performance under the new standard (1000-ft). In 1988, the ICAO Review of General Concept of Separation Panel (RGCSP) completed this study and concluded that
safe implementation of the 1000-ft separation standard was technically feasible
United States Domestic RVSM (DRVSM) DRVSM Program Overview - The U.S. Domestic RVSM Program is a key element of the FAA’s National Airspace System Operational Evolution Plan (NAS OEP). Please visit the OEP web site for additional information.
- On January 20, 2005, RVSM was implemented between flight level (FL) 290-410 (inclusive) in the airspace of the lower 48 States of the United States, Alaska, Gulf of Mexico and Atlantic High Offshore Airspace (including Houston and Miami Oceanic airspace) and the San Juan FIR.
- RVSM was implemented on the same date and at the same flight levels in Canadian Southern Domestic Airspace and in Mexico. (RVSM was implemented in Canadian Northern Domestic Airspace in April 2002).
- The RVSM program enables vertical separation to be reduced between FL 290-410 (inclusive) from 2,000 ft. to 1,000 ft. RVSM was first implemented in North Atlantic Airspace in 1997. It is now implemented in other major airspaces such as Europe, the Pacific Ocean and Australia.
- DRVSM provides user and provider benefits in domestic U.S. operations that have been enjoyed since 1997 in other world airspaces. RVSM makes six additional flight levels available for operations between FL 290-410. It enhances aircraft operating efficiency by making more fuel/time efficient flight levels available; enhances air traffic control flexibility and provides the potential for enhanced enroute airspace capacity.
