## Abstract

This final rule amends the airspace where Reduced Vertical Separation Minimum (RVSM) may be applied to include Pacific oceanic airspace. RVSM is the reduction of the vertical separation of aircraft from 2,000 feet to 1,000 feet at flight levels (FLs) between FL 290 (29,000 feet) and FL 410 (41,000 feet). RVSM is applied only between aircraft that meet stringent altimeter and autopilot performance requirements. RVSM is currently applied only in North Atlantic (NAT) Minimum Navigation Performance Specifications (MNPS) airspace. The introduction of RVSM in Pacific oceanic airspace will make more fuel and time efficient flight levels and tracks available to operators. RVSM will also enhance airspace capacity in the Pacific. In North Atlantic airspace, RVSM has been shown to maintain in acceptable level of safety since March 1997.
