Domestic Reduced Vertical Separation Minimum (DRVSM) Explained
Posted by Jeffrey on 23rd February 2009
Introduction to DRVSM
Domestic Reduced Vertical Separation Minimum (DRVSM), also designated as RVSM, is a new altitude structure program in the U.S. that has been in use in numerous regions of the world and in designated flight tracks across the Atlantic Ocean since 1977.
It has been designed around the principals of:
- Extending the usable airspace at and above FL290 (29,000 feet MSL) to FL410 to enhance ATC flexibility with traffic flow
- Helping alleviate crossing traffic and conflict points in high density airspace
Increasing airspace capacity - Providing enhanced operating efficiencies of flying at more fuel efficient flight levels and user preferred routing
- Reducing ATC controller work load
DRVSM is currently the designation of RVSM airspace and operations within the United States. The designation DVRSM is synonymous with RVSM and it currently identifies all intended Reduced Vertical Separation Minimum (RVSM) airspace operations and is designated as the airspace beginning at FL290 and extending up to and including FL410.
