What is the definition of RVSM?

The correct definition of RVSM is "Reduced Vertical Separation Minimums." This term refers to a set of procedures and standards that allow for a reduction in the vertical separation standards over certain airspace, specifically from 2,000 feet to 1,000 feet between aircraft flying at altitudes between 29,000 and 41,000 feet. This reduction enhances airspace efficiency and capacity by allowing more aircraft to operate at optimal flight levels.

The implementation of RVSM is critical for managing air traffic in busy airspace, as it promotes more efficient use of the available altitude, reducing congestion and minimizing delays. This system is supported by specific equipment and maintenance requirements for participating aircraft to ensure safe operations under the reduced separation standards. Therefore, the distinction that RVSM represents a reduction in vertical separation while maintaining safety standards is crucial in understanding its significance in aviation operations.
