At what altitude range is RVSM applicable?

RVSM, or Reduced Vertical Separation Minimum, is applicable in the altitude range from Flight Level (FL) 290 to FL 410. This particular range is significant because it allows aircraft to operate with a reduced vertical separation of 1,000 feet between flight levels, rather than the standard 2,000 feet used at lower altitudes. This increased traffic capacity is essential for optimizing the use of airspace, especially in busy air traffic regions.

The implementation of RVSM contributes to the efficient management of air traffic, as it allows for more aircraft to occupy the same airspace with reduced separation, thereby increasing the availability of altitude options for pilots, enhancing fuel efficiency, and improving overall flight safety. The designation of FL 290 to FL 410 is specifically regulated due to the operational requirements and equipment standards that aircraft must meet to operate in this environment, including altitude-keeping performance.

In contrast, the other altitude ranges do not align with the parameters established for RVSM, as they either fall outside the range or do not reflect the standards that allow for reduced separation.
