What levels does RVSM apply to?

RVSM, or Reduced Vertical Separation Minimum, applies to aircraft operating in the airspace between Flight Level 290 (FL290) and Flight Level 410 (FL410). This regulatory framework allows aircraft to fly at altitudes much closer together, specifically only 1,000 feet apart instead of the traditional 2,000 feet that is typically used at lower altitudes.

The introduction of RVSM helps to optimize the use of available airspace, enhances traffic flow, and increases airspace capacity by allowing for more aircraft to safely navigate at higher altitudes.

This altitude range addresses the needs of both commercial and general aviation, ensuring that aircraft can maximize their operational efficiency while maintaining safety standards in controlled airspace. The other altitude options mentioned do not align with the specific airspace being regulated by RVSM, which is strictly defined as between FL290 and FL410.
