At what altitudes does RVSM begin and end?

The correct answer indicates that Reduced Vertical Separation Minimum (RVSM) airspace starts at Flight Level 290 (FL290) and extends up to Flight Level 410 (FL410). This altitude range allows a decrease in vertical separation between aircraft from the standard 2,000 feet to 1,000 feet, which is crucial for enhancing airspace capacity and efficiency, especially at higher altitudes where traffic congestion can occur.

The specific altitudes for RVSM were determined to balance safety with efficiency in the busy airspace above 29,000 feet, where more precise altitude maintenance and modern aircraft capabilities can be utilized. Operators must have RVSM approval and meet specific equipment and operational requirements to operate within this airspace, underlining the importance of these regulations for maintaining safety and improving the flow of air traffic.

Understanding RVSM's altitude range is vital for pilots and operators involved in Part 135 operations, ensuring their awareness of air traffic management protocols and compliance with regulatory requirements in their operational environment.
