What is the primary purpose of reduced vertical separation minimums (RVSM)?

The primary purpose of reduced vertical separation minimums (RVSM) is to increase air traffic management efficiency. RVSM allows aircraft to operate at altitudes with less vertical separation than was previously required, effectively creating more available flight levels within the same airspace. This change enables air traffic controllers to manage a higher number of flights safely and efficiently, especially in busy airspace regions, thereby optimizing airspace utilization.

While aspects such as lower operational costs, enhanced navigational accuracy, and improved flight safety are important considerations in aviation, they are secondary benefits that arise from the implementation of RVSM. The main goal focuses on maximizing air traffic capacity and management effectiveness, ensuring a higher volume of aircraft can be accommodated without compromising safety standards.
