What is the standard vertical separation reduction implemented by RVSM?

Reduced Vertical Separation Minimum (RVSM) is a set of standards used in aviation to increase airspace capacity by allowing aircraft to operate with smaller vertical separation between them than previously required. Under the traditional separation criteria, aircraft flying in the same airspace were typically separated by 2000 feet vertically. However, with RVSM, this vertical separation has been reduced to 1000 feet, significantly increasing the efficiency of air traffic management.

This reduction allows for more aircraft to occupy the same airspace while maintaining safety, as modern aircraft are equipped with advanced altimetry systems capable of maintaining accurate altitude. The implementation of RVSM has been crucial in optimizing flight operations and enhancing the overall capacity of controlled airspace, particularly in busy aviation corridors.
