What vertical separation is provided in RVSM airspace?

In Reduced Vertical Separation Minimum (RVSM) airspace, there is a vertical separation of 1,000 feet between aircraft operating at altitudes between 29,000 feet and 41,000 feet. This regulation allows for more efficient use of the airspace, increasing air traffic capacity while maintaining safety. The implementation of RVSM was made possible due to advancements in navigation technology and increased accuracy in altitude measurement, allowing aircraft to safely operate with a reduced vertical separation compared to the standard 2,000 feet used outside RVSM airspace. This improved separation helps aircraft to utilize the available altitude blocks more effectively, accommodating a greater number of flights at high altitudes.
