What is the altitude range for RVSM airspace?

The altitude range for Reduced Vertical Separation Minimum (RVSM) airspace is specifically from Flight Level (FL) 290 to FL 410. This spacing is implemented to allow aircraft to operate in closer vertical proximity, enhancing the efficiency of air traffic control and increasing the capacity of the airspace without compromising safety.

RVSM allows for a vertical separation of 1,000 feet between aircraft operating in this specific altitude range, rather than the standard 2,000 feet required at other altitudes. The airspace from FL290 to FL410 is designated for RVSM to ensure that aircraft at these altitudes can safely operate with a reduced vertical separation, accounting for the performance and precision requirements necessary to maintain safe operations within this environment.

Understanding this aviation regulation is important for flight planning and compliance with air traffic control directives. The other altitude ranges listed do not match the specific criteria set for RVSM, which is why they are not considered correct.
