What is the altitude range for RVSM airspace?

The altitude range for Reduced Vertical Separation Minimum (RVSM) airspace is indeed from Flight Level 290 (FL290) to Flight Level 410 (FL410). RVSM is a regulatory framework that allows for a reduced vertical separation between aircraft flying at these altitudes, specifically lowering the standard separation from 2,000 feet to 1,000 feet. This altitude range is specifically designated to optimize airspace usage and enhance the efficiency of the air traffic control system.

At these flight levels, the RVSM ensures that aircraft can operate safely while maintaining adequate separation, thereby allowing for an increased number of flights in a given airspace. This altitude range is crucial for high-altitude flights commonly used by commercial airliners and other large aircraft, where maintaining safe separation is imperative due to the higher speeds and altitudes at which they operate.
