How does RVSM impact aircraft separation?

RVSM, or Reduced Vertical Separation Minimum, is a set of regulations that allows aircraft to operate at closer vertical intervals in the airspace above 29,000 feet mean sea level. Traditionally, aircraft were separated by 2,000 feet in altitude, but RVSM permits a reduction to 1,000 feet for aircraft that are equipped to comply with specific performance requirements.

The correct answer highlights this change by indicating that RVSM reduces the vertical separation minimum from 2,000 feet to 1,000 feet. This adjustment increases the capacity of the airspace, allowing more aircraft to operate in the same altitude strata, which is particularly beneficial in congested airspaces. Implementing RVSM requires that aircraft meet strict altitude-keeping accuracy and equipment requirements to ensure safety, as closer vertical separation necessitates enhanced precision in maintaining altitude.

Other options suggest different reductions that do not reflect the established RVSM protocols. Understanding RVSM is crucial for pilots and air traffic controllers to ensure efficient and safe management of high-altitude air traffic.
