What does RVSM stand for?

RVSM stands for Reduced Vertical Separation Minima. This term refers to a set of regulations that allow aircraft flying at cruising altitudes to be separated vertically by a minimum of 1,000 feet, instead of the traditional 2,000 feet. This reduction in vertical separation is crucial for improving airspace capacity and efficiency, particularly in congested air traffic regions. The implementation of RVSM has allowed more aircraft to safely occupy the same airspace without compromising safety standards, ultimately enhancing the overall performance of national and international airspace systems.

The other choices do not accurately reflect the established terminology or the principles behind air traffic management. Familiarity with RVSM is important for anyone involved in aviation, as it plays a vital role in modern air navigation and safety management.
