RVSM stands for Reduced Vertical Separation Minimum. What does this exactly mean? In more detail, RVSM is used to reduce the vertical separation of an aircraft from 2,000 feet to 1,000 feet when flying at altitudes between 29,000 feet (FL240) and 41,000 feet (FL410).
RVSM is use today because it significantly increases the number of airplanes that can fly in a defined airspace area. In theory, RVSM nearly doubles the number of airplanes per area. It also allows pilots to choose more efficient altitudes and avoid unwanted turbulence. Watch the brief video below to learn more.
