RVSM reduces vertical separation between which flight levels?

RVSM reduces vertical separation between which flight levels?

• A. Between Ground Level and Flight Level 100
• B. Between Flight Levels 180 and 260
• C. Between Flight Levels 320 and 360
• D. Between Flight Levels 290 and 410

Answer: (D)

RVSM stands for Reduced Vertical Separation Minima, and it allows aircraft to be spaced vertically by only 1,000 feet in approved high-altitude airspace to increase capacity and efficiency. The specific band where this reduced separation applies is between flight level 290 and flight level 410. Within this range, air traffic control can maintain 1,000-foot vertical separation, whereas outside it, standard separation of 2,000 feet remains in effect. For aircraft to operate in RVSM airspace, they must have approved altitude-keeping equipment, two independent altitude measurement systems, and continuous altitude reporting capabilities to ensure precise and verifiable altitudes. The other ranges either fall outside the RVSM band or represent only a portion of it, so they don’t describe where the reduced separation is applied.
