How does RVSM (Reduced Vertical Separation Minima) impact ATC operations?

• A. It eliminates vertical separation requirements.
• B. It allows reduced vertical separation between flight levels (e.g., FL290–FL410) increasing capacity; ATC must verify aircraft are RVSM-equipped and maintain level monitoring.
• C. It increases horizontal separation.
• D. It requires aircraft to fly at fixed levels with no changes.

Answer: (B)

RVSM reduces the vertical separation between aircraft within the designated RVSM airspace, typically allowing 1,000 ft between adjacent flight levels in the FL290–FL410 range. This tighter spacing increases capacity because more flight levels and more aircraft can occupy the same vertical space without compromising safety. To enable this, ATC must verify that each aircraft operating in RVSM airspace is RVSM‑equipped and certified, and continuously monitor altitude-keeping performance to ensure the aircraft remain within required tolerances. Outside RVSM airspace, standard vertical separation applies, and the reduced spacing does not apply. The other options aren’t correct because RVSM does not eliminate vertical separation, it does not inherently change horizontal separation, and it does not require flying at fixed levels with no changes.
