What does Reduced Vertical Separation Minimums (RVSM) change about vertical separation, and where is it implemented?

• A. 2000 ft between all levels globally
• B. 1500 ft above FL300
• C. 1000 ft between FL290 and FL410; implemented in high-altitude enroute facilities
• D. 500 ft between FL200 and FL600

Answer: (C)

RVSM changes vertical separation by reducing it from 2,000 ft to 1,000 ft, but only in designated high-altitude enroute airspace where aircraft are RVSM-compliant. The specific flight level band for this reduced separation is between FL290 and FL410. This tighter spacing increases capacity and efficiency of high-altitude routes, but it relies on aircraft having reliable, redundant altitude-determination and automatic altitude-keeping systems, and on established procedures to ensure both aircraft involved meet the required performance. The other options describe the wrong separation values or apply them outside the RVSM design, and they don’t reflect where RVSM is implemented.
