In RVSM airspace, what vertical separation is required between aircraft?

• A. 2000 feet
• B. 1500 feet
• C. 500 feet
• D. 1000 feet

Answer: (D)

RVSM airspace uses a vertical separation of 1000 feet between aircraft, within the defined RVSM flight level band and only when both aircraft are equipped and maintained to required altitude-keeping standards. This tighter separation is made possible by precise altitude maintenance and reliable altitude monitoring, which together ensure safe spacing even with higher traffic density. The other numbers listed aren’t used in RVSM because outside this reduced-separation regime the standard separation is larger.
