Within RVSM airspace, which flight level is allowed?

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

Answer: (A)

RVSM airspace uses a reduced vertical separation of 1000 feet, but only within a defined altitude band. That band runs from Flight Level 290 up to Flight Level 410, inclusive. Within this range, aircraft can operate with RVSM minimums, increasing capacity and efficiency. The other options describe ranges outside this band or only a portion of it, which don’t define where RVSM applies. Therefore, the flight levels allowed in RVSM are between Flight Level 290 and Flight Level 410.
