CRJ maximum Mach number in RVSM airspace is which value?

• A. 0.80
• B. 0.83
• C. 0.85
• D. 0.87

Answer: (B)

In RVSM airspace, the limit is set to ensure reliable altitude-keeping and air data accuracy. Maintaining 1000 ft vertical separation relies on instruments and flight control systems performing within validated ranges. Most transport-category aircraft, including CRJs, are certified to operate up to Mach 0.83 in RVSM conditions, so this speed keeps true airspeed and pressure readings within the envelope used to certify precise altitude maintenance. Pushing beyond Mach 0.83 would require additional approvals and equipment and isn’t part of standard RVSM operations. That’s why the maximum Mach number in RVSM airspace is 0.83.
