What is the maximum cruise Mach speed for the CRJ 900 in RVSM airspace?

The maximum cruise Mach speed for the CRJ 900 in RVSM (Reduced Vertical Separation Minimum) airspace is 0.82 Mach. This limit is established to ensure safe operations and compliance with air traffic regulations, particularly concerning altitude separation between aircraft operating in RVSM airspace. The specified maximum speed helps to maintain orderly traffic flow and prevent conflicts between aircraft, which is essential for safety and efficiency in high-density airspace.

It is important for pilots to adhere to this limitation to facilitate the safe navigation of multiple aircraft flying at similar altitudes while minimizing the risk of adverse interactions. By following the maximum speed of 0.82 Mach, pilots contribute to safer and more organized airspace operations, in accordance with the standards defined for the CRJ 900.
