What is one of the required operational components for RVSM?

For Reduced Vertical Separation Minimums (RVSM) operations, having an operational autopilot is essential. The reason it is a requirement is that RVSM regulations allow aircraft to operate with reduced vertical separation between them, typically 1,000 feet instead of the standard 2,000 feet. To maintain safe and precise altitude control within this reduced vertical space, the autopilot system plays a crucial role in ensuring that the aircraft can hold its assigned altitude with high reliability and accuracy.

If the autopilot is inoperative, the likelihood of altitude deviations increases, which could compromise the safety of the operation in an RVSM airspace. Therefore, it is not just a matter of convenience but a critical safety operational component mandated by regulatory authorities for the management of flight altitudes in RVSM airspace.
