Aircraft height-keeping performance monitoring is a quality check on the engineering work and approval process associated with the safety of RVSM operations.

Yes, all operators are required to participate in the regional monitoring program. This participation usually means an operator will need to monitor individual aircraft of each type that they operate based on the Minimum Monitoring Requirement time table (ICAO/RMA MMR table).

Monitoring can take place any time after the engineering upgrade work for RVSM compliance is completed. At this point, the aircraft will be airworthiness approved for RVSM.

Aircraft can be monitored for RVSM by scheduling a GPS-based monitoring system flight or flying over a ground based monitoring system.
