The ICAO Separation and Airspace Safety Panel (SASP) identified that height-keeping performance monitoring results for RVSM approved aircraft had, in some cases, demonstrated long-term adverse trends in altimetry system error (ASE) stability. The likely results of this trend, if not reversed, would be aircraft becoming non-compliant with RVSM requirements.

To ensure that adverse trends in ASE stability are detected, globally applicable RVSM long-term height monitoring requirements have been implemented. ICAO Annex 6 - Operation of Aircraft that detail global RVSM long-term monitoring requirements that became effective on 18 November 2010. These requirements are: 7.2.7 The State of the Operator that has issued an RVSM approval to an operator shall establish a requirement which ensures that two aeroplanes of each aircraft type grouping of the operator have their height keeping performance monitored, at least once every two years or within intervals of 1,000 flight hours per aeroplane, whichever period is longer. If an operator aircraft type grouping consists of a single aeroplane, monitoring of that aeroplane shall be accomplished within the specified period.

RVSM Minimum Monitoring Requirements (MMRs) have been adopted for global application by all ICAO Regional Monitoring Agencies (RMAs) and are the basis for implementation of the Annex 6 requirements. The MMR are located in:

AAMA maintains a database of all relevant RVSM-approved aircraft, containing information on the monitoring status of each aircraft.

The PDFs below present relevant information from this database to assist operators in managing their height-monitoring requirements. RVSM-approved aircraft, as notified by the relevant regulator, are listed alphabetically by operator and registration. The 'Last monitored' date is established in accordance with MMR requirements and based on ADS-B monitoring conducted by Airservices Australia, or as advised by other Regional Monitoring Agencies.
To assist operators with planning, a 'Monitoring due' date is calculated as two years from the last successful monitoring. Aircraft that are not successfully monitored by this date are flagged as not satisfying monitoring requirements.
