Long-term Monitoring

Minimum Monitoring Requirements

Aircraft operators who wish to maintain RVSM approval for their aircraft/aircraft fleet are required to satisfy the standard and recommended practice of the long-term monitoring requirements, as specified in ICAO Annex 6 Part I Section 7.2.7 and Part II Section 2.5.2.7. This states that to ensure the safety of flight operations within the RVSM airspace:

“The State of Registry that has issued an RVSM approval to an owner/operator shall establish a requirement which ensures that a minimum of two aeroplanes of each aircraft type grouping of the owner/operator have their height-keeping performance monitored, at least once every two years or within intervals of 1000 flight hours per aeroplane, whichever period is longer. If an owner/operator aircraft type grouping consists of a single aeroplane, monitoring of that aeroplane shall be accomplished within the specified period.”

The number of aircraft required to be monitored is dependent upon the monitoring group and category as specified in the Minimum Monitoring Requirements.
