Through bi-lateral agreements with Canada and Mexico, the FAA has established the North American Approvals Registry and Monitoring Organization (NAARMO) as the official regional monitoring agency supporting implementation and continued safe use of the North American Reduced Vertical Separation Minimum (RVSM). Operation of a Regional Monitoring Agency is called for in pertinent International Civil Aviation Organization documents. The NAARMO resides at the FAA Technical Center in Atlantic City, New Jersey.
The functions of the NAARMO include:
Systems to monitor aircraft height-keeping performance Establishment and maintenance of a database of State RVSM approvals Scrutiny of the RVSM approval status of operators and aircraft using North American RVSM airspace.
