North American Approvals Registry and Monitoring Organization - NAARMO
Through bi-lateral agreements with Canada and Mexico, the Federal Aviation Administration 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 (ICAO) documents.
The NAARMO is located at the William J. Hughes FAA Technical Center in Atlantic City, New Jersey.
NAARMO provides services to monitor aircraft height-keeping performance and maintains a database of State RVSM Approvals. NAARMO also verifies the RVSM Approval status of operators and aircraft using North American RVSM airspace.
