MONITORING OF NORTH ATLANTIC (NAT) - APPROVALS FOR OPERATING IN MINIMUM NAVIGATION PERFORMANCE SPECIFICATION AIRSPACE (MNPSA) AT RVSM LEVELS At its 25th meeting, the ICAO North Atlantic Systems Planning Group (NAT SPG) concluded that NAT Provider States should introduce, where possible, procedures designed to monitor the approval status of Operators in NAT MNPS Airspace, in order to assist in reducing the number of non-approved users. At its 32nd meeting, the NAT SPG extended these procedures to include the monitoring of Operator approvals to operate at RVSM levels within the aforementioned airspace. It was noted that the pilot of flight, a type, registration, which flew from departure airfield) to (destination airfield) on (date, and for which we believe you to be the State of Registry, gave assurance that he/she possessed the required approval. We have no record of this approval on the RVSM Approvals database and would be grateful if you would investigate the circumstances, and advise whether or not this flight was in possession of formal State Approval for NAT MNPS operations at RVSM levels. If the flight was not so approved we would be grateful if you would further notify this office of your proposed course of action. Yours faithfully, Signature) NAT CMA for ICAO
