Dear Mr/Ms, MONITORING OF NORTH ATLANTIC (NAT) - APPROVALS FOR OPERATING IN MINIMUM NAVIGATION PERFORMANCE SPECIFICATIONS AIRSPACE 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. The procedure adopted by ............... Oceanic Area Control Centre is that when a pilot requests a NAT oceanic clearance that includes MNPS levels the pilot maybe asked to confirm the MNPS approval status. In the situation where a pilot is unable to give this confirmation the details are passed to this office, which acts as the Central Monitoring Agency (CMA) for NAT SPG, in order that the State of Registry or the State of the Operator involved maybe notified. It was noted that the pilots of the following flight/s/list of flights, which took place on ........, and for which we believe you to be the State of Registry/the Operator, was/were unable to give assurance that he/they, possessed NAT MNPS approval. We would be grateful if you would investigate the circumstances, and advise whether or not this/these flights was/were in possession of a formal State Approval for NAT MNPS Operations. If the flights was/were 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
