FAA Makes Change in New York Center Oceanic Clearance Procedures

January 22, 2013

Beginning on February 5, 2013 at 1200Z, New York Center will modify the procedures that are used to issue Oceanic Clearances to eastbound aircraft entering Minimum Navigation Performance Standard (MNPS) Airspace. These procedures only apply to aircraft entering the New York Oceanic CTA from a FAA Facility. Route, altitude and speed are the three components to an Oceanic Clearance. The FAA is changing the delivery method of these three components. Beginning on February 5, 2013, the FAA will consider the airport clearance which an aircraft receives on the ground at its departure airport to be the route portion of the Oceanic Clearance. Altitude and speed assignments will occur prior to entry into the New York Center Oceanic CTA. View the notice (23 KB, PDF)
