Official Publication of Area Navigation (RNAV) Y- Routes inAtlantic High Offshore Airspace Beginning May 26, 2016

Introduction: RNAV routes, located predominantly within Atlantic High Offshore Airspace and generallybetween Florida and Puerto Rico, will be published in U.S. government aeronautical en route chartsbeginning May 26, 2016. The routes, identified as Y585, Y586, Y587, Y588 and Y589, have been inexistence since 1999 but published only in commercially prepared charts and available for use only by thoseoperators meeting special requirements. The waypoints defining the routes have been listed in the NationalFlight Data Digest since route inception. Publication of the Y-routes in U.S. government charts makes theroutes available to all operators.

General Requirements and Eligibility: Effective with their publication on May 26, 2016, the Y-routes shallbe considered RNAV 2 with GNSS required. RNAV systems relying solely on DME/DME or inertialnavigation are not suitable for and therefore not authorized for use on the Y-routes. For additional informationplease consult section ENR 7.10, Y-Routes Between Florida and Puerto Rico, Aeronautical InformationPublication (AIP), United States of America.

Strategic lateral offset procedures (SLOP), defined in ICAO Doc 4444 Procedures for Air NavigationServices – Air Traffic Management section 16.5, are not to be applied while flying the Y-routes.

AC 90-100 U.S. Terminal and En Route Area Navigation (RNAV) Operations contains pilot knowledgesubject matter that is applicable to all RNAV operations. All pilots intending operations on the Y-routesshould consider the RNAV subject matter contained in AC 90-100 when assessing their qualification andreadiness to fly those routes.(Performance Based Flight Systems Branch, AVS−470 3/03/16)
