ICAO CIRCULAR 353 PDF

Purpose

The purpose of this circular is to provide guidance on the transition from the area navigation (RNAV) global navigation satellite system (GNSS) RWY XX approach naming convention to RNP RWY XX, in accordance with Amendment 6 to the Procedures for Air Navigation Services — Aircraft Operations (Doc 8168, PANS-OPS), Volume II — Construction of Visual and Instrument Flight Procedures. In particular, this circular provides the framework for a global transition plan, the framework for developing a regional transition plan by the ICAO regional offices, and provides guidance to the States on how to develop a transition plan. In each case, all stakeholder requirements need to be considered, as well as hazards, risks and mitigations of transition planning and implementation.

A global timeline for conversion is established. Within this global time frame, each region inherits its own period of transition, and each State receives—from its regional transition plan—a dedicated time slot during which the region will transition to the new chart identifications. Each State should plan to complete the transition in accordance with this slot. No regional transition plan should extend beyond the target date of the global timeline.
