This circular provides guidelines and supporting material for the implementation of performance-based navigation (PBN) departure procedures with reduced divergence intended for use with aircraft flying area navigation (RNA V) departure procedures whose courses diverge immediately after departure. The material in this circular modifies provisions previously included in Chapter 6 of the Procedures for Air Navigation Services - Air Traffic Management (PANS-ATM, Doc 4444, Chapter 6 of the Procedures for Air Navigation Services - Aircraft Operations (PANS-OPS, Doc 8168) and Chapter 3 of the Manual on Simultaneous Operations on Parallel or Near-Parallel Instrument Runways (SOIR, Doc 9643). The material in this circular is limited to the application of minimum divergence angles of RNA V 1 instrument flight procedures used in an air traffic services (ATS) surveillance environment by aircraft that depart from paral1el runways with minimum centerline spacing of760 m (2 500 feet).
