The Pelesys PBN Operations course has been developed in response to significant changes in Performance Based Navigation which resulted from the publication of ICAO PBN Manual Revision 004 (Doc 9613). The material covers PBN concepts, and details the framework for the application of the RNAV and RNP Navigation Specifications to Airspace Concepts, operational requirements including Onboard Performance Monitoring and Receiver Autonomous Integrity Monitor with and without onboard Fault Detection and Exclusion, and contingency operations in Performance Airspace. The course also details the application of PBN to Terminal, Approach and Missed Approach Operations, including RNP Approach and RNP Approval Required applications.
