Operating Procedures and Training Q Q Q Pre-flight planning In-flight procedures Performance expectations (deviation from path) Ø Pilot has critical role in performance monitoring Q Contingency procedures Q Training Ø Lists training tasks considered important, which may already be part of operator’s training program Ø System-specific information on how navigation system functions is vital to success Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 11

Navigation Service Provider Responsibilities Q Navigation infrastructure Ø DME geometry with respect to route Q Communication and surveillance Ø Radar required or not? Q Obstacle clearance and route spacing; Publication Q Controller Ø Not meant to impose new requirements Q Status monitoring Q ATS System monitoring Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 12

Conclusion Q Navigation Specification provides implementation guidance for PBN operations Q Focus of navigation specification is on aircraft and operator Ø Other aspects covered in appropriate ICAO document (for example, PANS-OPS) Q New Navigation Specifications will be developed as appropriate Ø For example, Advanced RNP-1 Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 13
