Background Work Program
Background ICAO Performance Based Navigation Concept Airspace Concept Com Nav Surv ATM Nav Applications Nav Specifications Nav Infrastructure RNAV Specifications RNP Specifications RNAV10 (RNP 10) RNP 4 RNP 2 RNP 1 Advanced RNP RNP 0.3 RNP APCH RNP AR APCH RNP w/ Added Requirements e.g. 3D, 4D RNAV 5 RNAV 2 RNAV 1
Background Navigation Specifications Applications reflect performance/functional requirements ** includes optional function of RNP scalability
Volume I Vol I, Part B Major update to implementation processes based upon lessons learned and feedback from ICAO/FAA/ EUROCONTROL PBN Seminars
Volume I Operations Approval Guidance Attachment C to Vol I Objective Provide a high level summary of operational approval processes for general awareness, and complement the new operations approval manual. Rationale Operations approval identified from seminars, Go Team activities and general enquiries as one of the major hurdles for the global implementation of PBN.
Volume II Navigation Specifications Implementing RNP 2 • Chapter 2, Vol II, Part C • Objective • RNP 2 is primarily intended for a diverse set of en route applications; particularly in geographic areas with little or no ground NAVAID infrastructure, limited or no ATS surveillance, and low to medium density traffic , Oceanic/Remote and Continental applications • Rationale • This provides a solution where RNP routes can be implemented as an element of improved airspace design and traffic flow. • Issues • The higher continuity option will need to be addressed through operational approval and flight planning.
Volume II Navigation Specifications Implementing Advanced RNP • Chapter 4, Vol II, Part C • Objective • Provide for RNP operations where the RNP is applicable to all phases of flight, and with RNAV holding, parallel offset, & Radius to Fix as required and Fixed Radius Transition and RNP scalability from 0.3 to 1.0 NM, for terminal airspace, as options. • Rationale • Provides • A means for a single aircraft qualification • Improved airspace capabilities via Advanced RNP functionality • Significantly enhanced approach and departure capabilities • Issue • This provides value through it’s operational applications but is sufficiently complex that additional ICAO information and implementation guidance is strongly recommended.
Volume II Navigation Specifications Implementing RNP 0.3 Chapter 5, Vol II, Part C Objective Provide for RNP operations predicated on rotorcraft RNP systems using TSO-C145()/C146() functionality Rationale Rotorcraft RNP systems contain the capability for performing RNP operations where improved heliport access and routing through dense airspace is facilitated. Note: This may also be used for qualified fixed wing aircraft. .
Volume II Navigation Specifications Implementing RNP AR APCH • Chapter 6, Vol II, Part C • Objective • Extend RNP AR to address departure. • Rationale • Initial specification only addresses approach, omitting departure. AR operations are needed for departures from some of the very same runways where AR approach exists. • Issues • Not accomplished due to lack of a focal and time. A future action is required due to the demand for departure guidance material. • Outgrowth of discussions identified the need for guidance material concerning use of PBN for one engine inoperative.procedures e.g., at ICAO Ops Panel.
Volume II Navigation Specifications Radius To Fix (RF) Path Terminator Appendix to Vol II, Part C Objective Provide for fixed radius turns in non-RNP AR APCH applications, where operational improvements can be achieved e.g. environment, access and terrain/obstacles are not a factor. Applicable only on RNP terminal airspace procedures (SID/STAR) and on approach operations outside of the final approach segment. Rationale Provide a predictable and repeatable ground track where fixed ground tracks are required to achieved reduced separation minima, improved traffic flow, or reliable turn performance.
Volume II Navigation Specifications Fixed Radius Transition (FRT) Appendix to Vol II, Part C Objective Provide for fixed radius transitions along RNP ATS routes [for use with Advanced RNP and RNP 2] Rationale Provide a predictable and repeatable ground track where fixed ground tracks are required to achieved reduced separation minima, improved traffic flow, or reliable turn performance.
Volume II Sample Airspace Concept Based On Nav Specs Attachment B to Vol II Objective Provide examples of route spacing achieved per flight phases [with and without radar surveillance] using PBN in specific environments Rationale Following the removal of Attachment B to Annex 11, it was necessary to locate the sample route spacing in another ICAO document. It also is a response to frequent enquiries on the subject.
Conclusions • PBNSG has completed its work on the update to the PBN Manual. • It is recommended that ICAO proceed with publishing the manual. • Shortcomings with filing of PBN in the 2012 ATC FPL identified, which will need to be addressed pre-FF ICE. • Consequential changes [for routes with FRT] are required to ICAO documentation including Annex 11. • It is recommended that ICAO develop supporting guidance/information for the new navigation specifications, especially Advanced RNP. • The timeline for implementation will need to reflect development of supporting guidance material and implementation processes by States. • It is anticipated that future actions will be necessary post-PBNSG to support implementation. • The PBNSG is willing to support ICAO on PBN related papers to ANC/12.
