ECAC States AIP en-route publication issues Required update The Document distributed on 30 th August 2013 stated that all observations were referenced to the ERNIP and to Annex 15, Amendment 36 in force from 18 NOV 2010. The new Annex 15, Amendment 37 was adopted by the ICAO Council at the sixth meeting of its 198 th Session on 1 March 2013. In addition, the Council resolved that Amendment 37, to the extent it becomes effective, will become applicable on 14 NOV 2013. The amendments in Appendix 1. Contents of Aeronautical Information Publication (AIP) related to ENR 3 and ENR 4 sub-sections are publication of: the navigation accuracy requirement for each PBN (RNAV or RNP) route segment (ENR 3.1-3.4); remarks, including supplementary definition of positions where required (ENR 4.4). In ENR 3.3 the detailed description of area navigation (RNAV) routes point 2) requirement is now in respect of waypoints defining an area navigation route and not only VOR/DME RNAV route. The amendments above shall be properly incorporated in the Document and other new tasks, additional to those is Annex 2, and might be added to the States as identified airspace AIP inconsistencies. 17/03/2014
Area Navigation (RNAV) routes publication
ENR 3.3. Area Navigation (RNAV) routes Annex 15, Appendix 1, Amendment 37 (Nov 2013) Detailed description of area navigation (RNAV) routes, including: 1) route designator, designation of the navigation specification(s) applicable to a specified segment(s), names, coded designators or name-codes and the geographical coordinates in degrees, minutes and seconds of all significant points defining the route including compulsory or on-request reporting points; 2) in respect of waypoints defining an area navigation route, additionally as applicable: a) station identification of the reference VOR/DME; b) bearing to the nearest degree and the distance to the nearest tenth of a kilometre or tenth of a nautical mile from the reference VOR/DME, if the waypoint is not collocated with it; and c) elevation of the transmitting antenna of DME to the nearest 30 m (100 ft); 3) geodesic distance to the nearest tenth of a kilometre or tenth of a nautical mile between defined end-points and distance between each successive designated significant point; 4) upper and lower limits and airspace classification; 5) direction of cruising levels; and RNAV routes Aeronautical Data Requirements 6) the navigation accuracy requirement for each PBN (RNAV or RNP) route segment; and 7) remarks, including an indication of the controlling unit, its operating channel and, if applicable, its logon address, and any navigation specification(s) limitations. Note.- In relation to Annex 11, Appendix 1, and for flight planning purposes, defined navigation specification is not considered to be an integral part of the route designator.
RNAV routes Adapted Publication Requirement - Doc 8126, Specimen AIP
RNAV routes Summary of publication issues identified The ICAO Assembly urges all States to implement RNAV and RNP air traffic services (ATS) routes and approach procedures in accordance with the ICAO PBN concept laid down in the Performance-Based Navigation (PBN) Manual (Doc 9613). RNAV routes publication shall be done in State AIP in ENR 3.3. The main difference compare to ENR 3.1 and ENR 3.2 is the required aeronautical data for provision of area navigation on relevant route segments described in Appendix 1 Contents in AIP points 2) and 3). Currently only 5 States (one more from previous report) published RNAV routes in accordance with Annex 15 requirements. The remaining States publish the RNAV routes in either ENR 3.1 or ENR 3.2 or ENR 3.3 divided into lower and upper but using the same table formats. The aeronautical data presented is not as required by Annex 15 for definition of RNAV route. ICAO requirement is far to be a physical placement or move of aeronautical data from ENR 3.1 / 3.2 to ENR 3.3 and vice-versa. It is a requirement for publication of fundamentally different aeronautical data in order to allow RNAV operations. It is difficult to believe that the required aeronautical data in ENR 3.1 / 3.2 is sufficient to support RNAV operations with simply allowing them on these routes. Harmonized publication for all RNAV routes and publication location (AIP placeholder) in ENR 3.3 is required. All ECAC States shall adapt the aeronautical data for RNAV routes in accordance with Annex 15.
RNAV routes Publication by Lithuania - 6 MAR 2014 Resolved AIP issues: 1. Withdrawal in publication of minimum flight altitude reference. 2. Publication of required aeronautical data to describe appropriate RNAV routes. 3. Publication of navigation specification(s) applicable to a RNAV specified route. It is published as and shall further be changed to RNAV 5. 4. Publication of coordinates of some 5LNCs in degrees, minutes and seconds. Remaining AIP issues: 1. Replacement of term FL series with Direction of cruising levels (CAT I). 2. Replacement of term Dist with Geodesic DIST (CAT I). 3. Replacement of navigation specification(s) applicable to a RNAV specified route with RNAV 5 (CAT I). 4. Publication of boundary name-code designators outside of brackets and insertion there the term FIR BDRY - example LAVAR (FIR BDRY) (CAT I). 5. Publication of airspace classification at required place with lower/upper limits (CAT II). 6. Publication of all remarks placed in route designator field at appropriate column (CAT I or CAT II). ❸ ❹ ❸ ❻ ❷ ❷ ❷ ❶ ❶ ❸ ❺ ❹ 17/03/2014
RNAV routes Publication by Austria - 3 APR 2014 Resolved AIP issues: 1. Template for RNAV routes publication completely changed and adapted to Annex 15 requirements. Remaining AIP issues: 1. Publication of navigation specification(s) applicable to a RNAV specified route - RNAV 5. 2. Publication of airspace classification at required place with lower/upper limits (CAT II). 3. Publication of coordinates of some 5LNCs in degrees, minutes and seconds. 4. No aeronautical data meaning most probably VOR/DME not used as source for area navigation in accordance with Doc 9613. Require further confirmation for RNAV application within Wien FIR. ❶ ❸ ❶ ❹ ❷ 17/03/2014

Navigation Specification Publication requirements Annex 15, Appendix 1, Amendment 37 (Nov 2013) Detailed description of lower ATS routes or upper ATS routes or area navigation (RNAV) routes, including: 1) route designator, designation of the navigation specification(s) applicable to a specified segment(s), names, coded designators or name-codes and the geographical coordinates in degrees, minutes and seconds of all significant points defining the route including compulsory or on-request reporting points; Doc 9613, Volume II, Part B, Chapter 2, 2.2 IMPLEMENTATION CONSIDERATIONS 2.2.5 Publication 2.2.5.1 The AIP should clearly indicate the navigation application is RNAV 5. The requirement for the carriage of RNAV 5 equipment in specific airspace or on identified routes should be published in the AIP. The route should rely on normal descent profiles and identify minimum segment altitude requirements. The navigation data published in the State AIP for the routes and supporting NAVAIDs must meet the requirements of Annex 15 - Aeronautical Information Services. All routes must be based upon WGS-84 coordinates.
Navigation Specification Summary of publication issues identified The different use of the two kinds of PBN navigation specification RNP and RNAV should be further clarified based on provisions of Doc 7030 and Doc 9613. One navigation specification (RNAV) does not include the requirement for on-board performance monitoring and alerting while the other (RNP) includes. Currently majority of States describe the navigation specification of their area navigation routes as while only 11 States as RNAV 5 (4 more from previous report). Two States published B-RNAV while for 6 States there is no description in ENR sub-section (together with route designator) and sometimes reference to GEN 1.5 is made. The table in next slide represents the AIP publication of RNAV routes Navigation Specification as expressed by each ECAC State in publication tables. Harmonized publication of RNAV routes navigation specification and use of unique term/abbreviation - RNAV 5 (as per Doc 7030) is required. The PBN introduction should also be considered as part of this harmonization.

All routes must be based upon WGS-84 coordinates.
Carriage of RNAV 5 equipment Summary of publication issues identified The requirement for the carriage of RNAV 5 equipment in specific airspace or on identified routes published in the AIP is different from State to State AIP. In most of the States there is a defined FL above which the carriage of equipment is mandatory but this FL is different in entire ECAC airspace - FL095, FL110, FL115, FL125, FL145, FL195, FL245 etc. There are also definitions as controlled airspace, below FL115 on RNAVdefined routes, on ATS routes, on all ATS routes, State airspace, on all ATS routes under IFR and routes in lower airspace specifically classified as RNAV, on RNAV routes, en-route portion of the ATS route structure or there is no defined FL. Harmonized AIP publication of RNAV 5 application should be further considered.
