  1. Performance-based Operations Aviation Rulemaking Committee (PARC) Communications Working Group (CWG) Presented to: IPACG/39 FIT/26 By: Koji Nakaitaninakaitani-k48da@mlit.go.jpTom Krafttom.kraft@faa.gov Date: 3-7 February 2014

  2. PARC and CWG • Feb 2004 – Performance-Based Operations Aviation Rulemaking Committee (PARC) • Chartered under FAA Administrator’s authority • Formerly FAA Order 1110.139  Updated June 2010 as internal document • Focus on implementation and operational guidance • Includes PBN and PBCS • Provides industry recommendations to FAA • Considers global harmonization and standardization • Jan 2005 – Communications Working Group (CWG) established under PARC

  3. PARC CWG Process and Results • Works from Project Plans to • Evaluate communication technologies that are foreseen to be viable in meeting the needs of the aviation community • Provide executive summaries on the project (who, what, when, where, why and how) • End product – Recommendation Reports to FAA • Coordinates with ICAO and regions/other States to ensure global harmonization  embraces GOLD and SVGM • PARC CWG has been effective in applying communication technologies to meet needs of aviation community

  4. PARC CWG Members and Affiliates • 238 members/affiliates from 65 different organizations • Approximately 40 attend 2-3 meetings per year

  5. Completed Projects • Jul 2006 – Roadmap for data link • Sep 2007 – DRAFT Roadmap for Performance-based Communications • Sep 2012 – FANS 1/A over Iridium (FOI) and Performance-Based Communication and Surveillance (PBCS) Recommendations • Mar 2011 – FANS 1/A over High Frequency Data Link (FOH) Recommendations • Sep 2012 - FANS 1/A over Inmarsat-4 Classic Aero (FOICA) Recommendations

  6. Related ICAO Headquarters Activity

  7. Related ICAO Regional Activity • Asia-Pacific - provisioning for En Route Monitoring Agency (EMA) • Support horizontal separations predicated on data-link • Monitor data link approvals • Monitor actual performance against RCP/RSP • North Atlantic – provisioning for 30 NM lateral, 30 NM, 50 NM and 5-minute longitudinal • FANS 1/A data link mandate • PBCS implementation

  8. PARC CWG Current Activities • PBCS implementation • Satellite voice (SATVOICE) for ATS communications project • FANS 1/A over SwiftBroadband (SBB) safety services project • FAA NextGen domestic data link • FAA data link recording rules

  9. PBCS – Operational Authorization • State prescribes RCP and RSP • PBCS provisions for Annex 6 and Annex 11 (adapted from existing provisions for RVSM) • Operational authorization • Regional/ANSP post-implementation monitoring and operator participation • Operational authorization • Demonstrate acceptable RCP / RSP for each aircraft type in the fleet • If substandard performance, State of the Operator or State of Registry would issue corrective action notice (taking into account the severity of the deficiency and magnitude of the change) • Corrective action notice could result in restrictions on use of data link • PBCS would allow the operator to still use CPDLC and ADS-C • Operators file capability in flight plan, e.g. P2 (RCP240) in Item 10

  10. PBCS – FANS 1/A over VHF • Evaluations on FANS 1/A over very high frequency (VHF) performance • Aircraft communications addressing and reporting system (ACARS) • VHF data link (VDL) Mode 0/A – Plain old ACARS (POA) • VDL Mode 2 – ACARS over aviation VHF link control (AVLC) (AOA) • FAA advocates VDL Mode 2, however it is accepting use of VDL Mode 0/A in U.S. domestic airspace, at least initially Boeing and FAA provided report at PARC CWG

  11. PBCS – FOICA and FOI • FOICA (Inmarsat) and FOI (Iridium) • Some common issues typical of FANS 1/A operations • CMU / MU Media-ground station switching algorithms(e.g. VHF-SATCOM, satellite to satellite) • Multiple ADS contracts with aircraft • Next on busy (e.g. media sharing with AOC) • Satellite service provisions are changing all the time • Major changes can and do affect performance • Systems components fail • Regional and ANSP monitoring and inter-regional exchange of monitoring results are essential

  12. PBCS – Performance Monitoring Example of ADS-C Report Delivery Time

  13. Inmarsat – What’s Coming

  14. Inmarsat – What’s Gone/Going

  15. PBCS – JCAB Evaluation of FOI • Some restrictions still apply • However, similar to FAA systems, JCAB systems have no operational means to determine the type of media the aircraft is using for FANS 1/A operations in the Fukuoka FIR • Reduced separations can be applied (or mis-applied) to FOI aircraft that indicate RNP4 in their flight plan • Use of flight plan (e.g. P2 indicator in Item 10) would resolve the issue

  16. AIRAC AIP SUP NR117/12 - 20 SEP 12 If FOI JCAB needs to extend to middle of 2014

  17. PBCS – FOI Current Status • FOI is a viable means to conduct CPDLC RCP 240 and ADS-C RSP 180 operations • Some implementations need improvement • Improvements to avionics continue • Understanding various systems interactions • CMU / MU managing sub-networks • Including Airline / Operator sub-network preferences • SDU / Iridium Ground System protocol interactions

  18. SATVOICE – Operational Evaluation • PARC CWG will base its SATVOICE work on ICAO Satellite Voice Guidance Material (SVGM) to facilitate global harmonization of U.S. initiatives • Flight plan information to identify SATVOICE equipment and capability • Item 10 – M1 (Inmarsat), M2 (MTSAT) or M3 (Iridium) • Item 18 – CODE/[aircraft address – hex representation] • PARC CWG • Established dedicated team to resolve issues with using Iridium Safety Voice service • Continues to working with FAA on policy updates

  19. SATVOICE – FAA MMEL Policy – HF • FAA Policy Letter PL-106 revision expected early 2014 Update from last meeting

  20. NextGen Domestic Data Link • Role of PARC CWG - items to consider • AC 120-70 update / Job Aid to include PBCS, FANS1/A, Link 2000+, Baseline 2 Data link, initial and on-going compliance • OpSpec/ MSpec / LOA template updates • Approaches for part 91 / GA / non-commercial operators • Training requirements • Airworthiness requirements • Input for B2 concept of operations • Collaborate with DCIT, SC214-WG78 and OPLINKP • Proposed project description in work

  21. FAA data link recording rules • Data link advances operational safety • Improves conformance monitoring for detecting large height deviations (LHDs) and gross navigational errors (GNEs) • Improves controller intervention capability thereby reducing the exposure of LHDs/GNEs • Retrofit installations of CPDLC recording capability • Excessive costs • Hinders the advancement of operational safety • Compromises NextGen implementation schedule • Preparing justification for recommendations to FAA

  22. Summary • PARC CWG recognizes U.S. initiatives must be globally harmonized for effective implementation  ICAO HQ and Regions • PARC CWG evaluates communication and surveillance technologies against global standards and specifications  GOLD / SVGM • PARC CWG is committed to performance-based concepts • PARC CWG/31 – 25-26 Feb 2014 in Miami, FL
