  1. Required Communication Performance (RCP) Moving toward a performance-based air transportation system Presented to: ICAO Worldwide Symposium on Performance of the Air Navigation System By: Tom Kraft, FAA, Aviation SafetyChief Scientific and Technical Advisor (CSTA) for Aeronautical CommunicationsEmail: tom.kraft@faa.govMobile: 202-369-2168 Date: 26-30 March 2007

  2. Overview • Current situation • A little about RCP • Activities underway • Outlook for implementation

  3. Introduction1995 air traffic data link services U.S. Goals: Reduce separations Reroutes User preferred trajectories Expose data link Applications: CPDLC, ADS–C Technology: FANS 1/A Airframe: Boeing 744 Equipment: Honeywell Collins Thales ATM Comm Services: ARINC SITA INMARSAT UAL ANZ QA Fiji French Polynesia Australia New Zealand

  4. Europe plans mandate for continental data link services • Partial CPDLC application • ATN services and aircraft equipage compulsory • Accommodation of FANS 1/A aircraft voluntary • FANS 1/A aircraft exempt from ATN aircraft equipage Introduction2007 air traffic data link services North Atlantic Region benefits from data link • In 2004, traffic levels exceeded pre–2001 levels • NAV CANADA has reduced communication costs to users by 50% • 55% of the fleet use either FMC WPR or FANS 1/A ADS–C for automatic position reporting PDC & D–ATIS via ACARS U.S. oceanicairspace boundary Pacific Sub–Region benefits from data link • Reduced separations to 50/50 NM and 30/30 NM (trials) • User preferred routes and reroute (trials) for all city pairs in South Pacific • Weather deviations • Automatic position reporting • 80% of the fleet in South Pacific use CPDLC and ADS–C, based on FANS 1/A, 60% in the Central Pacific, and 30% on average in the entire Pacific

  5. And then some • What will we do with • HF voice • INMARSAT Aero Classic Satellite Service • And what about • Voice communications, e.g., INMARSAT, Iridium • Data communications, e.g., HF Data Link, Iridium, Swift Broadband, Internet Protocol Suite (IPS)

  6. Harmonize data link services • Planning & Implementation Regional Groups • North Atlantic Systems Planning Group • European Air Navigation Planning Group Operational Requirements Data Link Steering Group (DLSG) andATN Accommodation Drafting Group (ADG) Standards for ADS-C RTCA/EUROCAE FANS 1/A - ATN Interoperability Standard Harmonize data link services RCP is a key element to the convergence process

  7. Continued operational safety Planning and Implementation Regional Groups (including subordinate groups) North Atlantic Asia-Pacific FANS Implementation Group (FIG) Informal South Pacific Air Traffic Services Coordinating Group (ISPACG) FANS Interoperability Team (FIT) Informal Pacific Air Traffic Control (ATC) Coordinating Group (IPACG) FANS Interoperability Team (FIT) FAA - Oceanic Separations Reduction Working Group (OSRWG) Scrutiny Group • Review operational data and advise based on results • Data link  VHF, Satellite, HF data link performance • Satellite voice  Security procedures

  8. Continued operational safety • Fluctuations in performance levels for commercial satellite services • Backups and redundancy • Dissimilar technologies, e.g., Iridium, HF data link, INMARSAT, data/voice • What are the performance criteria, what needs to be monitored, and what is the decision process • What about predicted performance?

  9. Standards & guidance material • ICAO completed standards and guidance material for RCP • Provisions for RCP in Annex 6 and Annex 11 • Manual on RCP  ICAO Doc 9869 • RTCA SC-189/EUROCAE WG-53 completed standards for data link services • Continental Safety and Performance Standard • Oceanic Safety and Performance Standard

  10. Performance-based operations • Balances capability & performance of • Communications, e.g., DCPC • Navigation, e.g., RNAV/RNP • Surveillance, e.g., ADS-C • Air Traffic Management • Builds on what we have to improve RCP RNP ATM C N S RTSP RSP What is RNP [x] airspace? What is applying separation using ADS-C?

  11. Performance-based communications • RCP type specifies communication transaction time, continuity, availability, integrity • Other operational factors may be relevant, for example • Messages or phraseology, transaction types, and intended use • Interactive capability of voice communication • Air–ground integration capability of data communication • Performance monitoring and alerting • Adapting the airspace to changes in performance level

  12. Objectives and benefits • Promotes a competitive market for aeronautical communication services enabling cost–effective alternatives that meet business needs in a more timely manner • Provides means to demonstrate communication performance using a variety of acceptable methods in lieu of time consuming data collection and empirical analyses • Defines “needed” operations based on communication performance levels that are not yet obtainable with current technology • Enables varying service levels in common airspace to a fleet of aircraft with varying communication capabilities and performances

  13. Applicability • When a change is implemented in air traffic management (ATM) and/or flight operations • And the change is predicated on communication performance • Safety management and monitoring

  14. What it does • Establishes operational criteria • Determines capability and performance criteria based on intended operations in oceanic, en route, terminal, and airport domains • Considers voice and data communications • Considers global seamless operations • Specifies RCP type and other relevant operational factors • Not based on any particular technology

  15. How it is used • Performance-based criteria is used to • Determine viability of a particular technology • Qualify, certify, and approve various parts of an implementation • Manage performance levels needed to provide a basic level of service and, for eligible operators, higher levels of service • Real time monitoring and alerting (air and ground) • Historical monitoring and evaluation • Adapting the airspace based on the results of monitoring

  16. Candidates for implementation • Reduced separation minima, new procedures, or increasing airspace capacity that requires a communication capability and performance • Operating in airspace with a basic level of service and, for eligible operators, with higher levels of service • Provision and use of air traffic service using non-traditional technology or mixed technologies • Communication capability installed on aircraft whose performance is suitable for use in some airspace, but not in others

  17. PARC (Who - What) • Performance-Based Operations Aviation Rulemaking Committee (PARC) • Operates under the FAA Administrator’s legal authority in accordance with 49 USC 106(p)(5) • Comprises members from the aviation community at large and FAA • Provides recommendations to FAA’s Senior Management for action & implementation • Effective in implementing RNAV/RNP

  18. Industry Coordination Draft Roadmap for Data Link present — 2025 Final Draft, 25-Jul-06 Federal Aviation Administration PARC Communications Working Group • Roadmaps, etc. • Build consensus among aviation stakeholders • Communicate fundamental capabilities • Assess benefit and investment • Set metrics to measure success of FAA implementation programs Roadmap for Performance-Based Communications

  19. Outlook • Complete industry-coordinated Roadmap for Performance-Based Communications by September 2007 • What are the applications for performance-based communications • What standards are needed and schedule • What is the strategy for aircraft type certification, operational approval, and implementation

  20. Outlook • Develop scenario outlines for implementation of RCP type, considering • Voice and Data communications to increase capacity • Oceanic and domestic (en route, terminal area, airport) • Operating in airspace with a basic level of service and, for eligible operators, with higher levels of service • Some existing communication capabilities and performance that are suitable only for basic level of service • Performance monitoring, alerting, based on RCP type, and adaptation
