  1. Status of the work of RTCA SC-202 Co-Chairs:

  2. T-PED’s & Commercial Airplanes:Assessing the Risk & What To Do About It • Define T-PED’s • Transmitting - Portable Electronic Devices • Define the Risks of T-PED’s to Aviation Safety • Explain the purpose of RTCA SC-202 • Review the committee findings & recommendations • Address the committee’s remaining tasks

  3. Defining The Risk Of T-PED’s Unlike Avionics Systems installed on airplanes, T-PED’s are consumer electronics, purchased from retail outlets and used by consumers without specific training.

  4. Distance to the moon 384,000 kilometers Human Hair 40 µmeters Defining The Risk of T-PED’s: Radio Sensitivity & Relative Signal Strengths If the distance to the moon is compared to the transmitting power of a commercial airliner’s VHF radio , then the width of a human hair can break VHF squelch.

  5. Assessing The Risk Of T-PED’s T-PED emissions may reach antennas used by sensitive airplane navigation and communications receivers. Unlike HIRF, the RF source is inside the airplane.

  6. Assessing The Risk of T-PED’s Emissions from T-PED’s may be picked up by airplane wiring or nearby airplane systems devices themselves. Again, unlike HIRF, the RF source is inside the airplane.

  7. Maintaining and Enhancing Aviation Safety:RTCA Special Committee 202 • FAA requested that RTCA, Inc. form a special committee to evaluate use of current and next-generation portable electronic devices (PED’s) • Particular attention to be paid towards intentional transmitters (T-PED’s) such as mobile phones, wireless RF network devices, and other wireless-enabled devices such as personal digital assistants • Phase 1 – current T-PED technologies • Phase 2: – upcoming, next-generation T-PED technologies – guidance for airplane design and certification

  8. Committee Representation • Regulatory Agencies FAA (Flight Standards, Aircraft Certification, Spectrum Management), UK-CAA, Transport Canada, CAA-Brazil, DGAC-France, FCC • Airlines United, Delta Air Lines, US Airways, Continental, Northwest, American, Lufthansa, JAL, ANA, FedEx, UPS, Southwest, QANTAS, Air Wisconsin, ANA • Airplane Manufacturers Airbus, Cessna, Boeing, Bombardier, Embraer, Hawker Beechcraft • Avionics Manufacturers Rockwell-Collins, Honeywell, Connexion, Matsushita, General Dynamics, Teledyne, AirCell, Row 44 • Consumer Electronics Verizon, Intel, Sony-Erickson, Panasonic, QUALCOMM, XCube Communications, CEA, Sony, Motorola, Dell, CTIA, Freescale Semiconductor • Associations, Universities, Agencies NASA, UofOK, ARINC, SITA, ALPA, AFA, IATA, EUROCAE, Carnegie Mellon • Aviation IndustryConsultants CAVOK International, Alion, Eagle’s Wings, AJ Systems, Overlook Systems

  9. RTCA SC-202 Schedule August 1996 SC-177 Document Completed April 1963 SC-88 Document Completed September 1988 SC-156 Document Completed Previous PED Committees 1996 1963 January 2003 FAA Request October 2004 SC-202 Phase 1 Document Completed May 2003 First Meeting Phase 2 Special Committee SC-202 – Phase 1 2003 2005

  10. Accomplishments • Published guidance on a regulatory approval process for selective use of T-PED technologies • Provided examples of: • Characterization of current wireless technologies • Applicable aircraft avionics operating standards • Flight critical systems categorization • Mitigation of potential T-PED effects • Guidance for PED policies and procedures development • passenger and public education goals • Recommended revisions to FAA AC 91.21-1A(resulted in publication of AC 91.21-1B) • Proposed FAR revisions to incorporate PED Usage Signage • Published recommendations on acceptable and implementable use of T-PED focused on use by: • Airlines, • Airplane Manufacturers, • Consumer Electronics Industry, • Regulatory Authorities, and • Consumers

  11. Maintaining and Enhancing Aviation Safety:Phase 2 Work Completed • Refined recommendations for: • T-PED design • Aircraft design and certification • Operational risk mitigation • Characterized additional T-PED Technologies • Ultrawideband devices • Pico-Cell Technology • Wireless Medical Devices • Active RFID Tag Technology • Recommended FAA regulation revisions to address allowable PEDs (Part 14 CFR 91.21 and 121.306) • Conclusions on PED Spurious Emissions

  12. Maintaining and Enhancing Aviation Safety:Airplane Design and Certification • Documented recommendations for PED Tolerant Airplane Design and Certification: • Builds upon DO-294B process & guidelines • Addressed tolerance to both intentional transmissions and spurious emissions • Identifies standard requirements for equipment PED tolerancequalification and for target Interference Path Loss (IPL) • Provides process which may be used to demonstrate PED Tolerance as part of airplane certification • When approved by RTCA, will be a separate “DO-YYY” document • Approval expected in Mid-October 2007 • Actual “DO-number” assigned upon approval

  13. Maintaining and Enhancing Aviation Safety:PED RF Emission Assessment • Foster Dialog with: • Consumer Electronics Manufacturers • Avionics Manufacturers • Aviation Community • Document consensus recommendations on PED Spurious emissions • Facilitated by Consumer Electronics Association (CEA) • Joint CEA/SC-202 Working Group • Recommendations to be an addendum to DO-294B • Expected Completion 4Q2008 Work in Progress

  14. RTCA SC-202 Schedule Aug 2007 Design & Certification Document Completed 4th Qtr 2008 DO-294B Addendum Released 4th Qtr 2007 “DO-YYY” Document Release Expected December 2006 Final DO-294BDocument Released PED Emissions Recommendations Phase 2 Operational Guidance Design & Cert Document Dialog 2006 2007 2008

  15. Concluding Remarks • Committee efforts provide level playing field for T-PEDs impact assessment • Documented acceptable and feasible policies and processes for allowance of passenger and crew use of T-PEDs • Replacing anecdotal understanding of T-PED operation on aircraft with a common facts-based understanding of the T-PED impacts and situation • Documented recommendations and process for operational allowance plans and for airplane design and certification • Dialog with Consumer Electronics manufacturers to facilitate use of PEDs for our mutual customer base • Further information on RTCA and SC-202 available at http://www.rtca.org/
