1 03/16/ Status of the work of RTCA SC-202 Co-Chairs:

2 03/16/ T-PEDs & Commercial Airplanes: Assessing the Risk & What To Do About It Define T-PEDs –Transmitting - Portable Electronic Devices Define the Risks of T-PEDs to Aviation Safety Explain the purpose of RTCA SC-202 Review the committee findings & recommendations Address the committees remaining tasks

3 03/16/ Defining The Risk Of T-PEDs Unlike Avionics Systems installed on airplanes, T-PEDs are consumer electronics, purchased from retail outlets and used by consumers without specific training.

4 03/16/ Defining The Risk of T-PEDs: Radio Sensitivity & Relative Signal Strengths If the distance to the moon is compared to the transmitting power of a commercial airliners VHF radio, then the width of a human hair can break VHF squelch. Distance to the moon 384,000 kilometers Human Hair 40 µmeters

5 03/16/ Assessing The Risk Of T-PEDs T-PED emissions may reach antennas used by sensitive airplane navigation and communications receivers. Unlike HIRF, the RF source is inside the airplane.

6 03/16/ Assessing The Risk of T-PEDs Emissions from T-PEDs may be picked up by airplane wiring or nearby airplane systems devices themselves. Again, unlike HIRF, the RF source is inside the airplane.

7 03/16/ 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 (PEDs) Particular attention to be paid towards intentional transmitters (T-PEDs) 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 03/16/ 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 Industry Consultants CAVOK International, Alion, Eagles Wings, AJ Systems, Overlook Systems Committee Representation

9 03/16/ RTCA SC-202 Schedule Special Committee SC-202 – Phase 1 Phase January 2003 FAA Request May 2003 First Meeting October 2004 SC-202 Phase 1 Document Completed Previous PED Committees April 1963 SC-88 Document Completed September 1988 SC-156 Document Completed August 1996 SC-177 Document Completed

10 03/16/ 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 A (resulted in publication of AC B) 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 Accomplishments

11 03/16/ 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 and ) Conclusions on PED Spurious Emissions

12 03/16/ 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 tolerance qualification 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 Maintaining and Enhancing Aviation Safety: Airplane Design and Certification

13 03/16/ 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 Maintaining and Enhancing Aviation Safety: PED RF Emission Assessment Work in Progress

14 03/16/ RTCA SC-202 Schedule th Qtr 2008 DO-294B Addendum Released December 2006 Final DO-294B Document Released Phase 2 Operational Guidance 4th Qtr 2007 DO-YYY Document Release Expected Dialog Document Aug 2007 Design & Certification Document Completed Design & Cert 2008 PED Emissions Recommendations

15 03/16/ 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
