03/16/2005 1 Status of the work of RTCA SC-202 Co-Chairs:
03/16/2005 2 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
03/16/2005 3 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
03/16/2005 4 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
03/16/2005 5 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.
03/16/2005 6 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.
03/16/2005 7 Maintaining and Enhancing Aviation Safety: RTCA Special Committee 202 The FAA requested that RTCA, Inc. form a special committee to present an up-to-date evaluation of the use of portable electronic devices (PEDs). Particular attention was to be paid towards intentional transmitters such as mobile phones, wireless RF network devices, and other wireless-enabled devices such as personal digital assistants (T-PEDs). Phase 1 – current T-PED technologies Phase 2 – upcoming, next-generation T-PED technologies plus guidance for airplane design and certification.
03/16/2005 8 RTCA SC-202 Schedule Special Committee SC-202 – Phase 1 Phase 2 2003 2005 January 2003 FAA Request May 2003 First Meeting October 2004 SC-202 Phase 1 Document Completed Previous PED Committees 1963 1996 April 1963 SC-88 Document Completed September 1988 SC-156 Document Completed August 1996 SC-177 Document Completed

03/16/2005 10 Developed and 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. Proposed FAR revisions to incorporate PED Usage Signage. Published recommendations on acceptable and enforceable use of T-PED geared towards: –Airlines, –Airplane Manufacturers, –Consumer Electronics Industry, –Regulatory Authorities, and –Consumers. Accomplishments
03/16/2005 11 Maintaining and Enhancing Aviation Safety: Continuing Efforts Refining recommendations for: –T-PED design –Aircraft design and certification –Operational risk mitigation. Assess and Characterize additional T-PED Technologies –Ultrawideband devices –Pico-Cell Technology –Wireless Medical Devices –Active RFID Tag Technology. Assess and recommend FAA regulation revisions to address allowable PEDs (Part 14 CFR 91.21 and 121.306). Increasing coordination with EUROCAE Working Group 58. Validation of the end-to-end process.
03/16/2005 12 Coordination with: –Regulatory Authorities –Consumer Electronics Industry –Avionics Manufacturers Develop recommendations for RF emission limit changes for consumer portable electronic devices –explore the possibilities for regulatory middle ground between Aviation Industry emissions requirements, and existing FCC limits for the Consumer Electronics Industry Maintaining and Enhancing Aviation Safety: RF Emission Limits Assessment
03/16/2005 13 Defining recommendations for Airplane Design and Certification: –address tolerance to intentional transmissions and spurious emissions –Identify PED environments to support: Aircraft certification System certification – STC –If required, identify changes to equipment RF susceptibility Will be a separate DO-yyy document –Completion after final update to DO-294 –Will build upon process and guidelines in DO-294 Work to define common document with EUROCAE Working Group 58 Expected completion July 2007 Maintaining and Enhancing Aviation Safety: Airplane Design and Certification
03/16/2005 14 RTCA SC-202 Schedule 2004 2007 October 2004 SC-202 Phase 1 Document Completed July 2006 Draft Document Completed December 2006 Document Publication Recommendation Phase 2 Tasks In Work 1 st Qtr 2007 SC-202 Phase 2 Document Released Review Comment March 2006 Phase 1 Document Update Released July 2007 Design & Certification Document Completed DO-YYY work
03/16/2005 15 Concluding Remarks Committee efforts provide level playing field for T-PEDs impact assessment. Making progress towards acceptable and enforceable policies and processes for the 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. Developing recommendations and process for operational allowance plans and for airplane design and certification Further information on RTCA and SC-202 available at http://www.rtca.org/ http://www.rtca.org/
