Learn about T-PED risks to aviation safety, RTCA SC-202 purpose, findings, and committee tasks. Explore RF emissions, airplane design, and ongoing efforts to enhance aviation safety.
E N D
Status of the work of RTCA SC-202 Co-Chairs:
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
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
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.
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.
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.
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 (PED’s). • 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-PED’s). • Phase 1 – current T-PED technologies • Phase 2 – upcoming, next-generation T-PED technologies plus guidance for airplane design and certification.

Accomplishments • 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.
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.
Maintaining and Enhancing Aviation Safety:RF Emission Limits Assessment • 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:Airplane Design and Certification • 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

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/
