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

2. Define the Risks of T-PED’s to Aviation Safety
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. Defining The Risk of T-PED’s: Radio Sensitivity & Relative Signal Strengths
Distance to the moon
384,000 kilometers
Human Hair
40 µmeters
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

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 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

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

Recommended FAA regulation revisions to address allowable PEDs (Part 14 CFR and )
Conclusions on PED Spurious Emissions

12. When approved by RTCA, will be a separate “DO-YYY” document
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 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

13. Maintaining and Enhancing Aviation Safety: PED RF Emission Assessment
Foster Dialog with:

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
