Defining The Risk Of T-PED’sDefining The Risk Of T-PED’s

Unlike Avionics Systemsinstalled on airplanes,T-PED’s are consumerelectronics, purchased fromretail outlets and used by consumers without specific training.

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.

Distance to the moon

384,000 kilometers

Assessing The Risk Of T-PED’sAssessing The Risk Of T-PED’s

T-PED emissionsmay reach antennas used by sensitive airplane navigationand communications receivers. Unlike HIRF, the RF source is inside the airplane.

Assessing The Risk of T-PED’sAssessing The Risk of T-PED’s

Emissions fromT-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.

RTCA Special Committee 202RTCA 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

Safety:Safety:

Phase 2 Work CompletedPhase 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

03/16/2005

• 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

Concluding RemarksConcluding 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
