T-PEDs Commercial AirplanesAssessing 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
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
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.
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.
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.

Maintaining and Enhancing Aviation SafetyRTCA
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

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)

  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 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
