Investigations into a system for the detection and location of potentially harmful radiation from portable electronics carried onboard aircraft

The problem of interference from portable electronic devices, PEDs, to avionics systems has been known for more than 30 years. This problem has been periodically studied but other than identifying the airlines as the responsible party for policing the situation, no hardware has ever been designed to combat the problem. The latest report on the subject from the RTCA, DO-233 suggested a hardware detection system as a possible safeguard against future problems. This paper describes the preliminary design of such a detection system.
